Express buses operating on freeways and arterials are an important part
ofmany metropolitan area transit services. Aregional express bus system
plan for the San Francisco, California, Bay Area Is presented; network,
st...tion and stop, operations, and user Issues are addressed. Previous work
had focused on high-occupancy vehicles on freeways; the cnrrent work
expands the vision of the system to address the door-to-door trip and service on arterials. Gaps in the high·occupancy-vehicle network, priority
treatment strategies, access modes and connections, station and stop
design, park·and-ride lots, and public and private access services were
analyzed, and other user and operator concerns were addressed. The plan
was developed through a partnership that included the state transportation agency, the metropolitan planning organization, local transportation
sales tax and congestion management agencies, and transit operators,
with university researchers providing technical support and facilitation
of meetings. On·board surveys and consumer focus groups were conducted along with stakeholder interviews, field studIes, design evaluations, and simulation modeling. The plan not only produced valuable
information for future improvements but also helped develop a high level
of cooperation and consensus among the participating agencies. Both
methods used and lessons learned from the Bay Area experience should
be useful to other metropolitan areas and transit operators.
Express bus services are an important element in strategies for
improving urban mobility. Express buses offer customers a fast tide
by offeling limited-stop service to intermodal transfer points, work
centers, and other major destinations and by making use of priority
treatments to speed travel, including reserved lanes and ramps, signal
preemption, ramp meter bypass, and fast ticketing options.
In the San Francisco, California, Bay Area, numerous express
buses operate on the region's freeways and arterials, and the Californill Department ofTransportation (Caltrans), the Metropolitan TranspOl'tation Commission (MTC), transpOltation tax agencies, and the
region's transit operators work together to deliver these services.
Caltrans owns and operates high-occupancy-vehicle (HOV) lanes on
many of the region's freeways, as well as many of the park and ride
lots served by express buses. Caltrans also owns several of the major

arterials in the region. MTC, the region's transportation planning
agency, has planned and programmed additional HOV lanes and has
proposed a number of coordinated express bus services and stations
in key commute corridors. Several of the region's transportation sales
tax agencies have provided funding for express bus services and
facilities, including freeway and arterial priority treatments. With
voter passage of Regional Measure 2 in 2004, additional funds are
becoming available for new express bus services and for new HOV
lanes on the region's freeways and arterials.
Although the existing and planned express bus facilities and
services have clear individual benefits, this study was designed to
put together a system plan-a plan addressing all elements of the
system-for regional express service. Just as any system includes
network links and nodes, means of access, operating rules, and flows
on the network, the Bay Area express bus system plan addresses not
only network links (routes, HOV lanes, priority treatments) and
nodes (stations and stops, park and ride lots) but also the operating rules (schedule frequency and hours of operation, fares) and
flows (passenger demand, passenger preferences). The system plan
presents strategies for providing seamless, integrated service that
respond to traveler needs and improve travel options, while helping
to manage congestion, improve environmental perfonnance, and
support economic progress-regional objectives that are part of the
justification for investments in express bus services.
Issues identified as part of the planning process and addressed in
the plan include
• Bus users' concerns about the quality, reliability, and frequency
of express bus services;
• Gaps in the HOV lane network on freeways;
• Delays on arterials;
• Crowded park and ride lots; and
• Feeder service needs and costs.
This study was funded by Caltrans and was carried out in a partnership with MTC, county-level transportation tax agencies and congestion management agencies, and 12 of the region's transit operators.
Researchers at the University of California provided technical analysis, facilitated meetings, and prepared reports reflecting the consensus
of the partners.
In addition to producing a system plan that could guide future
detailed planning and design, programming, and investments, the
study aimed to identify ways to increase the effectiveness and use
of express bus facilities and services by developing an integrated
regional plan-a system plan-for improvements. The study built on
previous work sponsored by MTC that focused on freeway HOV lane
use, but it went beyond the MTC study to consider artelial services,
feeder services, park-and-ride, and other user and operator concerns.
The system plan develops both specific project recommendations and
recommendations for a process of ongoing cooperative planning and
implementation among service providers.
RESEARCH APPROACH
The study presented here was conducted in three phases. In the first
phase, the research team worked with the study partners to develop
agreement on a definitions and policy framework. In addition, the
research team
• Reviewed transit operators' current and proposed express bus
services, as well as a major proposal for HOV lane extensions and
new regional bus services developed by the MTC and Caltrans in an
earlier study (1). As part of this review, team members also interviewed operators to discuss their investment priorities and service
plans and met with congestion management agency and MTC staff
to discuss financing issues and opportunities.
• Reviewed 2020 forecasts for express bus ridership and analyzed
travel patterns and transit service quality elasticities to estimate
demand for an integrated, improved freeway and arterial express bus
network.
• Participated in public meetings designed to solicit broad
community input on express bus issues and needs.
• Explored alternative ways that a regional express bus plan might
be implemented.
The second phase of the study involved data collection and analysis to fill gaps in knowledge about user needs and concerns and operations altematives. The research tasks, each documented in a working
paper, included
• On-board surveys and ridership counts (1);
• Park-and-ride surveys and occupancy counts (2);
• Focus groups with express bus users and park-and-ride users
(who travel both by bus and by carpool) and with car drivers in transit
corridors (3);
• Study of access issues, including walk, bike, bus, and first and
last mile shuttles (4);
• Case study simulation of signal timing options, queue jumpers,
and so forth on arterials (5);
• Case study simulation of adding shoulder and median HOV
lanes (1-580 case study) (6); and
• Identification of needed capital and operational improvements
and first-cut cost estimates (7).
The study team worked closely with the study ad visory group in each
of these tasks, developing recommendations that had consensus
support.
In the third phase, the research team identified six additional
studies and demonstration projects that would proceed to implement
the regional express bus plan.
DEFINITIONS AND POLICY FRAMEWORK
In this study, regional express bus service is defined as any limitedstop bus service that moves people quickly between Bay Area cities
and communities. Study participants agreed that the regional express
bus system should include freeway flyers, bus rapid transit, and
cross-townand Transbay limited-stop services ("limiteds"), Hence
express buses may travel on freeways, on Jocal arterials and streets,
or on all three. Further, the partners agreed that the time required to
get to the express bus service and the comfort and convenience of
access, wait time, and transfers are all elements of the express bus
system and are critical factors affecting demand. Hence the express
bus system plan should address all aspects of door-to-door service,
not just express bus facilities and services themselves.
The research team and partners worked together to develop a policy framework reflecting this definition of the express bus system,
establishing standards and objectives for the key elements of the
regional express bus system as follows:
• Express bus routes should serve all major centers and intermodal transfer points, including rail transit and interregional rail
stops and stations and airports.
• Frequency and hours of operation should be matched to
demand. In major corridors, head ways of 15 min or less should be
the standard.
• Midday and evening express bus services should be provided
where work trip patterns or transit dependence data indicate a
need for such services.
• Subscription services should be provided for specialized needs
and should be considered for niche markets.
• The HOV lane network should be seamless; strategies to fill
gaps in the HOV network should be developed.
• Buses should be given priority treatment wherever congestion
would create delays, at freeway on-ramps and toll lanes, around
intermodaI stations, and at signalized intersections.
• Major stops (at transfer points or other major nodes) should
have full services, including comfortable waiting areas with shelter,
seating, lighting, real-time information, food and beverage services,
news outlets, telephones, and toilets. Other stops should have, at minimum, bus shelters with adequate seating and weather protection for
waiting passengers, covered passage ways for transfers, information
kiosks, and lighting.
• Route and schedule information should be posted at all stops
and be available over the Internet. Real-time information should be
available at major stops.
• Maps and graphics should be provided to orient bus riders to the
area around the station and the services available within walking distance, including local bus and shuttle connections, limed transfers to
express bus services, and nearby facilities such as cafes and public
restrooms.
• Point-to-point fare information should be provided, whether the
trip requires one vehicle and operator or multiple vehicles or operators.
• Fares should be affordable and should be equitable considering
costs of providing the service received.
• Security services should be provided for all stops and stations,
including park-and-ride lots.
• Passenger count data fmm express bus services should be supplemented periodically with rider surveys designed to document
origin-destination patterns, frequency of use, other travel choices
available, and customer needs and perspectives.
On the basis of this framework, the research team assessed the status of the current system and plans for improvement and identified
priority areas for the planning effort.
CURRENT AND PLANNED EXPRESS
BUS SYSTEM
Nearly 6.8 million people resided in the nine-county San Francisco
Bay Area in 2002, and nine outlying counties with considerable economic interaction with the Bay Area housed an additional 3 million
residents. Growth in the Bay Area bas been substantial, with six of the
nine counties experiencing double-digit percentage increases in population in the last decade. Outlying counties also bave experienced
substantial growth, with all but one of the nine adding population
faster than the state as a whole.
More than 3.5 million Bay Area residents were in the workforce
in 2000-52% of the population. In the nine outlying counties, there
were another 1.4 million workers. Although only about 70,000 of
these latter workers commute to Bay Area employment, their numbers are increasing, especially for work trips to job centers at the
fringe or the Bay Area. Some two-thirds of the workers begin their
journeys between 6:00 and 9:00 a,m. Another 15% to 20% will
leave for work between 9:00 a.m. and 4:00 p.rn.
The region's large population and workforce, much of it commuting during peak periods, constitute a major market for public transportation. The Bay Area is served by more than 20 bus systems, four
rail systems, two light rail systems, and four ferry services, as well
as numerous paratransit services. According to federal and regional
data sources, in 2000, nearly 1.2 million transit trips were made in
the region, accounting for 5.6% of all trips made there. Almost half
the transit trips were work trips, resulting in a 10.9% transit work trip
mode share.
The transit agencies currently operate 141 express bus routes,
including freeway flyers, rail feeder services operating express to
BART and Caltrain stations, and cross-town limited-stop routes.
Most express bus routes operate plimarily to serve commuters and
run only during the peak periods and in the peak direction. A small
number of express routes operate all day, often paralleling local bus
routes and providing a quicker option for long-distance travelers. In
2000, an estimated 138,000 trips were made each weekday on these
services-about 12% ofthe region's total transit trips that year.
MTC, in partnership with Caltrans and the region's transit operators, has proposed additional investments in regional express bus
services on nine freeway corridors that would operate in HOY lanes
or with HOY priority treatments. Interregional express buses, serving very-long-distance trips (30 mi or more one way) to Bay Area
job centers and intermodal transfer points (rail, air) from outlying
counties, also would use HOY lanes in some cOludors. Absent these
major investments, growth in express bus ridership is forecast to
increase by about 20,000 trips a day by 2020; with the investments
proposed, regionwide express bus ridership would increase by about
34,000 rides per average weekday, a 9% increase over the 2020 base
forecast.
However, of the 141 express routes currently operated, only 50
operate primarily on the freeway corridors that would be improved;
the rest run entirely on arterials and local streets. Onboard surveys
and ridership counts show that these latter services, which include
heavily patronized cross-town urbarl services, carry substantially
more riders than the freeway flyers, and they are likely to continue
to do so for the next 20 years. Indeed, because of the popularity and
effectiveness of these services, several transit operators are considering additional cross-town or cross-county limited-stop bus services and skip-stop rapid services. Upgrades of these services to Bus
Rapid Transit (BRT) standards are being implemented or are proposed for key corridors in San Francisco, Santa Clara County, San
Mateo County, and in the East Bay. In addition, combined circulator-express feeder services to rail stations and ferry terminals are
being expanded in some areas.
Express buses operating on arterials and local streets are important because despite the vast size and scale of the region, approximately half of Bay Area commuters are projected to travel fewer
than 10 mi to work in 2020, just as they do today. Three-quarters of
tile commute trips will be less than 20 mi, and 90% will be less than
30 mi, Whereas median trip distances will grow region wide in the
next 20 years, services that focus primarily on long trips will remain
aimed at a small part of the market. Trip distance analysis shows a
regional need for flexible express bus service that provides both
medium- and long-distance travel options.
Demand for express bus services depends, like demand for transit in general, on a variety of factors, including the availability of
competing modes and their performance, express bus availability
and service levels, price, and individual and household factors-the
fit between travel needs and the service offered. Considering both the
freeway and the arterial express bus services as targets for improvement, the research team estimated that the total regionwide ridership
increase could be nearly double the currently projected level, or
25% to 30% more than at present. For example, estimated elasticities of transit demand with respect to changes in access time, wait
time, and transfer time suggest that ridership gains of 20% to 25%
could be achieved. Additional increases could plausibly come from
improvements in passenger comfort and convenience, In addition,
new markets could be served with express buses.
Increases in ridership will be contingent on improved service levels on the arterials as well as the freeways. Cross-town limited-stop
services are impOltant alternatives not only for work trips but also
trips to school, shopping, and a variety of other activities. However,
buses cannot compete effectively with the auto ifthe buses are stuck
in the same traffic as cars and face additional delays moving in and
out of bus stops. Hence priority treatment is necessary for the buses
to be able to offer faster service. Just as HOY lanes, bypass signals
and lanes at ramps, and bus-only ramps are needed to make freeway flyer services operate competitively, wider stop spacing, signal preemption or signal priority treatment, bus-only lanes or queue
jumper lanes at intersections, and bus bulbs and other boarding
area design improvements are needed to speed bus operations on
alterials.
Access to the express services is also a major consideration. Buses
rarely can offer as direct a route as a personal vehicle, and access
time and wait can be a significant disincentive unless stops are comfortable, convenient, and safe. Cross-town limited routes, rapids,
and BRTs depend heavily on walk access to their services. Many
express bus services depend on a combination of park-and-ride lots
and feeder bus services for a substantial portion of their riders, with
walk and drop-off important access modes in some locations. If these
access modes are inconvenient, uncomfortable, or unsafe, they can
deter express bus ridership regardless of how excellent the service
offered by the express bus line may be.
Well-designed bus shelters and stations, equipped with real-time
information systems and other amenities, also can encourage ridership by making the wait and transfer more pleasant for users. Timed
transfers to and from other transit services (bus, rail, ferry) can
reduce delay and uncertainty and make the journey more pleasant.
All these improvements are needed if express buses are to operate as an effective system, providing high-quality door-to-door
services.
INFRASTRUCTURE AND
OPERATIONS IMPROVEMENTS
The Bay Area operates
• 300 lane miles of HOY lanes on mainline freeways,
• 50 lane miles of HOY lanes on expressways,
• l3lane miles of HOY or bus-only lanes on 16 arterials,
• Four bridge toll plazas with exclusive Janes for HaYs to pass
without paying tolls,
• Four HOY freeway-to-freeway connectors,
• Two HOV-only freeway entry ramps, and
• 66 HOV bypass lanes at metered freeway entry ramps.
Recognizing the successful performance of express buses and
their potential for helping to manage peak-period vehicle miles traveled, the Bay Area has planned new infrastructure to serve express
buses, including an expanded freeway HOV lane system and new
express bus terminals with parking and local bus connections. A
voter-approved ballot measure, Regional Measure 2, provides funds
for some of these new facilities as well as for additional express services in certain corridors. The improvements are being programmed
in two phases, as funds permit; the first phase adds 71 lane mi of new
freeway HOV lanes, a new freeway-to-freeway HOV connection,
two new and two expanded direct access ramps, three major freeway express bus stations, and 12 minor express bus stations. The
second phase will add an additional 87 lane mi of HOV lanes, live
freeway-to-freeway HOY connection, five direct-access ramps, and
six freeway express bus stations.
Considerable work remains to be done on some of these proposals, including locating the bus stations and, in many cases, obtaining land for them. Further, despite these planned investments, a
number of missing links will remain in the region's HOV lane network. On state highways, the gaps include 109 freeway lane miles
on 13 sections that are not yet congested, mostly at the fringe ofthe
region; 106 lane!TIi of congested freeway on 14 sections and 39 lane
mi of non-freeway routes where right-of-way limitations and potentially high construction costs have deterred HOY lane constlUction;
and 23 lane mi where a bottleneck upstream or downstream would
limit the effectiveness of an HOY lane. Some of these gaps are major
sources of delay.
Transit operators have identified a number of additional investments
that they believe would substantially improve operations. These
include improved signal timing along artetials, bus priority treatments
at major intersections, bus priority lanes and queue jumpers on
congested arterial segments, traveler information systems, bus shelters, park-and-ride lot improvements, and sidewalk and pedestJian
crossing improvements. These projects are for the most part low cost
compared to HOY lane or transit station construction and can be
highly cost-effective. For most of these improvements, it was found
that the annualized cost per rider per year was less than $2.
To explore ways to address the HOV gaps and to examine the
effectiveness of arterial improvements, tile research team conducted
two simulations: one of HOV lane additions on a freeway segment
and another of express bus improvements on arterials.
Simulating Alternative HOV Lane Designs
on Freeway Segment
For the many freeways in the Bay Area that lack right-of-way for
the addition of HOV lanes, alternative lane designs may offer a way
forward. Three possibilities are use of medians for the HOV lanes,
use of shoulders for HOV lanes, and use of a narrower lane design to
fit existing lanes plus an HOV lane into the existing right-of-way.
California has used medians for HOV lanes and transit ways on some
freeways; shoulder lanes and lanes that are narrower than standard
have been implemented successfully in several states, including
Washington, Minnesota, and Texas.
Determining the feasibility of alterative HOV lane designs would
require site-by-site analysis, which was beyond the scope ofthis plan.
To demonstrate a methodology for such analyses, the research team
used data from a section of the 1-580 freeway and used the Paramics
simulation model to test altemative design and operation strategies
(shoulder lane, median lane). The analysis showed the trade-offs
involved in median versus shoulder lane designs under different tJ'affic pattern scenarios and illustrated how simulations could be used
relatively inexpensively to explore alternative design strategies and
test alternative scenarios.
Two other strategies were identified for further study. One was to
consider whether ITS technologies could make narrow lane operation safer. Another proposal was to reconsider whether taking a lane
for HOV use might be acceptable in some locations, such as freeway
sections within San Francisco.
Express Buses on Arterials
Some express buses operate entirely on arterials and local streets, but
nearly all express buses operate on arterials some of the time, if oaly
to reach park-and-ride lots and terminals. Consider that most HOV
lanes offer time savings of 1 to 2 min per mile; this time savings could
be wiped out by 1 to 2 min unnecessary delay at intersections along
an arterial. Efficient signal timing and other spot improvements such
as queue jumpers at critical intersections are typicaUy low-cost strategies (e.g., signal timing usually costs no more than a few hundred
dollars per signal per year) and are sound ways to protect the benefits of HOV lanes (in the Bay Area, a $10 million per mile investment). For buses that operate entirely on arterials and local streets,
these intersection improvements can be critical to success.
The research team used several traffic operations models to evaluate alternatives for improving bus performance, by using data from a
major arterial, San Pablo Avenue, as the test case. The signal timing
software TRANSYT-7F was used to analyze the benefits of coordinated signal timing and bus-weighted signal timing (passive priority)
in comparison to individually timed signals with transit priority to
offset schedule delays, Longer pedestrian crossing times were also
tested. The Paramics microscopic traffic simulation modeling software was used to look at the effects of the altemative timing plans on
the parallel freeway as well as on the artelial itself and to test the
effects of bus queue jumpers created through minor widening and
restriping for narrower lanes at congested intersections.
In this case, the research showed that simply coordinating signal
timing produces significant benefits to transit and to general traffic
compared to individually timed signals (15% reduction in delays) and
that bus-weighted signal timing provides substantial gains to transit
vehicles (4% to 7% better performance than optimized timing alone)
and hence reduces person hours of delay with marginal detriment
to overall traffic flow. Queue jumpers were beneficial in some intersections and ineffective in others, depending on the number of turning movements being made in the intersection. Although the results
of such an exercise are case specific, the methodology demonstrated
could be used to test the effects of the full set of signal timing and
intersection improvements proposed by transit operators in the region.
INCREASING RIDERSHIP 1: EXPRESS BUS
USER SURVEYS
Most transit operators in the region have not conducted on-board
surveys for a number of years, so they had little information about
their passengers, their door-ta-door trips, or their preferences. To
better understand the demand for express buses, エィゥセ
study surveyed
passengers on 28 express bus routes operated by six transit agencies
in four corridors. Freeway flyers, express bus to rail, and limitedstop buses operating on arterials were included in the route sample.
Approximately 9,000 passengers were offered surveys, 5,477 surveys were accepted, and 3,354 surveys were returned, for a response
rate of just under 37%.
Results revealed significant differences between services and passengers in different corridors and by time of day. As might be
expected, peak-period express bus passengers made mostly work
trips, whereas midday users made trips for various purposes and had
lower employment rates and lower incomes. A less predictable finding was that the poorer passengers paid full cash fares more often
and made more transfers than their wealthier counterparts. Further,
allhough most of the bus routes serve park-and-ride lots, a surprising 50% of all riders walked from their homes to the bus in the
morning, with morning walk access rates as high as 68% for some
express bus lines. Most also walked from the express bus stop to
their final destinations.
Users' key concerns, as reported in the survey responses, were wait
times, waiting conditions, transfer times, schedule reliability, security,
and safety; from the respondents' perspective, in-vehicle times were
less in need of improvement. For many respondents, access needed
improvement; those who walked did not always have crosswalks or
sidewalks, and those who used feeder buses often complained that the
frequency and schedule of service was inadequate. Other major
concerns were the lack of security at park-and-ride lots, the lack of
shelters and lighting at many stops and lots, pOOl' inf0l111ation about
bus arrival times, missed transfers, and delays at major intersections
caused by traffic, poor signal timing, or no priority to buses. In contrast to operator assumptions that higher-amenity buses and faster
onboard speeds were top priorities, the survey respondents did not
rank these as major issues.
INCREASING RIDERSHIP 2:
PARK-AND-RIDE SURVEYS
Occupancy counts made it clear that many of the region's park-andride lots were full to overflowing, but almost no information was
available on who was using the lots or even whether those people
carpooled or took (ransit from the lots. The research team designed
and carried outthe region's first large-scale detailed study of parkand-ride facilities and users. Thirty-eight major park-and-ride lots
were surveyed with a fonn left on windshield with postage-paid
envelopes; three BART station (rail) parking Jots were also given a
modified survey designed to assess why drivers chose not to use
feeder buses to reach the station. A total of 1,289 surveys were
received from the freeway park-and-ride lots (return rate of 37%),
and 2,619 surveys were received from the BART lots (32% return.)
The surveys showed that almost all the parking users were commuters who used park-and-tide 4 or more days a week; at the freeway lots, half were transit users and the remainder organized and
casual carpoolers. Most park-and-ride users lived within 15 min of
the park-and-ride lot, drove there alone, and made very long trips to
work, many more than 30 mi one way.
At freeway park-and-rides, almost allllsers park in the same lot
each week, and if spaces are not available, they park in nearby
neighborhoods or drive. Freeway park-and-ride users' number-one
concern was for more parking spaces, since most found it frustrating to not find a space at their preferred lot. Respondents from the
freeway lots also had concerns about the lack of lot security and
lighting, poor cleanliness (litter. broken glass, pigeon droppings),
and the absence of user amenities, such as shelters, toilets, newspaper
boxes, and beverage outlets (vendors or machines). Many commented negatively about the lack of illfom1ation on bus schedules
and routes and the absence of ,my way to find out what was going on
if a bus were late.
In contrast, BART riders, who do have security, lighting, maintenance, and user amenities available at the station or directly adjacent
to it, had far fewer complaints; their main wish was for more parking. BART riders tend to use a different BART lot if their primary
lot is full.
INCREASING RIDERSHIP 3: FINDINGS FROM
FOCUS GROUPS
To further explore the viewpoints of express bus users and to find
out mOl'eabout those who choose to drive or carpool instead of take
the bus, 13 focus groups were held with Bay Area commuters. The
discussions were used to follow up on concerns raised in meetings
with transit operators and at public outreach meetings, to supplement transit and park-and-ride user surveys, and to deepen the
understanding of the commuter attitudes toward existing transportation options and possible improvements. Separate focus groups
were held with transit users (seven groups), carpoolers (two groups),
and drive-alone commuters (four groups) in different parts of the
Bay Area. The 140 participants were recruited by using flyers handed
out on board and at park-and-ride lots and were recruited from a
FastTrak (toll tag) database (tag holders who hac! agreed to be invited
to participate in meetings about transportation issues).
Focus group participants said that the most onerous aspects of
regional express bus service were waits and transfers. Waits could
be made more appealing by providing shelters, lighting, and other
amenities; schedule adherence would help make waits more tolerable and make transfers work better. However, many of the participants believed that offering direct (one-bus) service to job centers
in San Francisco, Oakland, Berkeley, and the South Bay would be
even more appealing. Many participants were doubtful that timed
transfers could be improved significantly; they pointed out that most
transfers are already timed but are missed wheuever a bus is delayed
because of an accident on the freeway or delays on signalized arterials, for example. Real-time information systems appeared useful
to the participants, but many cautioned that this would not overcome
infrequent service or missed transfers.
Although focus group participants were unenthusiastic about
transfers to and from other transit vehicles, a number of participants
spoke favorably about mixed services that collect passengers at several neighborhood stops, then ttavel express to job centers. Others
spoke favorably about employer and community shuttles that served
the same function from key terminals.
Focus group members also wanted to see key parking lots
expanded and revealed a willingness to pay $1 to $3 a day for a parking space in exchange for increased amenities, such as security and
shelter. Few, however, were willing to move to one of the underutilized park-and-ride lots, pointing out that most of these lots are
too fm' away from their commute routes or are on the wrong side of
the freeway (inbound direction in the morniog with immediate off
or 00 access is prefelTed). In addition, very few believed that a parking sU'ucture would be more desirable necessarily than surface parking, and some were uncomfortable with parking garages. Most would
not be interested in a parking structure if they had to pay the full cost
of parking (probably $5 to $8 II day, or more).
Drive-alone commuters included those who were indifferent to
San Francisco's high parking costs, those who needed their cars during the day for business trips, and those who would rather park in
San Francisco residential neighborhoods and move their cars every
few hours to avoid a ticket than to take the bus services available to
them-usually those bus services that require multiple u·ansfers.
Many of the drivers in all three categories reported that their transit
options took several times longer than driving. The discussions also
explored the appeal of casual carpooling, a significant competitor to
transit and driving in many parts of the Bay Area. Most casual carpoolers have tried transit and found it wanting, especially when multiple transfers are needed to reach their destinations; many also enjoy
the spontaneity and independence of the anonymous carpools that
form at many park-and-ride lots. However, a large share of both driving and carpooling commuters would be willing to try express bus
(or rail) service should it provide a comfortable, one-seat ride to
employment centers for a reasonable price.
GETTING TO THE EXPRESS:
BUS AND SHUTTLE ACCESS
The focus group participants drew the research team's attention to the
importance of feeder services at both ends of the express bus trip.
However, outside central business disu'icts and a few high-density
neighborhoods, transit operators typically provide only limited feeder
bus service. The research team investigated shuttle programs that have
been established to address this gap.
Bay Area employers and local govemments have created more than
150 shutLle programs to provide or enhance feeder services in "first
and last mile" markets. Three models for shuttle organization have
been identified: the single-employer shuttle, the multiemployershopper-hotel shuttle or circulator, and the community shuttle. The
first two types of shuttle largely started as traffic management requirements (developer exactions) but have come to be seen as employee
benefits or business support strategies. The community program
often has grown out of a multiemployer service, as the local government partnered to serve its own employees or to handle other
community needs, such as senior transport or after-school transpOit.
Shuttle services use a variety of vehicles matched to market, from
used buses to vans. Costs generally run $50 to $60 an hour-about
the same as the least expensive conventional bus provider in the
region and less than half the higher-cost providers' rates. Drivers
often are unionized, but work rules are flexible and services are
agile, responding to market shifts quickly. Relations with conventional transit often are positive, with the shuttles seen as providing
valuable feeder services and supplementary services.
Major achievements include serving a collective total of 8 million
riders a year and the attraction of substantial business support and fundiog. Ongoing challenges include coordination with transit agencies
and other transportation providers, finding a stable source ofcosts and
funding, especially if shuttle services are to expand, and finding strategies tl1at work for the underserved first mile. Despite tllese challenges,
the shuttles deserve ongoing attention as an important supplement and
possible alternative to park-and-ride and feeder buses.
RECOMMENDATIONS
The planning effort has led to a series of recommendations:
• A broad definition of express bus services should be adopted,
including cross-town limited and BRT services operating on arterials and local streets as well as freeway express buses; these latter
services carry a large share of current and future passengers.
• Planning attention and funding must be given to door-to-door
service, including access modes (walk, park-and-ride, feeder bus,
shuttle) at both ends ofthe trip, travel conditions around stations and
along arterials, and transfers.
• Gaps on the HOV network that will be hard to fill though conventional widening that adds a lane might be addressed through
restriping for narrower lanes or through use of shoulder lanes and
median lanes. Simulation software should be applied to test the performance of alternative designs and explore the effects of different traffic patterns. Gaps where there is no congestion should be
studied for ways to implement HOY lanes (e.g., right-of-way preservation or advance acquisition) eventually, since most such gaps are
in fast-growing areas.
• Express bus performance on al1erials is critically important,
and significant improvements can be made at relatively low cost by
coordinating traffic signals, implementing bus-weighted (passive
priority) signal timing, and adding queue jumper lanes for buses.
Strategies for improving pedesuian crossing times also can be
implemented, improving access. Traffic signal timing and simulation software should be used to test alternative operations strategies
and identify the most cost-effective ones. Funds should be made
available for tlIese improvements.
• Limited or inadequate access (poor walking and biking conditions; inadequate and poorly maintained park-and-ride lots; infrequent feeder services; lack of shelter, lighting, and amenities at stops)
m-e a major deterrent to express bus use and should be high priorities
for expenditure. Many express bus users walk to their bus stops, and
improvements in pedestrian facilities and waiting areas should be
considered to be at least as important as park-and-ride facilities.
• Better information at stations, stops, and park-and-ride lots is
desirable but will not compensate for poor access. Rather, information systems are an amenity that will be useful primarily for new or
occasional users (not a big percentage of express bus users) and for
unusual events (the occasional accident or breakdown that delays a
bus, for example).
• Most express bus services focus on peak-period commuters,
but at least in some corridors there is a demonstrated market for
school trips.
• Park-and-ride lots should be expanded by redesigning layouts
as a first, low-cost strategy. Maintenance and amenities should be
added, and user fees should be evaluated as a way to pay for at least
part of the improvements.
• Planning and implementation efforts should be mindful that most
travelers prefer direct services and are skeptical about timed transfers.
Where the market would support direct service, such service should
be tested.
• Shuttles should be considered as an environmentally friendly
alternative to park-and-ride lots and may cost less per ride. Shuttles also might be considered as a substitute for marginal feeder
bus services. A program to more formally engage employers, local
businesses, and cities in funding shuttles could be pursued.
Many of the recommendations for action could be funded with
regional and state planning funds; state highway operations funds;
federal and state highway and transit funds programmed by MTC
or Caltrans (depending on the facility and project type); federal,
state, and regional transit funds; county transportation sales tax
dollars; public-private partnership funding; or user fees. The key
funding need is to include all elements of a high-quality systemnetworks, nodes, means of access, operations, user needs-into
the funding package.
NEXT STEPS
The research team recommended six projects that would help Caltrans
and its parlners further refine and carry out portions of the regional
express bus system plan.
Proposed Project 1. Arterial Operations and
Context-Sensitive Design Improvements
Along Express Bus Corridors
Transit operators ill many patts of the region have identified delays
at signals as one of the major frustrations in operating express buses.
Even buses that operate primarily on freeways experience delays at
signals as they go to and from terminals and park-and-ride lots.
Many of the signal problems could be reduced or eliminated by better signal timing, by adding a left-tum phase, or by providing a queue
jumper to allow buses to bypass congestion.
Along a transit corridor, putting together a package of signal
upgrades, signal timing improvements, and minor capital improvement projects could greatly improve the on-time pelformance of
transit services. User-friendly improvements to sidewalks, bus shelters and benches, landscaping, and pedestrian lighting may attract
additional riders to express bus services. Context-sensitive design
strategies could lead to new and more creative ways of managing
vehicle and pedestrian traffic. Finally, even more riders likely would
be attracted if traffic operations and streetscape improvements were
combined with efforts to renovate and revitalize the land uses and
activities along the corridor, as part of a community plan.
In this project, Caltrans would request proposals for demonstration
projects and would work with successful applicants to develop a
design plan for the demonstration corridor that would fulfill the overall objectives of the program: improved transit speed and reliability,
improved pedestrian and transit user facilities, improved traffic operations, and street designs that respond to community concerns and
support revitalization. Once a plan was developed and approved by
all parties, the partnership members would apply for grants to develop
and implement the corridor plan. Caltrans would also support the
monitoting of both the planning process and a postimplementation
corridor performance evaluation I to 3 years after implementation.
Proposed Project 2. Use of Innovative
Lane Designs for HOV Operations
Plans are under way to add HOV lanes to close some of the gaps
in the Bay Area's HOV lane network, but many other gaps are
likely to persist, usually because right-of-way is not available or
is prohibitively costly.
Several states, including, Texas, Washington, and Minnesota,
have successfully added freeway lanes under such circumstances by
using a narrower lane than standard to fit an additional lane into
available right-of-way (Texas) or by allowing HOV lane operations
on shoulders or medians. These strategies require careful engineering
analysis and operations testing and should be considered case by case.
The work in the second phase of the study demonstrated some of the
pros and cons of alternative lane designs in a simulation study, but it
was not possible to simulate all possible candidate sites for added
lanes, nor was the research team able to investigate the engineering
feasibility of the alternatives.
Such detailed investigations could be canied out on other candidate locations and, if these investigations show that the lane additions
would be feasible and acceptable, demonstration projects could test
their utility, safety, comfort, and convenience. (Design exceptions
might be needed to proceed.) Funding for the demonstration nlight
come from Caltrans, MTC, or a county tax authority.
Proposed Project 3. Alternative Layouts and
Parking Space Standards for Park-and-Ride Lots
Surveys of park-and-ride lots in the Bay Area found that many lots
are at or close to official capacity, and many others are likely to
reach capacity in the next 10 to 20 years. Many of the most popular
park-and-ride lots are holding more cars than there are marked
spaces, because dtivers park along driveways and in other unmarked
areas of the lots. Marking these spaces when they are safe would
gi ve both drivers and the lot operators a better sense of where it is
acceptable to park and where it is not.
In many park-and-ride lots, the size of each space far exceeds the
space requirements of most parked vehicles. The Cal trans space and
aisle dimensions are larger than those recommended by many parking experts, including the Urban Land Institute, and are significantly
larger than the space sizes required by a number of local agencies,
such as Alameda County. Although large spaces are a convenience
when land is not scarce and parking is not running short, the current
situation would suggest that parking dimensions be revised downward. A smaller overall parking stall and aisle standard or a separation of large vehicles into a separate area are two possibilities. The
adoption of this strategy would be inexpensive and in some lots
could substantially increase parking capacity, allowing more people
to use the express bus or a carpool from the lots. In addition, at some
lots, bus access and egress are difficult; redesign of the lots could
improve this, reducing bus run time and costs.
Starting with lots that are at or very near capacity, in this pl'Oject
planners and engineers reviewed layouts and developed alternative
designs either by using a more modest stall and aisle dimension overall or by creating a separate area for large vehicles (SUVs, trucks,
etc.). They then identified or developed alternative design standards,
by working with a Caltrans-transit operator-other stakeholder working group. New parking layouts would then be developed by using
the design standards tailored and applied as appropriate to the specific circumstances of each of the lots needing redesign. For example, the designs should facilitate bus access and egress, including
relocation of driveways and aisles as needed. A demonstration project then would be carried out to test the effects of the alternative parking standards and layouts (e.g., test if any accidents are attributable to
smaller spaces or if motolists voice complaints or praise the results).
An evaluation would be carried out on 6-month and I-year data, and
decisions on whether to expand the use of alternative design standards
would be made on the basis of the findings.
Proposed Project 4. Land and Right-ot-Way
Strategies for Park-and-Ride Lot and
HOV Lane Expansion
A number of park-and-lide lots might be expanded and HOV gaps
filled if land for their construction were uvaiJabIe. In some cases, a
reconfiguration of the lot or lane on state-owned land may be feasible.
In other cases, other publicly owned land (e.g., held by a city or
county) might be obtained, or privately held land might be purchased.
Other possibilities include land swaps, long-term leases, shared parking, and joint development. An additional option suggested by a transit operator would be to use offfreeway rightofway or surface street
lanes paralleling freeway sections as bus priority lanes in sections
where a freeway HOV lane cannot be accommodated.
A project to investigate these strategies and to recommend strategies for obtaining land for parkandride facilities (expansions or new
lots) and for HOV lanes and ramps could examine the alternatives,
investigate the legal issues and institutional arrangements needed,
and recommend steps to obtain the needed land or land rights.
Proposed Project 5. Charges for Park-and-Ride
Maintenance and Amenities
Parkandride survey respondents frequently complained about the
poor upkeep and lack of amenities at most parkandride lots. These
facilities have been provided free of charge, and state and local
funds for maintenance have been difficult to secure. Some transit
operators in the region are beginning to charge for parkandride,
and in surveys and focus groups most parkandride users said they
would be willing to pay a modest daily fee for maintenance and
improvements (shelters, lighting, seating, toilets) at the lots. Tllis
project would carry out further studies of willingness to pay, identify candidate lots for pricing and improvements, and design, implement, monitor, and evaluate one or more demonstration projects
testing the effects of pricing on consumer satisfaction with and use
of the lots.
facilities. Other operators could be transit agencies, ridesharing
agencies, congestion management agencies, local city or county
public works departments, redevelopment authorities, private entities, or combinations of the above through publicprivate partnerships. Moving to alternative arrangements could be costeffective
for all concerned and could open new possibilities for improving the
efficiency and effectiveness of the lots, such as stacked parking,
shared parking, structured parking coordinated with adjacent land
development, and flexible pricing (e.g., with or without a transit ticket,
reserved space). This study would evaluate the legal, institutional, and
operational issues involved in alternative institutional arrangements
for parkandride facilities (which may vary by location or lot, as
opportunities differ).
