Naturally occurring and human-made emergencies occur every day on roadways.
Emergencies on roadways may be caused by multiple automobile accidents, fires,
earthquakes, landslides, radiation release, flooding, snow, ice, and chemical spills. The
impacts of these events may be limited to a road intersection or affect large sections of
a road network within the surrounding region. Emergency response systems provide
a mechanism for emergency services to receive notification of incidents, allocate and
prioritize resources, and respond to emergencies.
Emergency response systems were developed to facilitate notification and assist
emergency response personnel when responding to emergencies or crises. Some
of these systems are centrally monitored and provide a mechanism for emergency
managers and organizations to manage and allocate resources during emergency or
crisis responses. Automobiles or highways may be equipped with automated sensors
that notify emergency response systems when and where an incident has occurred.
Over the years, emergency response systems have transitioned from analog phone
communications to mobile and computer-based phones and sensors. As urban
populations continue to increase, road networks are becoming more and more
congested, leading to increased numbers of emergencies. Technologies and methods
for responding to emergencies have improved as a result. Several types of emergency
response systems exist on roads, including hazardous materials response systems and
automobile response systems for vehicle breakdowns and accidents. Notifications for
these systems may occur through the 911 Emergency Response System, intelligent
transportation systems, or automated notification systems. Emergency services,
such as police, fire, and ambulance, support the response systems, depending on
the type of event. During response to an incident site, agencies can use the Incident
Command System as a framework for managing and coordinating resources from
various agencies.

Resources
Many resources are used in support of emergency response systems. Real-time data,
such as aggregated cell phone location data and road conditions, provide up-to-date
information on where citizens are located and where authorities may need to respond.
Remotely sensed data, such as aerial and satellite imagery and closed circuit television
(CCTV), provide planners with visual information that can be integrated into emergency
response planning. For example, recent satellite imagery may provide information on
a new subdivision or retail establishment that was built in an incident area. CCTV is
often used to determine which citizens are responding to instructions from emergency
managers.
Often, geographic information systems (GIS) are used to assist with planning and
allocation of resources. Crisis resources are often geographically dispersed, including
police, fire, emergency medical services (EMS), hazardous materials (HAZMAT)
response, and airborne assets (helicopter, plane, and unmanned aerial systems). GIS
provides a toolset that can track assets and their locations and provide estimated arrival
times to an incident. GIS is frequently used to analyze data to support emergency
response. When an incident is identified, GIS provides tools to identify at-risk areas
that emergency response personnel need to prioritize for notification and allocation of
resources. GIS enables emergency response personnel to analyze citizens' locations,
identify the status of the road network, and determine the optimal evacuation route that
minimizes risk to citizens as they evacuate. With proper coordination from authorities,
GIS data and analysis can be shared among agencies on desktop computers, laptops,
tablets, and mobile phones.
It is imperative that planning for access to resources occurs prior to an incident.
Coordination between adjacent jurisdictions for data sharing is just as important as
mutual aid support. Agencies should ensure that in emergencies, data and analysis can
be shared with adjacent jurisdictions without contract violations (for example, sharing
remotely sensed imagery with other agencies to support their planning and response).
Joint exercises and training for support personnel that involves personnel from other
jurisdictions can assist with identifying problems that involve both jurisdictions, prior to

an incident occurring. Joint exercises and training also assist with building trust and
minimizing conflicts during an event.
Iowa Army Guardsmen assisted in rescuing the driver of this disabled car during a
severe snowstorm in Iowa City, Iowa, February 1, 2011. Emergency response systems
may eventually be able to make use of both vehicle-to-vehicle (V2V) and vehicle-toinfrastructure (V2I) communications. Data would be provided by each vehicle within the
network of wirelessly connected automobiles to the transportation network, allowing
other drivers to change routes and giving emergency responders advance details about
incidents.

Hazardous Materials Response Systems
Emergency response systems on roadways include systems for responding to
hazardous materials (HAZMAT) spills, accidents, and vehicle breakdowns. Planning
and response for each of these events may involve federal, state, and local agencies
and resources. Various chemicals, including toxic waste, radioactive materials,
gasoline, oils, and gases are transported on highways every day. Occasionally, a
transport vehicle is involved in an accident or has a leak or spill. Specially trained
personnel are needed during response to HAZMAT incidents to identify the material and
the impact to the surrounding area. HAZMAT-trained personnel work in coordination
with other agencies to secure the site and notify any personnel in the danger zone
where to evacuate. Emergency response systems enable planners to identify the
footprint of the danger zone, who is affected, and what additional resources are needed
to safely evacuate the area and clean up the spill.
Manual and Automated Notification
Systems
Traditional emergency notification involved an individual calling 911 and reaching a 911
operator. Universal emergency response systems, such as 911, were initially developed
with land-line communication and eventually adapted to support mobile phones. Current
911 calls can be geolocated to a mobile phone tower or an area within the mobile phone
tower footprint. To improve support to mobile phone customers during emergencies,
mobile phone companies and the Federal Communications Commission are working to
establish “text-to-911” and enhanced geolocation cabilities that provide the latitude and
longitude of mobile calls.
During the past two decades, automobiles have added sensor technologies that
automatically detect when a vehicle is involved in an accident (for example, when
the automobile's air bags are deployed or the vehicle is in a collision). Automated
[p. 484 ↓ ] emergency notification systems, such as OnStar (United States) or eCall
(European Union), relay messages to emergency services through automated and

SAGE knowledge
manual methods. For example, with OnStar, when a vehicle is involved in an accident,
an OnStar-trained adviser communicates with the driver and passengers. If assistance
is requested or there is no answer, the adviser sends a request to 911. The OnStar
system provides the adviser with the vehicle's global positioning system (GPS) location,
which is shared with emergency personnel. The vehicle also transmits direction and
number of impacts, rollover status, and maximum velocity at impact. OnStar advisers
share this information with first responders prior to their arrival, providing them with a
measure of the severity of the accident. These systems also offer methods to manually
request assistance or share information during a disaster or emergency.
The future of emergency response systems includes vehicle-to-vehicle (V2V) and
vehicle-to-infrastructure (V2I) communications. Automobiles, enabled with vehicle-tovehicle communications transfer and receive information from other vehicles, whereas
automobiles enabled with vehicle-to-infrastructure communications transfer and receive
information from roadside units, WiFi, mobile phone towers, or satellites.
Wireless access in vehicular environments (WAVE) includes V2I and V2V
communications. As WAVE is implemented, each vehicle within the network of
wirelessly connected automobiles provides data to the transportation network (vehicle
location, speed, etc.). This data enables other vehicles to change routes due to
congestion, vehicle accidents, and other hazards along a section of highway. WAVE
also provides additional information to emergency response personnel, such as the
severity of the incident, number of vehicles involved, and the appropriate resources to
use in the response (for example, fire, EMS, police, and HAZMAT).
The Incident Command System
The Incident Command System (ICS), which is a component of the U.S. National
Incident Management System (NIMS), is an emergency response system that
integrates equipment, personnel, facilities, communications, and procedures in a
common organizational structure. ICS is a standardized system that is used at the
site of an incident and supports all types of hazards. During a response, ICS provides
a hierarchical, top-down framework that enhances coordination between different
jurisdictions and agencies.

The incident commander is responsible for the incident and is supported by section
chiefs. The makeup of the sections is dictated by the type, duration, and scale of the
incident. Section chiefs include but are not limited to operations, logistics, plans, and
finance. The incident commander may also be supported by a public information officer
and a safety officer. ICS provides a standard process for planning and managing
resources. This ensures that when local agencies are overwhelmed or underresourced
for an incident, state and federal agencies can provide additional resources as needed
to support local authorities.
Regional Emergency Response Systems
Similar to some systems used in military operations, regional emergency response
systems such as Operational Situational Preparedness for Responding to Emergency
(OSPREY) and Regional Integrated Transportation Information System (RITIS) provide
a common operational picture (COP) of transportation networks in metropolitan areas.
These systems are tailored to support the needs of multiple agencies (for example,
HAZMAT teams, transportation departments, first responders, and others) within a
transportation region.
OSPREY is an Internet-based map developed for the Maryland Emergency
Management Agency. OSPREY provides situational awareness for numerous types
of events, including floods, power outages, open shelters, hurricane tracks, weather
watches and warnings to police and fire stations. Real-time data include weather
radar, CCTV, traffic conditions (speed, congestion, incidents, and active restrictions).
Information is shared through an open standard with the National Capital Region.
RITIS is similar to OSPREY; however, RITIS provides, fuses, and disseminates
information (traffic, events, parking, weather, signals, transit, and computer-aided
dispatch) from Delaware, Maryland, Pennsylvania, Virginia, Washington, D.C., and
West Virginia. Numerous federal users (U.S. Secret Service, U.S. Capitol and Park
Police, Federal Emergency Management Agency, U.S. Army and Air Force, Northern
Command, and the National Security Agency) use RITIS.

Emergency Response Systems
Coordination
The importance of emergency response systems is readily apparent during a largescale natural or technological disaster. However, a lack of coordination and planning
prior to an incident can result in communication challenges, lack of information sharing,
and failed response from multiple agencies. For example, are data formats compatible
and can data be readily shared with other agencies or jurisdictions? Do other agencies
have people who are properly trained to use the data, software, or resources needed
during an incident? Prior coordination, collaborative training, and exercises often identify
challenges emergency planners and decision makers may face during a real-world
event.
Social Media
Social media such as Twitter and Facebook have been increasingly used by emergency
operations centers to increase awareness in many regions, especially urban and
suburban communities. In conjunction with other notification networks, such as radio,
TV, and wireless emergency alerts (WEA), social media provide an alternative means of
informing the public and news media of events in a region.
Emergency response systems provide enhanced situational awareness to citizens
and emergency response personnel. Additional research on emergency response
systems, including the continued integration of geographic information systems and
multiple methods of communication (for example, social media, radio, TV, Internet, and
WEA), will enhance coordination and response to emergency incidents occurring along
transportation networks. Although OSPREY and RITIS provide enhanced awareness
of road networks, they lack situational awareness of rail corridors within the regions
of concern. Road networks are often severely impacted by emergencies along rail
networks, either directly or indirectly. The addition of rail transportation networks
to these systems would enhance situational awareness of cargo and passenger

transportation networks during an emergency.
