One distinct issue of urban freight systems-trip chaining behavior-is addressed in the modeling procedure. To shed light on the variables that play significant roles in affecting trip chaining behavior, two types or discrete choice models are estimated fly using a data set from the integrative freight market simulation. These models generate probabilities that help choose destination locations and make the decision about whether to return to the base or not for each tour until the known commodity O-D matrix is satisfied. The proposed modeling framework was applied to an 84-node test network. Results show that the estimated trip length distribution is consistent with the underlying data set. Meanwhile, several attributes are found to have significant effects on the trip chaining behavior. The choice of the next destination is negatively affected by the distance front the current location to the potential destination and positively affected by the amount of cargo available for pickup and delivery. For the tour termination decision, the perceived utility of returning decreases with the increase of the return distance and increases with the accumulation of cargoes delivered.

The paper analyzes the information gathered by a comprehensive outreach program which involved the use of focus groups, in-depth-interviews and Internet surveys. On the basis of the insights gained into the dynamic interactions among stakeholders, the authors discuss the corresponding policy implications and chief conclusions of the research conducted.

Relevant literature is discussed, and a mathematical formulation that can be integrated with a regional planning model is produced and applied to the selection of park-and-ride facilities in New York City. The evaluation procedure is divided into two main stages: candidate selection and candidate evaluation. The candidates are selected according to a set of criteria that includes demand considerations, transit connectivity and design, community integration, and economic viability. Economic assessment of the candidates considers the generalized cost of travel and entails the use of a binary logit model and the computation of four performance measures: expected demand, market share, weighted average savings, and present value of benefits.

The methodology proposed to estimate VOTT develops hierarchical Bayesian mixed logit models using travel surveys conducted as part of evaluation studies of PANYNJ and NJTPK facilities. The proposed approach is a novel method for examining commuters' behavior an the basis of flexible model specifications. Empirical results show that travel time, toll, income, and departure time are statistically significant parameters affecting VOTT of commuters on PANYNJ toll facilities. Mean VOTT estimates are found to be about $16.5/h for PANYNJ E-ZPass peak users and about $15.15/h for PANYNJ E-ZPass off-peak users, with standard deviation estimates close to $6.45/h during peak periods and $5.72/h during off-peak hours. Similarly, mean VOTT estimates are found to be around $16.3/h for NJTPK E-ZPass peak users and about $14.79/h for NJTPK E-ZPass off-peak users, with standard deviation estimates close to $5.481h during peak periods and $4.56/h during off-peak hours.

These policies include a tax deduction and shipping discounts for receivers, and customer requests combined with toll discounts, or financial rewards for carriers. Given the relatively small amount of research conducted in stated and revealed behavioral responses, the results for Manhattan and Brooklyn provide insights for the operations of receiver and carrier companies in areas of similar characteristics.

After presenting the key premises that should guide the development of FTG models, the paper assesses transferability in two different ways. The first one is through the analyses of how well representative FTG models are able to estimate the actual FTG at a number of (external) validation cases. The second one is through FTG econometric models that assess the statistical significance of binary variables that represent specific geographic locations. In addition, the paper introduces and assesses the accuracy of a synthetic correction procedure intended to improve the transferability and quality of the estimates provided by the FTG rates available in the literature. The results show that, the models developed as part of the project NCFRP 25 "Freight Trip Generation and Land Use" have better prediction capability than the ones included in other compilations; the synthetic correction procedures improves transferability; no locational effects are present in the test data.

Analysis of data collected by the authors, including behavioral and travel patterns before and after the time-of-day pricing initiative, revealed the following: (a) about 7.0% of individual drivers (6.6% of car trips) changed behavior as a consequence of the time-of-day pricing initiative, which translated into market elasticities for toll changes of -0.398 with the number of individuals used as the unit of demand and of -0.545 with the number of trips per month used; (b) users responded to thne-of-day pricing by implementing multidimensional strategies, including changes in facility usage, time of travel, productivity of car travel, and mode or occupancy; (c) users traveling relatively shorter distances exhibited more elastic behavior than those traveling long distances; and (d) only around 5% had more than one-half hour of flexibility and traveled during peak hours (they could be the target of the time-of-day pricing initiative because of the flexibility to shift to off-peak periods).

The sellers and transporters are modelled as non-cooperative Cournot-Nash agents. The sellers compete to capture receiver input factor demands, while the transporters compete to capture the transportation demand generated by the seller/receiver transactions. Each competing agent's extremal problem is formulated as an optimal control problem and the set of these coupled optimal control problems is transformed into a differential variational inequality representing the general Nash equilibrium problem. A nonlinear complementarity problem is also formulated and used to solve a numerical example.
