Impact on Practice
Integrated Advanced Travel Demand Model with Mode Choice Capacity and Finely-Grained, Time-Sensitive Networks
(C10 A &B)
The integrated models dynamically evaluate the interplay of traveler behavior and transportation network conditions, including mode options. The transferability of model parameters was investigated.
|With more realistic estimates of travel demand—and how it changes when mode choices are available— agencies can make more informed decisions about adding highway and transit capacity, improving traffic operations, introducing priced roads, and improving traveler information.
The software is available via an open source license; manuals and documentation are included. Pilot tests to validate the results and refine the usability of these tools are ongoing. Implementation is expected to begin in 2014. Model sets are available for Jacksonville, FL, Sacramento, CA, and Burlington, VT.
Staff Responsibility: Stephen J. Andrle
Recent advances in both model demand and supply components create an opportunity to develop more robust travel models for use in transportation decision-making.
The goal of Project C10 was to improve modeling and network processes and procedures in order to address policy and investment questions that cannot be well addressed now, and to facilitate further development, deployment, and application of these procedures. The primary objective of this project was to make operational in two public agencies adynamic integrated model–an integrated, advanced travel-demand model with a fine-grained, time-dependent network (integrated activities and networks). The secondary objectives of this project were to: (1) Produce a portable and transferrable, product, process, and sample data set that can be adapted for use elsewhere or used for research; (2) Incorporate SHRP 2 Capacity products from projects C04 (pricing) and C05 (operations) into the model capabilities; (3) Incorporate travel time reliability into the modeling capabilities; (4) Demonstrate the application of outputs of the integrated model to estimate greenhouse gas emissions using EPA’s MOVES Model; and (5) Demonstrate the dynamic integrated model set in a real-world environment on selected policies listed in this RFP.
Project C10B was intended to serve communities with more mode choices than those in project C10A, to take into account mode choice response to highway conditions. Project C10B developed a methodology to reflect changes in the nature of demand, mode choice (including “new modes” such as work or shopping at home and nonmotorized travel), destination choice, timing, and route of travel as a response to transit service, highway network congestion, roadway management strategies, road pricing, parking policies, and other public policies aimed at reducing congestion.
While the primary project objective called for the development of a dynamic integrated model with advanced policy analysis capabilities, it was also important that it be feasible for advanced practitioners to implement the model system in other regions without excessive costs or undue complexity. This resulted in a model system that is scalable and relatively easy to implement and maintain, while not requiring a lengthy, expensive implementation and maintenance effort.
Status: The project is complete.
