Office of Operations Research and Development |
|Team:||Trans Ops Concepts and Analysis Team|
|Project Description:||Although advancement in technology has made it easier to collect traveler choice data, it is still difficult to capture attitudes, motivations, influences, and the context within which choices are made. The primary objective of this project is to advance our understanding of choices made by travelers under various factors in network and nonnetwork conditions and the impact of traveler choices on the operations (e.g., recurrent and nonrecurrent congestion) and safety (e.g., mode switch on inclement weather) of the transportation system and design effective interventions (e.g., Active Transportation and Demand Management strategies) to improve system performance. At the conclusion of this work, a suite of traveler choice data and adjustment factors will be available to incorporate and enhance the existing transportation analysis tools. This project will also serve as a lead and encourage States and local agencies and the rest of the transportation community to develop and use national and regional traveler choice data and adjustment factors to improve their transportation models and forecasts. Four key deliverables will be generated from this study: (1) A synthesis of current research and practices to be published as an independent report.(2) A final report that will capture the effort of all activities and future research direction.(3) An inventory of traveler choice datasets collected.(4) Proven procedures to incorporate traveler choice adjustment factors in a selected numbers of transportation analysis tools.|
|Start Date:||June 1, 2011|
|End Date:||September 30, 2013|
|Goals:||The primary objective of this research study is to advance our understanding of choices made by travelers under various factors in network and nonnetwork conditions and the impact of traveler choices on the operations and safety of the transportation system.|
|Test Methodology:||The test approach is to: (1) Review the current state-of-the-art traveler choice research. (2) Analyze the gap between “where are we now” versus “where we want to be” on this topic. (3) Select scenario specific examples for indepth traveler choice analysis and collect data. (4) Develop methods and demonstrate procedures to incorporate traveler choice adjustment factors in several transportation analysis tools.|
|Expected Benefits:||Accurate traveler choice data that realistically emulates people’s decisions regarding route selection, mode choice, and time of departure will improve forecasts for various transportation applications. At the conclusion of this study, it is expected that a suite of traveler choice data and adjustment factors will be available to incorporate and enhance the existing transportation analysis tools.|
|Deliverables:||1. Name: Task 2 Synthesis of Current Traveler Choice Research|
Product Type(s): Research report
Description: Task 2 deliverable on the Synthesis of Current Traveler Choice Research. This deliverable will be submitted for publication as an independent report. The objective is to have this available for the 2013 Transportation Research Board conference to spread the word on current practice and gaps of traveler choice research.
2. Name: Task 3 Gap Analysis: Workshop and Survey Results
Product Type(s): Research report
Description: The purpose of Task 3: Gap Analysis of Existing Resources and Knowledge versus Desired Results, is to analyze and characterize the gap between where we are now versus where we want (and need) to be on the topic of travel behavior.
3. Name: Task 6.1 Final Report
Product Type(s): Research report, Support, Draft standard, specifications, or guidelines
Description: The deliverable is a detailed report documenting all research efforts, findings, and recommendations. The final report will summarize the results from Tasks 2 and 3 (referring interested readers to the Task 2 and Task 3 reports for more information) and provides detailed descriptions of the results of Tasks 4 and 5.
4. Name: Task 6.3 Inventory of Datasets
Product Type(s): Support, Data
Description: To the extent applicable, we will produce inventories of datasets, one for each scenario. Each inventory of datasets used in scenario model and simulation runs.
