Project Details

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.

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.

Deliverables

Deliverable Name: 
Task 2 Synthesis of Current Traveler Choice Research
Deliverable Type: 
Research report or guidelines
Deliverable 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.
Deliverable Name: 
Task 3 Gap Analysis: Workshop and Survey Results
Deliverable Type: 
Research report or guidelines
Deliverable 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.
Deliverable Name: 
Task 6.1 Final Report
Deliverable Type: 
Research report or guidelines
Deliverable 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.
Deliverable Name: 
Task 6.3 Inventory of Datasets
Deliverable Type: 
Data
Deliverable 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.
