Performance-Based Planning and Decision Making - Understanding Mode Choices

This project will research the key drivers of multi-modal transportation choice, as they relate to individual households, annual household travel, household budgets and price sensitivity. The research will explore travel survey (household and transit) and consumer expenditure data. The general research findings will support planning questions on these topics, and will bolster Oregon Department of Transportation (ODOT), region, and local analysis capabilities specifically by implementing a module that can be plugged into existing tools, specifically the Regional Strategic Planning Model (RSPM). This project focuses on incorporating non-auto modes into a mode choice module for the RSPM tool utilizing existing data sources. To leverage this effort, ODOT research section and the project team at Portland State University applied for additional research funding at National Institute for Transportation and Communities (NITC) to expand the scope to emerging modes (especially bike sharing, car sharing and shared automated vehicles). In June, 2015, NITC awarded a grant of $120,000 for the proposal. Given the novel nature of the related NITC project, it will design and collect stated preference experiments data, analyze travelers’ perceptions and preferences for those emerging modes from this primary data source, and eventually incorporate these emerging modes into the RSPM mode shift module. The NITC project will convene a separate Technical Advisory Committee (TAC) with members from the academia and transportation professionals. Members of the TAC for this ODOT SPR project will have opportunities to be informed and/or involved in the NITC project, and vice versa.
