A framework for integrating pedestrians in travel demand models

This presentation will introduce a framework and proof of concept application from Portland, Oregon that facilitates the integration of walking activity into four-step travel demand models, allowing cities and regions to implement these advances with minimal changes to existing modelling systems. Specifically, the framework first changes the spatial unit from transportation analysis zones (TAZs) to pedestrian analysis zones (PAZs), a finer-grained geography better suited to modelling pedestrian trips. Then pedestrian trip origins and destinations are identified using trip generation and destination choice models. The opportunities and challenges for advancing and implementing this framework are discussed.  



Kelly J. Clifton is a Professor of Civil and Environmental Engineering at Portland State University. Dr. Clifton conducts research and teaches courses in various aspects of transportation planning and policy, including: travel behaviour, land use and transportation, physical activity and health, and travel survey methods. She is a affiliate of the National Institute for Transportation and communities and a fellow in the Institute for Sustainable Solutions, both housed at Portland State University. She was the inaugural chair of the World Society for Transport and Land Use Research. Her latest research develops methods to evaluate the transport impacts of new development, quantifying equity issues in transport, anticipating impacts and applications of “smart cities’ technologies, and modeling demand for non-motorized modes.
