A framework for integrating pedestrians
This presentation will introduce a framework and proof of concept application from Portland, OR 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 modeling 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 modeling 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.
