Research Highlights
Development of a Pedestrian Demand Estimation Tool
Kelly Clifton
There is growing support to improve the quality of the walking environment and make investments to promote pedestrian travel. Such efforts often require analytical non-motorized planning tools to estimate levels of pedestrian demand that are sensitive to environmental and demographic factors at an appropriate scale. Despite this interest and need, current forecasting tools, particularly regional travel demand models, often fall short. Until recently, spatially disaggregate travel behavior dat...
