Research Highlights

Understanding Types of Cyclists Nationally

Jennifer Dill
Nathan McNeil
Transportation professionals who are developing plans and projects that aim to change people’s travel behavior – such as getting more people to bicycle – need to understand the people they are targeting. To do so, planners and researchers have developed typologies of cyclists; however, many of these typologies are based upon surveys of current cyclists and, therefore, are of limited use in planning to attract new people to bicycling for transportation. One exception is the “Four Types of Cycl... Read More

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... Read More
