Development of a Pedestrian Demand Estimation Tool
Kelly Clifton
There is growing support for improvements to the quality of the walking environment, including more investments to promote pedestrian travel. Planners, engineers and others seek improved tools to estimate the level of pedestrian demand that are sensitive to environmental and demographic factors at the appropriate scale to aid policy-relevant issues like air quality, public health, and the smart allocation of infrastructure and other resources. To this end, a previous OTREC-funded project "Imp...

Bicycling is enjoying a surge in popularity across the USA but bicycle safety continues to remain a challenge. Cyclists (and pedestrians) are the most vulnerable road users since cyclist-vehicle collisions often result in severe injuries and have high fatality rates with respect to other types of collisions. In particular, intersections are one of the most critical areas in a road network given the high number of conflicts and accidents occurring at these locations.
Although there has bee...
