In a project funded by the National Cooperative Highway Research Program (NCHRP), Portland State University is partnering with the University of North Carolina at Chapel Hill and Safe Streets to develop guidance to help agencies identify the appropriate crosswalk spacing to ensure that people can cross arterials and other streets at safe crossing locations, and that a...

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors
Miguel Andres Figliozzi
Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood. When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable because at high speeds more vehicles can flow per unit of time and roadway section. However, high traffic/vehicles speeds are not desirable for pedestrians who have to cross urban arterials. In parti...
