PedPal is a prototype mobile (smartphone) app designed to assist pedestrians with disabilities when crossing the street at signalized intersections. PedPal interacts directly with the traffic signal system controlling the intersection to communicate both crossing intent (eliminating the need to seek out and push a pedestrian call button) and person

The GIS in Transportation team publishes quarterly newsletters to share information about significant geospatial transportation news, events, and applications. Each issue highlights a specific transportation agency's application of GIS or geospatial data and technology.
Modifying an existing intersection can improve both roadway performance and reduce emissions from vehicles moving through it. The Intersection Improvements Module of the Traffic Flow Improvements Tool estimates both performance metrics and emissions benefits for a single intersection for a project that: Installs a new traffic signal where a previou
