DESCRIPTION: The objective of this project is to enhance both safety and accessibility for non-motorized road users (henceforth referred to as active users) at signalized intersections in urban areas. This project will build on the team’s work for an existing project with WSDOT and make use of sensing technology developed in the PI’s lab, notably the Mobile Unit for Sensing Traffic (MUST sensor). The core of this project involves two main components: (1) development of a framework for video detection of active road users such as pedestrians at signalized intersections and (2) development of a means to convey the information on the presence of active users to both the signal controller (intersection management program) and drivers making use of a mobile application (via V2X communications).
