16 VIDBE-Q Volume 63 Issue 4 pedestrian route information to allow the signal system to anticipate pedestrian arrival at the intersection and reduce pedestrian wait time. Finally, the app will use real-time information of approaching buses being communicated to the signal system to facilitate the pedestrian's timely arrival at the bus stop to meet the bus that the pedestrian is trying to catch. Technical Approach The technical approach taken to provide these capabilities combines emerging connected vehicle technology, specifically the use of Dedicated Short Range Communication (DSRC) radios, with recent advances in real-time, adaptive traffic signal control, embodied in the surtrac traffic signal control system. The basic components of the PedPal solution are illustrated in Figure 1 below. DSRC communication technology, the first element of our approach, has been projected as the future basis for vehicle-to-infrastructure (V2I) communication, and DSRC radios are already available in selected 2018 production models of vehicles sold in the US. It promises to provide much greater visibility of approaching vehicles to the intersection than is possible with current vehicle detection technology. From the perspective of pedestrian travel, DSRC provides a uniform communication framework for gaining access to real-time vehicle information as well as a means for the pedestrian to interact directly with the intersection.
