Gainesville Bike and Pedestrian Safety Project

Project Description: Federal Accelerated Innovation Deployment (AID) program project to test and implement connected vehicle and pedestrian/bicyclist safety applications (active or passive) at 13 signalized intersections and 8 mid–block crossings within the core of the University of Florida (UF) campus. The goal of this project is to reduce pedestrian and bicycle crashes and conflicts with vehicles and transit. The routes are SR 26 (University Avenue), US 441 (SW 13th Street), Museum Road, and Gale Lemerand Drive. The project will install roadside units (RSUs), passive pedestrian detection systems, on–board units, and rectangular rapid flashing beacons.

The following will be tested during this project:
– Passive pedestrian/bicyclist detection at all locations via detection technologies.
– Real–time notification to transit, motorists, and pedestrians/bicyclists.
– Signal phase and timing data broadcasting with active pedestrian/bicyclist detection via RSUs.
