Collision Avoidance Systems (CAS) have the potential for improving transportation system safety including the safety of transit vehicles and pedestrians. Recognizing the importance of improving the safety performance of transit services, FDOT in collaboration with the MiamiDade County Public Work Department has initiated this research project to evaluate the effectiveness of Mobileye Collision Avoidance Systems (CAS) technologies in addressing transit vehicle-pedestrian and rear-end conflicts and the associated safety problem. The technologies have been tested on Miami-Dade County bus routes with the goal of helping agencies in Florida and around the nation in making decisions regarding investment in CAS technologies, considering the safety effectiveness of these technologies.
