CS4VRU: A Centralized Cooperative Safety System for Vulnerable Road Users Using Heterogeneous Networks

Even though the number of accidents in the roads has decreased, the number of Vulnerable Road Users (VRUs) that are involved in these accidents are not following the same pattern. Thus, close attention should be paid to this group of road users. With this goal, this papers presents CS4VRU which is a cooperative application to be deployed in the frame of Smart Cities. The architecture of CS4VRU combines short and long range communication technologies in order to provide more time to the drivers and VRUs to take the appropriate maneuver and avoid a possible collision. The information generated by mobile sensors (vehicles and cyclists) is sent over this heterogeneous communication architecture and processed in a central server, which is in charge of generating the messages to aware the vehicles and bike bunch about the others.
