In current vehicle to vehicle (V2V) communication systems, each vehicle broadcasts its motion status and receives information from other vehicles in order to make safety decisions and actions. State-of-the-art pre-collision systems (PCS) utilize onboard sensors to collect potential crash object information for making safety action decisions. This V2V-PCS combination enables a vehicle to not only send its own motion information, but also its PCS detected information to other vehicles. Conceptually, the additional information should help a V2V enabled vehicle make its safety related decisions more accurately and efficiently. The objective of this study is to find if a combined V2V and PCS system (V2V-PCS) can further improve the safety of not only V2V-PCS enabled vehicles but also other non V2V-PCS enabled vehicles on the road. This paper describes a process that can be used to analyze pedestrian and vehicle scenarios, and determine whether or not the safety of pedestrians could be improved by a V2V-PCS system. It also gives an analytical method for determining the benefit of using V2V-PCS. The environments set up for V2VPCS simulation and real vehicle testing are also described.
