Connected vehicle technology has the potential to improve safety and mobility for local and wide-area traffic management. Most previous studies of connected vehicle applications have used simple and hypothetical networks; measurements in realistic and large networks are required if connected vehicle applications are to be deployed in the real world. This paper measures the performance of vehicle-to-vehicle (V2V) applications and determines the required minimum level of deployment for V2V applications in a large urban network. Distance of information propagation and speed estimation error are used to measure the performance of event-driven and periodic applications with different market penetration rates of equipped vehicles and wireless communication coverage, at both morning peak and non-peak times. As wireless communication coverage and market penetration rates of equipped vehicles increase, distance of information propagation increases while speed estimation error decreases in the study area. For event-driven applications, wireless communication coverage is the major factor because it has a greater impact on the distance of information propagation. For periodic applications, however, the market penetration rate of equipped vehicles has a greater impact on performance than wireless communication coverage; this is because the speed estimation error more decreases as the market penetration rate increases. The performances of both event-driven and periodic applications improve in the higher traffic volume conditions that occur in peak time. The required minimum level of deployment for each application is determined to obtain reliable traffic management solutions. These study findings will be useful for deployments of connected vehicle applications. In particular, event-driven applications can be deployed reliably in the initial stage of deployment, despite their low level of market penetration.
