With many trials having been held in the past decade, the time frame for the roll out of dedicated V2V and V2I ITS infrastructure remains uncertain despite the possibility of mandates in countries such as the US. With the success of V2V and V2I technologies largely depending on their high penetration into vehicles and roadside infrastructure, existing connectivity solutions such as cellular and Wi-Fi will play an important role as proxies in terms of bridging the time, penetration, and cost gap. This study explains how dedicated ITS infrastructure will be complemented by active safety (ADAS) and converged connected car technology. It includes descriptions of major standards, government mandates, and industrial initiatives, as well as system shipment forecasts for the 3 categories of connected car technologies.
