The purpose of this chapter is to introduce various initiatives related to developing an overall system architecture for Cooperative Intelligent Transportation Systems (C -ITS). C -ITS is also often programmatically referred to in North America as 'Connected Vehicles (CVs)'. Regardless of terminology, C -ITS is focused upon the following forms of connectivity: Vehicle -to -Infrastructure (V21) communications - Tying vehicles to roadside systems, in particular those components owned and operated by local or state transport departments and authorities or private road operators. V2I data can support local transport systems management and operations activities for improving mobility, safety, and environment. V2I can support real-time traffic control as well as tolling, pricing, and payment services, and the data can be highly beneficial to transportation performance analytics, providing transport operators with an assessment of how their current strategies are performing over various time -based, daily, or seasonal condition
