With a long history, traffic controllers have great impact in our lives. In this chapter, we review five critical components in controlling traffic. We show that how different elements of these components can affect the traffic systems. Also, we present a quick review on mobility models, from communication engineers' and traffic engineers' perspectives. We show how these views are different from each other's. Intelligent transportation system (ITS) and its presence in the traffic controllers are the next topic of this chapter. Architecture of macroscopic and microscopic traffic controllers is explained too. Finally, we review the current issues in collaboration between VANET and traffic controllers before the conclusion of the chapter. The reviewed issues are deploying VANET infrastructures and using VANET-based P2P networks in traffic information systems.
