Intelligent transportation systems have been under development since at least the early 1990s. The rationale behind the concept is to automate the interactions among vehicles and infrastructure to achieve high levels of security, comfort, and efficiency. Communications, in general, and networking, in particular, have been essential elements in the evolution of these systems. The IEEE has developed a system architecture known as WAVE to provide wireless access in vehicular environments. This article gives an overview of the associated standards. The presentation loosely follows the order of the layers of the open systems interconnection model.
