Cooperative systems exploit potential beyond conventional intelligent transportation systems. Development and research concerning such systems in urban areas mainly focus on signalized intersections. Cooperative systems can act to influence the signalization, the drivers, or a combination of both signalization and drivers. In this article, selected national and European research efforts are presented that aim at incurring both a raise of traffic efficiency and traffic safety. Subsequently, areas for future research are introduced, including requirements for the enhancement of existing or the development of new signal control systems, the change in driving behaviour due to the usage of cooperative systems and the consideration of further diversifying types of vehicles and propulsion systems.     «
