This paper provides an overview of several favourable approaches and solutions for infrastructure support of automated vehicles. Two inherent generic goals for this are to increase traffic efficiency and to enhance traffic safety. For efficiency, there are several measures that can be taken with a traffic light controller. An already established service for cooperative vehicles is Green Light Optimal Speed Advice (GLOSA). This service gives a speed advice to approaching vehicles that prevents them from stopping at the intersection. With automated vehicles, the potential of this service can be further increased due to the higher precision with which instructions can be provided and executed. However, it is also widely known that dynamic behaviour of traffic light control algorithms can deteriorate the impact of the GLOSA service and in some cases even make the service harmful.
