Congestion Control -- Queue Warning, Variable Speed Limits and Link Control Systems in Sweden

This paper discusses different systems to manage congestion on motorways into and through city areas. Deployment and experienced traffic impacts of queue warning systems, Variable Mandatory Speed Limits (VSL) and Link control systems in Sweden are presented. An implementation strategy when traffic is raising and queuing problems are growing is proposed. The main area for Variable mandatory speed limits seems to be to manage congestion and growing queues especially where the speeds tend to suddenly fall dramatically. This is especially valid on busy arterials with recurring capacity and traffic safety problems. Sections that are curvy, hilly and have road passages breaking the sight line would be suitable candidates for VSL.
