In Uppaal Stratego for Intelligent Traffic Lights, Eriksen et. al. showed that there is a great optimization potential in using better control algorithms, which optimize the traffic flow based on the radar inputs for a single isolated crossing. The work presented in this paper, show the effect of deploying a similar controller in four signal-controlled intersections on the same road segment, our controller is fully distributed meaning there is no direct coordination between the intersections. Our controller is tested against the real controller deployed in the intersections, currently three of the intersections are coordinated and the last one is traffic controlled. The controllers have been tested using the micro simulation program VISSIM. The simulation shows that in comparison with the existing controller, this controller provides a reduction of between 30% and 50% in average delays, queues and number of stops. The fuel consumption and total travel time of cars in the coordinated section are reduced by about 20% in the simulation study. All these reductions are achieved without making the situation worse for the side roads.
