Abstrakt

Signalized intersections are the capacity-determining points on roads in cities, and the signal settings are usually based on very primitive algorithms which cause road users to experience a lot of unnecessary delay The work presented in this paper, show the effect of deploying a controller based on the optimization software Uppaal Stratego in four signalized intersections on the same road segment, the controller is fully distributed meaning there is no direct coordination between the intersections. The controller is tested against the controller deployed in the intersections today. 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.
