Traffic-light cycle coordinated by microsimulation: a solution to the traffic congestion in Palermo

摘要

This article aims to highlight the results of an analysis of the traffic management carried out by the Department of Civil Engineering of the University of Palermo, through traffic microsimulation model and matematical calculations. In order to demonstrate the usefulness of a coordinated traffic light cycle, in presence of an area of Palermo of high traffic flow. We used microsimulation for planning traffic lights, calculating mathematically the phases in traffic lights and doing changes in the geometry of the intersection. Although this approach is not new, we would like to emphasize the importance of the use of microsimulation models in urban planning of medium-sized cities such as Palermo, characterized by a high rate of traffic congestion.
