Reducing vehicle exhaust gases by computer simulation of the road intersection

This article presents the results of developing an intersection model using the PTV VISSIM simulation program. One of the problematic intersections in the city of Tashkent was selected and the traffic flow at peak hours according to congestion was studied to simulate the intersection. The article discusses two solutions to reduce the amount of toxic gases and fuel consumption. The first solution represents a reduction through the optimization of traffic light phases and a change in the junction control cycle. The second solution represents the reduction through changes in the geometrical parameters of the intersection. After applying the two solutions, the level of service LOS at the intersection improved from F to B.
