INFLUENCE OF TRAFFIC LIGHT CONTROL LOGIC ON VEHICLE EXHAUST GAS EMISSIONS

An objective social process is an increase in the number of cars, which complicates the envi-ronmental situation in cities. The formation of toxic substances in exhaust gases is closely related to the processes of fuel oxidation and engine operating modes, which are dependent on the mode of movement of cars. The analysis of the influence of the method used to control traffic signals on exhaust gas emissions was performed using a microscopic simulation model. We compared the use of pre-calculated traffic light signals with adaptive control in real intersection conditions, taking into account the dynamics of transport demand. The conditions under which the use of adaptive control of traffic lights signals can significantly reduce the volume of exhaust gas emissions of cars are identified.
