Simulation on Vehicle Emission by the Brake-Light Cellular Automata Model
Abstract
Vehicle emission has become a major source of air pollution. In this paper, the brake-light cellular automaton model incorporated with a vehicle emission model is utilized to investigate emitted exhaust pollution by traffic flow. First, both macro- and microscopic features of traffic flow are reproduced quantitatively and compared with empirical findings. Then the model is used to simulate the vehicle emission of a moving fleet of vehicles. It is shown qualitatively that the emission rate is significantly increased in the medium density range with considering instantaneous velocity and acceleration together. Usually the total amount of pollutant discharge from vehicles is underestimated by considering average velocity alone. It is believed that a good driving strategy, e.g. eco-driving, is an effective way to reduce vehicle emission.
