An Optimization Model of Short Lanes at Intersections Based on Vehicle Specific Power

To reduce delays and traffic emissions at intersections, the operating characteristics of intersections acquired by VISSIM, a method of calibrating emission factors during signal at intersection, is proposed on basis of VSP. Combined with operations research and traffic engineering theory, an optimization model of short lane length is established. The objectives of the model are to minimize vehicle delays and emissions. Considering pollutants of CO, HC, and NOx in car exhaust, simulation experiments are designed by VISSIM. Considering the vehicle data, the algorithms of calibrating the model parameters and solving the optimization models are programmed and calibrated by MATLAB. The results show the optimal length makes the average delay and traffic emissions decrease by 11% and 6.7%, respectively. The research can effectively decrease vehicle delays, reduce emissions at intersections, and provide a theory for intersection design and channelization optimization model connected with traffic emission.
