Abstract
Signalized intersections area a key area in the urban traffic networks, but the frequent stop-go behavior of vehicles makes the intersections congested. The paper firstly uses IDM (intelligent driver model) to analyze the string and local stability of the car following model, as well as the conditions for generating traffic oscillation at the signalized intersection. Secondly, we propose a two-layer harmonization optimal method, which guides connected vehicles with trigonometric functions and normal vehicles with IDM car-following model with the purpose of passing the signalized intersection without stopping and mitigating the traffic oscillation. The results of the MATLAB simulation indicate that the harmonization optimization method can effectively improve transit efficiency of the signalized intersection.
