| Abstract: | The automotive exhaust emission will do harm to people's health and destroy the ecological balance.A bi-level optimization model with user-equilibrium route choice was proposed to optimize the signal cycle length and green time by considering the constraint of automotive exhaust emission.The performance index function for optimization is defined to improve traffic quality and reduce emission at intersections.At the same time,its heuristic genetic algorithm and solution with the aid of GA tool of Matlab are ... |
