摘　　要：利用TSIS微观交通仿真软件对长春市工农广场交叉口的交通运行状况、排放情况进行了仿真模拟,提出了两个以排放为主要评价指标的信号配时优化方案,以延误作为辅助验证指标,分别进行了对比分析,从排放角度确定了最佳的信号配时优化方案。该方法为城市道路交叉口信号配时优化中如何考虑排放问题提供一种新思路。It is well-known that the urban road intersection is the area of the most polluted by the vehicle emissions, so taking Gongnong square of Changchun City as an example, its traffic and emission status was simulated by the microscopic simulation software TSIS. The vehicle emission was selected as the main test criterion and the vehicle delay as complementary criterion, two signal timing optimization concepts were proposed and comparatively analyzed, and an optimal concept was defined. The obtained results provide a new approach to reducing the vehicle emission on the urban road intersection by the signal timing optinization.
