摘要
介绍了城市交通尾气排放模型的特点,提出建立微观交通流与现有排放模型相结合的思想.把微观交通流中的优化速度模型与微观尾气排放模型结合起来,建立了基于微观交通流的城市道路微观尾气排放模型.用武汉市的观测数据对优化速度模型参数进行了辨识,对10辆车在十字交叉路口启动过程中的尾气排放进行了动态仿真,仿真结果表明该模型可以模拟城市交叉路口车队启动过程中尾气排放的动态演化过程.
The existent mobile emission model of urban is introduced. An idea about microscopic traffic flow model combining with mobile emission model is given. A hybrid microcosmic mobile emission model is built based on the optimal velocity model. Its coefficients are determined using traffic data of Wuhan city. The proposed model is applied to a case study of the emission progress of ten vehicles in an urban crossway. The simulating result shows that the model is effective for estimating second-by-second mobile emission.
