摘要：

雾霾对城市交通路网的影响主要包括交通数据缺失、交通安全和污染物排放三大问题.首先,基于城市交通数据监测系统，增加路网模型中驾驶员对能见度因素的反应特性，建立雾霾情况下交通路网模型，包括车道模型和交叉口模型两部分.然后，建立雾霾情况下交通路网模型评价指标,包括路网交通数据缺失率、交通危险系数和路网车辆污染物排放指标.最后，通过雾霾对路网影响程度和影响区域的仿真，得出如下结果：雾霾程度越严重、影响区域范围越大，交通数据缺失率越高，越不利于交通安全，同时污染物排放越多.

Abstract:

Haze causes three major problems to urban traffic networks: missing traffic data, unsafe traffic and pollutant emissions. Firstly, driver reaction characteristics on visibility factors are increased and road network models in haze are established (the lane model and intersection model) by using urban traffic data monitoring systems. Moreover, the evaluation index of the traffic network model in haze includes traffic data loss rate, traffic dangerous coefficient and vehicle pollution emission index. Finally, by simulating the degree of haze influence and the regions of road networks, the simulation results are compared. Results show that more serious degree of haze influence and a larger road network range correspond to more serious haze impact. A greater haze impact on the road network leads to higher rate of traffic data loss, lower degree of traffic safety and higher emission of pollutants.

Key words: traffic engineering, road network model in haze, haze situation influence on road network evaluation index, road network model simulation
