摘　　要：近年来,长三角地区频频高发的雾霾天气给高速公路交通安全带来的隐患引起了社会各界的关注。文章从交通环境和出行行为两个角度分析雾霾对交通道路安全的影响机理,并基于上海绕城高速(G1503)东南环浦星东主线的断面流量,从道路服务水平的视角,计量分析雾霾与交通道路安全的相关性。结果表明,雾霾会通过降低道路能见度,并通过影响驾驶员心理和改变出行者的出行方式增加道路拥堵的概率;进而导致道路服务水平降低,从而增加了交通道路安全隐患,但是该影响并非十分显著。In recent years,the frequent haze in the Yangtze River delta has brought hidden dangers to highway traffic safety.This paper analyzes the influence mechanism of haze on traffic road safety from the perspective of traffic environment and travel behavior.Based on the section flow of Shanghai circum-city expressway(G1503)in the southeast ring of Puxing eastern main line,the correlation between haze and traffic road safety was measured and analyzed from the perspective of road service level.The results show that haze can increase the probability of road congestion by reducing the road visibility,affecting drivers'psychology and changing the way travelers travel.This leads to the decrease of road service level and the increase of road safety hazards,but the impact is not very significant.
