摘要
研究了在雾霾天气影响下,采用一型模糊集理论将不同能见度下的危险性指数引入到雾霾天气不同能见度条件下的单车道交通流微观模型,通过一定的实验模拟,得到了对应的时空图,并进一步对速度-密度交通流特性以及速度-时间交通流特性进行了分析。研究结果对于分析雾霾天气下道路交通流机理,对交通管理和控制方面具有一定的应用价值和意义。
Under the influence of smog weather,the risk index under different visibility is introduced into the microscopic model of single lane traffic flow under different visibility conditions by using one type fuzzy set theory.Through certain experimental simulation,the corresponding time-space diagram is obtained,and the speed density traffic flow characteristics and speed time traffic flow characteristics are further analyzed.The research results have certain application value and significance for analyzing the mechanism of road traffic flow under haze weather and for traffic management and control.
