通行规则对道路状况的影响分析

针对通行规则对不同道路状况的影响问题,使用非线性拟合、相关性分析、碰撞临界值法等方法,分别建立了等速超车模型、变速超车模型、变道临界距离模型等模型,计算得到了在右行通行规则下,不同的道路负荷。分析了不同的道路通行规则对驾驶员的反应时间、车道变道时间的影响,通过智能系统模拟计算得到车辆在发生碰撞临界条件下的最小行车距离。

Effects of Traffic Rules on Road Conditions

Based on the traffic rules influencing traffic conditions , the following research methods and models are proposed, such as nonlinear fitting, correlation analysis, the critical value collision, constant overtaking model, variable speed overtaking model, lane changing direction comparison model, and the threshold distance of lane change model.With the help of the software programming (Matlab, Excel, etc.), the author draws the following conclusions: different load would make the traffic volume, accident rate, and lane changing time different under the rules of vehicles driving on the right; when comparing different traffic rules, according to different response time lane changing time is different.By simulating the vehicle change lanes in the intelligent system, we calculate the minimum driving distance, which is the critical condition of vehicle collision.
