摘要
针对目前多路相交的交叉口交通量调查工作存在的问题,提出了五路相交平面交叉口交通量调查的新方法。该调查法将人工观测车牌号法与数学理论推导相结合,利用各种车型的不同车牌尾号对五路交叉口各入口引道的车流进行随机抽样,以样本分析结果推算实际结果,先采用牌照法测定各入口引道进入交叉口的车型及牌照号码,然后再用数学理论推导的方式计算出车辆往各个方向的流量。最后通过实例证实了该方法的可行性。
Aiming at current problems of traffic flow investigation in multi-roads crossing intersection,this article introduces a new way to investigate traffic flow.This method combines car licence and mathematical theory and uses different numbers of all kinds of types to random sample the cars in each approach of five-roads crossing intersection.Then the practical result is calculated with sample-analysed result,which uses car license to determine car types and numbers in each approach and computes traffic flow towards every direction by mathematical theory.At last an example is put forward to prove this new idea is practicable.
