摘要
现代城市生活中交通拥堵是普遍存在的现象,本文针对车道占用对城市道路通行能力的影响问题,利用了视频和图片信息,使用微分方程和比较分析法等理论,分别建立了道路通行能力模型、车流量微分方程模型,利用Matlab等软件,得到了事故期间横断面实际通行能力的变化过程,估算了在一定条件下从事故发生开始到车辆排队到达上游路口的时间.
Traffic jam is common in everyday life in cities .Utilizing information of video and pictures , and taking advantage of knowledge of differential equation , comparative analysis and Matlab , Highway Capacity model and traffic flow differential equation model were established .Change of actual traffic capacity in cross -section during the accident was discussed and how long the vehicles can reach the upstream intersection from the spot under certain conditions was estimated .
