摘要
针对车道被占用对城市道路通行能力的影响,通过视频信息收集分析得到与道路通行能力相关的数据,使用Excel对数据进行处理,建立了道路通行能力模型,并分析了事故发生对道路的实际通行能力的影响,再推导出排队长度预测模型,使用控制变量法、微分法等方法得到交通事故所影响的路段车辆排队长度与事故横断面实际通行能力、事故持续时间、与路段上游车流量的关系,最后将模型结果与实际相结合,得到具体问题所求数据.
The traffic capacity model was built according to the influence of lane occupation and based on the analysis of the relevant data.The vehicle queue length model was deduced through evaluating the effects of accidents on actual traffic capacity.Then by using the control variables and differential method,the relationship among vehicle queue length,traffic capacity,traffic accident time and traffic flow was obtained.Finally,combining the theory of model with practice,the result of specific issues were gained.
