基于实时路况数据的拥堵评价方法研究
|
摘要
针对现有的交通拥堵评价方法均值法存在对拥堵变化不敏感的情况,提出了基于实时路况数据的拥堵占比率评价指标。首先采用GIS分析处理软件对实时路况数据进行分类提取路况信息,根据路况变化分级值判断某时段内各道路的变化状态。以南京市五个工作日内不同时段的路况数据为基础,计算道路趋向于拥堵变化状态下的拥堵占比率。根据计算结果,分析评价了南京工作日内拥堵路段的时空分布特征,并提出了可行的避堵、缓堵建议。给出的评价方法可在城市交通运行分析、道路拥堵变化分析中应用。
In view of the fact that the mean method is not sensitive to road congestion changes for the existing traffic evaluation methods,this study proposes a congestion ratio evaluation index based on real-time traffic condition data.Firstly,the GIS analysis and processing software was used to classify the traffic information of the real-time road condition data,and the change state of each road in a certain period of time was evaluated according to the classification value of the road condition change.Based on the traffic data of different working periods in five working days in Nanjing,the ratio of congestion to traffic congestion was calculated.According to the calculation results,the spatial and temporal distribution characteristics of congested roads in Nanjing working days were analyzed and evaluated,and some feasible suggestions for avoiding blockage and slow blocking were put forward.It maintains that the evaluation method can be applied to urban traffic operation analysis and road congestion change analysis.
