一种城市交通瓶颈的计算方法

Method for calculating urban traffic bottlenecks

城市交通瓶颈指的是常发性拥堵路段或位置。以往基于交警的巡查经验来确定交通瓶颈,虽可以部分地反映实际情况,但成本太高且无法做到动态跟踪。运用交通传感数据提出了一个简单的交通瓶颈计算方法,通过计算统计周期内的路段拥堵概率来反映交通瓶颈的严重程度。实验表明该方法是有效的。

Traffic bottlenecks refer to road segments or locations with frequent traffic jams. Traditional methods for evaluating traffic bottlenecks are mainly based on patrol experience, which could partly work but is costly and cannot dynamically track the change of bottlenecks. This paper proposed a simple method that evaluates bottlenecks by ＇using the congestion probabilities of road segments obtained from the analysis of traffic sensing data. The experimental results show the effectiveness of the proposed method.
