Traffic status analysis is the basis for highway management and control. Most of the previous research studies were carried out from the perspective of road segments. The purpose of this paper is to analyze the difference in traffic operation characteristics of an eight-lane highway from the perspective of lanes. Lane saturation, average lane speed, and lane density were selected as traffic state evaluation indicators, and the concept of state space division was introduced to classify the traffic operation status of each lane. Then, a single-system multi-index dynamic comprehensive evaluation method was adopted to reflect the time-varying characteristics and the development trend of the operation status of each lane. The research results can provide the theoretical support for more refined highway management and improve the service level of the eight-lane highway.

基于车道级的八车道交通状态动态评估

交通状态分析是高速公路管理和控制的基础。以前的大多数研究都是从路段的角度进行的。本文的目的是从车道的角度分析八车道高速公路的交通运营特性差异。选择车道饱和度,平均车道速度和车道密度作为交通状态评估指标,并引入状态空间划分的概念对每个车道的交通运营状态进行分类。然后,采用单系统多指标动态综合评价方法来反映各车道运行状态的时变特征和发展趋势。
