无控制交叉口车辆延误影响因素分析

Influence factors on delay in unsignalized intersection

摘要:

研究无控制交叉口车辆延误对于改善交叉口的交通秩序及提供有效的管理有重要意义.论文分析了无控制交叉口延误产生的过程,设计了延误的调查方案,通过对哈尔滨市典型无控制交叉口的调查,对交通条件中的交通量、冲突流量、流量分布、流向构成、车型比例5种因素与延误的关系进行了研究,通过实测数据散点图的变化分析了各种因素对延误的影响.论文研究可以加强对无控制交叉口车辆延误的分析与判断,并为无控制交叉口车辆延误的计算提供理论依据.

Abstract:

Research on delay in unsignalized intersection can improve the level of traffic regulations and management of intersections effectively.This article presents the process how delay happens in an unsignalized intersection and gives the investigation plan.Combined with survey results in Harbin,the relationship among traffic flow,traffic conflict,flow distribution,flow structure and the proportion of vehicles is studied.Then,the factors on the delay can be found through the change in scatter diagrams of investigation data.This research can provide the planners with an efficient analysis on the delay and provides a theoretical foundation for the calculation of delay in unsignalized intersection.
