摘要:

为了揭示临时变向车道所存在的交通运行问题,针对其方向变更时段的交通流速度特性与交通冲突特性进行分析.选择具有代表性意义的黄浦路为调查对象,分别对其方向变更前后的交通流特性参数进行调查.采用数理统计的方法,对比分析方向变更前后的交通流速度特性与交通冲突特性.采用回归分析的方法,构建该类车道的密度与速度关系模型及交通冲突预测模型.研究表明,临时变向车道在方向变更前后的交通流速度及交通冲突方面具有明显的规律性差异,速度与密度之间及冲突数与流量、密度之间存在定量关系.

Abstract:

In order to reveal the existing traffic operation problems of temporary reversible lane, the characteristics of traffic flow speed and traffic conflict in period of direction changing are analyzed. Selecting Huangpu road with representative significance as the investigation object, the characteristic parameters of traffic flow before and after direction changing are investigated respectively. By mean of mathematical statistics, the characteristics of traffic flow speed and traffic conflict before and after direction changing are compared and analyzed. Using method of regression analysis, not only the relationship model between speed and density is constructed, but also the prediction model of traffic conflict is proposed. The research indicates that, in terms of traffic flow speed and traffic conflict of temporary reversible lane, there are obvious and regular differences between them before and after direction changing. There is a quantitative relationship between the speed and density. The relationship among the quantity of traffic conflict, volume and density also exists.

Key words: urban traffic, traffic conflict, regression analysis, temporary reversible lane, traffic flow speed
