摘要:
以交叉口运行效率为目标,运用概率论、排队论和交通流理论对无信号交叉口左转车道的设置依据进行研究.设车流到达率服从泊松分布,根据左转与直行车辆的相互作用过程和运行特性,推导无信号交叉口左转车道设置的左转交通量阈值表达式,并讨论模型中的参数:受左转影响的直行车停车概率的限值、左转穿越对向车流的临界间隙和进口道车道数.对典型情况进行模拟计算,绘制了左转车道设置的准则图表.计算分析得出无信号交叉口设置左转车道左转交通量的变化规律.为左转车道的设置提供了定量化的依据.
Abstract:
Treatments of left-turn are the most difficult problem at intersections.Left-turn lane guidelines for unsignalized intersections were studied using probability theory,the theory of queue and traffic flow theory.The study objective is operation efficiency.The interaction between left-turn vehicles and through vehicles and operation characteristics were analyzed.The equation of left-turn threshold volume for left-turn lane installation at unsignalized intersections was derived.The traffic flow arrival rate was supposed as Poisson distribution.Parameters were discussed.The first is the stop probability of through vehicles influenced by left-turn vehicles;the second is the critical gap and the third is approach lane number.Simulations were done for the general conditions.Tables and figures of left-turn lane warrants for unsignalized intersections were established.Variation laws of left-turn threshold volume for left-turn lane installation were obtained by analyzing the calculation result.Numerical guidelines for left-turn lane installation at unsignalized intersections were obtained.
