| 摘 要： | 为了解决信号交叉口右转机动车受自行车干扰严重的问题,运用间隙理论和车流波动理论研究干扰环境下右转机动车的通过数量,以度量混合交通环境下右转机动车的通行能力。在分析大量调研数据的基础上,探讨了无信号控制的右转机动车和自行车在二相位信号控制交叉口运行的微观行为,提出了混合交通环境下信号交叉口右转机动车的通行能力模型,结合典型路口对该模型的有效性进行了验证,并开展了右转机动车通行能力相对于自行车流量的灵敏度分析。结果表明:当自行车到达量在500~1500 bic.h-1情况下,自行车到达量的变动对右转机动车通行能力的影响较大。

| Abstract: | In view of the serious interference between right-turn motor vehicles and bicycles at signalized intersection in China,in order to measure the capacity of right-turn vehicles effectively under mixed traffic,authors studied the passage number of right-turn vehicles by use of traffic flow wave and gap theory under interference environment.Based on the analysis of a large number of research data,authors discussed the micro-operation of right-turn motor vehicles and bicycles,and proposed the model for calculati... |
