【摘要】 运用模拟的方法，对主路优先交叉口的通行能力进行了研究，从微观的角度对影响通行能力的各关键参数进行了新的标定，并建立了基本模型．该方法的特点是面向对象，它保证了交叉口中各种交通特性都能在模型中得到真实的反映，而且在同等条件下，模拟的结果与经典公式的结果拟合程度很好．最后，本文还提出了标准车型单位（小客车当量）的换算方法．模拟方法还适用于支路车辆延误的分析研究．更多还原

【Abstract】 Several key parameters affecting the traffic capacity are re demarcated,and the basic model is presented. It is an object oriented method, which ensures that various traffic and driver behavior characteristics fed into the model are realistic.The result of simulation is basically consistent with that of classic formulae under the same condition.Finally,the method to determine the convertible coefficient of the passenger car unit is provided.The method also fits the problem about delay of minor stream.更多还原
