| 摘 要： | 以可接受间隙理论为基础，利用概率分析方法，对由多种车型组成的混合车流进行了分析，在无控交叉口主路车流车头时距服从二阶Erlang分布条件下，建立了支路多车型混合车流的通行能力模型，发展了无控交叉口的混合车流通行能力理论，通过实例分析，并与其他模型比较，本模型计算结果更接近实际情况，相对误差只有16．6％。

| Abstract: | Based on the gap acceptance theory, the mixed traffic flow was analyzed with probability method. When the flow at major lane of unsignalized intersection follows two-class Erlang dis-tribution, the traffic capacity model of mixed flow at branch lane was developed. With an exam-ple, its calculation results were compared with the ones by other models. The results indicate that this model is more accurate, its error is 16.6%. 3 tabs,9 refs. |
