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%.
