摘要:为拟合拥堵状态下通行能力降低的特性,对拥堵状态下单行信号控制交叉口的通行能
力计算方法进行了优化。首先,研究了停车线法、HCM 法与规范法在计算通行能力的不足,
并在此基础上建立了基于 HCM 通行能力模型和停车线法的综合计算模型;其次,通过实地
调查采集了拥堵状态下单行信号控制交叉口的实际通行能力值,并在此基础上对停车线法、
HCM 法、综合法进行了对比分析。计算结果表明:综合法计算得到的进口道通行能力值与
实测值的相对误差均小于 5%,优于现有的通行能力计算方法。

Abstract: In order to matching the capacity-reduce characteristic in condition of congestion, this
paper optimized the mathod of calclulating the capacity of signal intersection under one-way
management in this status. Firtsly, studied the shortages of exsiting capacity calclulating methods,
. stop line method, HCM method and specification-based method, on the basis of wich,
proposed a synthetic bining HCM method with stop line method. Secondly, compared
the actual capacity values obtained by investigation at two intersecitons with the calcluated values.
The results shows that the synthetic method perfroms more superiorly than other methods for the
relative error within 5%.(10 Points, Times New Roman)
