分析了F-B配时方法延误计算模型的缺陷.证明了上海配时方法的结果是各个相位的饱和度为1.建立了延误-通行能力联合优化配时模型,以延误与通行能力之比最小为优化目标.应用分析表明:F-B配时方法使车均延误比现状减少了1.65s;上海配时方法使车均延误减少了8.15s,但通行能力降低了422pcu/h;联合优化配时法使车均延误减少了9.46s,通行能力保持了现状水平. The shortcomings of the delay calculation model of FB timing method are analyzed.It is proved that the result of Shanghai timing method is that the saturation of each phase is 1. The joint delay-throughput optimization timing model is established, and the ratio of delay to throughput is the minimum Optimization objective.Application analysis shows that: the FB time-delay method reduces the vehicle delay by 1.65s compared with the current situation; Shanghai time-delay method reduces the vehicle delay by 8.15s, but reduces the traffic capacity by 422pcu / h; Vehicle delays were reduced by 9.46s, the capacity to maintain the status quo.
