摘　　要：为探究城市轨道交通换乘常规公交的时间优化模型,以上海市晚高峰时段地铁6号线金桥站换乘874线路公交车为例,利用统计分析软件,分析客流到站时间,得到对数正态分布;并在此基础上建立乘客候车时间模型,运用调查所得数据设置模型各参数值;最后以乘客候车时间最少为目标函数,利用遗传算法求解得到874线路公交车优化后的到站时间.结果表明:利用时间优化模型求得的874线路公交车发车时间与优化前的发车时间相比,乘客的候车时间平均每人节约约52.8 s,有效提高了人们的出行效率.To explore time optimization model for transfer from rail transit to buses, the arrival times of passengers were analyzed and its logarithmic normal distribution was obtained using statistical analysis software taking the example of Jinqiao station of metro line 6 transfers to route 874 buses during evening rush hour in Shanghai, and then the passengers waiting time model was established whose parameter values were established according to the survey data, finally the optimized arrival times of route 874 buses were received by genetic algorithm taking minimum waiting time of passengers as the objective function. The results show that the passengers waiting time which achieved by time optimization model is saved about 52.8 s compared with data by non-optimized model, and the travel efficiency of people are improved.
