摘要
随着城市"公交优先"理念的不断深入,有效协调多种公共交通方式间的竞合关系,对于充分发挥公共交通方式在城市居民出行中的主体作用具有十分重要的意义。采用MNL模型描述居民公共交通方式的选择行为,应用广义出行成本和主观感受建立效用函数,结合哈尔滨市地铁沿线居民出行数据,标定模型参数、验证模型有效性,并应用Matlab对模型进行仿真分析。结果表明:出行成本的单方面增加会损害自身的出行分担率;地铁和出租车分担率均与单位时间价值正相关;地铁分担率与平均出行距离正相关;出租车分担率与时间偏好系数正相关,地铁分担率与时间偏好系数呈抛物线变化。
With the concept of "bus priority" deepening, effectively coordinating the competition and coordination relationship of various public transport modes is of very significance to give full play the main role of public transport in residents travel. MNL model is used to describe the residents travel choice behavior, and the utility function is established with generalized travel costs and subjective feelings. Combined with Harbin residents travel data along the metro line, standardized model parameters, verified the effectiveness, this paper takes Matlab to simulate and analyze the above. The result shows that: the increase of travel cost one-sided will weaken its sharing rate;the sharing rate of taxi and metro has positive relation with the unit time value;the sharing rate of metro has positive relation with the average trip distance;that of taxi has positive relation with the time preference index, and that of metro has parabola relation with the time preference index.
