中文摘要：
为预测双核都市圈运输通道内旅客运输分担率,结合双核都市圈运输通道的旅客运输特性,通过将不同特性的变量引入效用函数,对Logit模型的应用加以改进,以成都-重庆运输通道为例,进行了旅客运输方式分担与线路分配的联合应用。结果表明：改进后的模型能有效地进行双核都市圈运输通道旅客运输方式分担与线路分配的预测;成渝（成都-重庆）运输通道中,成渝（成都-重庆）高速公路、成遂渝（成都-遂宁-重庆）高速公路、成遂渝（成都-遂宁-重庆）准高速铁路的分担率约为29%、33%、38%。
英文摘要：
In order to estimate the share rate transportation corridor, this paper unifies the of passenger flow in dual-nuclei metropolis passenger travel characteristics in dual-nuclei metropolis transportation corridor, improves to the application of Logit model by using function, so as to carries on the union application of mode share and line distribution. utility The improved model is applied to the Chengdu-Chongqing transportation corridor as an example. The results indicate that the improved model can estimate the passenger flow shares effectively. The share rate of Chendu-Chongqing freeway is 29%, the share rate of Chengdu-Suining-Chongqing freeway is 33%, the share rate of Chengdu-Suining-Chongqing raiway is 38%. 4 tabs, 9 refs.
