多层LOGIT模型的理论分析研究

Theoretical Analysis of Nest Logit Model

合理有效地调整城市各种交通方式分担率以改变城市交通结构已经成为解决城市交通拥堵的有效方法。非集计模型的发展促进了交通方式分担的较大进步,对个人交通行为的分析研究是交通需求预测的一种比较重要的方法。在简述非集计模型发展的基础上,重点推导NL模型以及运用TransCAD对NL模型的参数进行标定,为非集计模型的应用和提高其操作性提供了思路。

With the continuous economic development,urban vehicle with a large volume by the ratio of polyethylene,the increasingly severe urban traffic congestion.Reasonable and effective to adjust a variety of transport means the city contribution rate to change the structure of urban transportation has become a solution to urban traffic congestion is an effective method.Non-collection of the development model promoted greater sharing traffic the way the progress of the individual analysis of the traffic study projected traffic demand is a more important way.In this paper,the model of non-collection of the development of a brief,focusing on NL model derivation and use of the NL model Transcad calibration parameters for non-collection of model and enhance its interoperability with a train of thought.
