基于决策树的居民出行模式分析

Analysis of Travel Patterns based on Decision Tree Models

以印度尼西亚首都雅加达都市圈的居民出行调查数据为例,从两方面进行研究:一是研究居民对辅助公共交通的使用情况,二是研究居民对出行模式选择的问题,并对两个子问题分别建立了两个决策树模型.研究结果确定了两个模型的重要影响因素,并进一步探讨了决策树各节点划分的规律,即揭示了上述各种影响因素的作用规律.

To promote reasonable change of urban transportation structure, two aspects are focused by employing personal trip data in Jabodetabek metropolitan area, Indonesia. One is studying the usage of the paratransit,and the other is studying citizen travel patterns. Further,two decision tree models are built based on the above-mentioned aspects. The research results indicate the most significant factors to the two models, and explore the rules of the split value of decision tree nodes,i. e. ,uncovering the rules of the above-mentioned influencing factors.
