Travel behavior analysis using the fractal dimension of states as indices expressing the influence on one worker from other personnel

状态分维是一种量化某一确定区域内点的分布状况的方法，它提供了工作场所和居民区在工人中分布的数值表达式。本研究以一种状态的分维作为指标，来表达工作场所中其他人员对一名工人的影响。这些被引入一个分类模型来分析工人通勤时的交通行为。基于分维的模型在精度和复相关系数方面提供了最优值。此外，除了随着服务水平的变化和城市政策的制定而改变交通工具的人数的变化外，本研究提出的模型还表明了政策之后的变化。

The fractal dimension of states is a method for quantifying the condition of distribution of points within some defined region, and provides a numerical expression of the distributions of the workplace and residential area among workers. This study employs fractal dimensions of a state as indices expressing the influence on one worker from other personnel in a workplace. These were introduced into a disaggregated model to analyze the transportation behavior of workers while commuting to work. The models based on fractal dimensions provided the best values in terms of accuracy and multiple correlation coefficient. Also, in addition to variations in the number of people changing their means of transportation response to changes in service levels and in the enactment of city policies, the model proposed in this study also indicates changes subsequent to the policies.
