-Public Transport Service Evaluation and Optimization for a Super-aged Society using IC Card Data

对静冈的调查数据以及IC卡数据的出行频率数据的分析已基本完成。我们可以用这个“潜在的旅行”来建立公共汽车的使用和旅行的满意度。我们特别关注老化效应，因此将数据样本分为三组，非老年人（小于65岁），年轻老年人（65-74岁）和老年人（75岁以上）。以旅游满意度为因变量的回归分析显示了老年人旅游机会的重要性。然后，我们确定的相对重要性的流动性对生活质量的混合模型估计，并讨论交通政策的影响，老龄化社会的基础上，这些结果。研究结果表明，公交系统是65岁至74岁老年人潜在出行和出行满意度的决定因素，但对老年人的出行变量影响不显著。我们已经提交了一篇期刊论文，目前正在审查中。除了这一主要工作，我们进一步进行了两个相关的研究。首先，我们与一名硕士生一起研究了相同的IC数据，重点关注老年人随着时间的推移公交车使用量的减少。其次，我们根据韩国的数据发表了一篇关于公共交通设施满意度的论文。

The analysis of survey data from Shizuoka together with trip frequency data from IC card data has been largely completed. We could establish with this "Potential Travel" in terms of bus usage as well as travel satisfaction. We focused particularly on aging effects and therefore divide the data samples into three groups, non-elderly (less than 65 year), young elderly (65-74 years), and old elderly (over 75 years). Regression analysis with travel satisfaction as dependent variable show the importance of travel opportunity for older old. We then identify the relative importance of mobility on Quality of Life through a hybrid model estimation and discuss transport policy implications for an aging society based on these results. The results provide support that transit systems are determinants of potential travel and travel satisfaction of elderly between 65 and 74 years but that they do not significantly effect on both these travel variables in case of old elderly. We have submitted a journal paper which is currently under review.Besides this main work we further conducted two related studies. Firstly, with a Master student we looked into the same IC data with a focus on bus usage reduction over time of older people. Secondly, we published a paper regarding satisfaction with public transport facilities based on Korean data.
