Characteristics of Trips and Travellers in Private and Public Transportation in the Danish Travel Survey data

This paper is motivated by a growing interest in providing greater insight into the travel habits of Danish travellers. The analysis is conducted on the data collected in the Danish Travel Survey (in Danish: Transportvaneundersøgelsen, TU) from 2006 to 2009. The investigation of these data enables pointing out which travellers’ and trips’ characteristics to pay special attention to when examining the choice between private and public transportation. This is important for the future estimation of mode choice and public route choice models, but also for the general knowledge about which issues should be taken into account when trying to improve the conditions for public transport users and which initiatives could convince more people to travel by public transport. The analyses show that income is very important for the choice between public and private transportation since income also reflects gender, place of resident, etc.

本研究的研究动因源于学界对深入洞察丹麦旅行者出行习惯的日益浓厚的兴趣。本次分析基于2006年至2009年间丹麦出行调查（Danish Travel Survey，丹麦语名称为Transportvaneundersøgelsen，缩写TU）所采集的数据开展。对该数据集的分析能够明确，在研判私人交通与公共交通的出行方式选择时，需重点关注哪些旅行者个体特征与出行行为特征。这一研究成果不仅可为未来出行方式选择模型与公共交通线路选择模型的参数估计提供重要支撑，还可为相关通用研究积累知识储备：即在优化公共交通使用者的出行条件时应考量哪些要素，以及可通过哪些举措吸引更多民众选择公共交通出行。分析结果表明，收入水平对公共交通与私人交通的出行方式选择影响显著，这是由于收入水平同时也与性别、居住地等因素存在关联。
