This study investigates the influence of transport infrastructure, income inequality, information and communication technology on transport-oriented household expenditures. For this purpose, we chose the data set period from 1997 to 2021 for the 24 OECD countries and employed the cross-sectional auto-regressive distributed lagged (CS-ARDL) approach. Therefore, the outcomes reveal that income inequality drastically upsurges transport-oriented household expenditures, especially the pre-tax income share of the 100th percentile concentration of the super-rich. Besides, there is a convex relationship between income inequality and household expenditures. The magnitudes of information and communication technology (ICT) are negative and significant, implying that ICT reduces transport-related household expenditures by allowing them to access real-time information and choose their destination as well as travel modes from the comfort of their own homes. Also, the combined effect of income inequality and ICT reduces transport-related household expenditures in the sample countries. Thus, the findings recommend some policy implications and direct future research directions based on empirical evidence.

本研究调查了交通基础设施、收入不平等、信息和通信技术对交通导向型家庭支出的影响。为此，我们选择 24 个 OECD 国家的数据集时期为 1997 年至 2021 年，并采用横截面自回归分布滞后（CS-ARDL）方法。因此，结果表明，收入不平等急剧增加了以交通为导向的家庭支出，尤其是超级富豪集中在第100个百分位数的税前收入份额。此外，收入不平等与家庭支出之间存在凸关系。信息和通信技术（ICT）的重要性是负面的和显着的，这意味着ICT允许人们在舒适的家中获取实时信息并选择目的地以及出行方式，从而减少了与交通相关的家庭支出。此外，收入不平等和信息通信技术的综合影响减少了样本国家与交通相关的家庭支出。因此，研究结果基于经验证据提出了一些政策含义并指导了未来的研究方向。
