摘要

本研究探讨了影响家庭车辆行驶里程(VMT)的因素,重点关注电动汽车(EV)与传统内燃机汽车(ICEV)之间的差异。本研究主要利用 2017 年全国住户出行调查-加州附加调查(2017 NHTS-CA)中详细的个人层面数据。我们首先将家庭分为三组,如(1)只拥有内燃机汽车的家庭;(2)只拥有电动汽车的家庭;(3)同时拥有内燃机汽车和电动汽车的家庭。然后,我们采用普通最小二乘法回归模型分析三组家庭 VMT 的决定因素。其次,我们以同时拥有内燃机车和电动汽车的家庭为重点,研究内燃机车和电动汽车之间的替代模式。我们采用分数对数模型来分析影响电动汽车交通量在家庭总交通量中所占比例的因素。主要结论如下。首先,只拥有电动汽车的家庭往往比其他家庭拥有更少的家庭机动车交通量。其次,住宅区附近的充电站会延长仅有电动汽车的家庭的车辆行驶里程。第三,不同群体的就业密度对家庭 VMT 的影响不同。例如,高就业密度会缩短仅有内燃机车的家庭以及既有内燃机车又有电动汽车的家庭的 VMT。另一方面,高就业密度对仅有电动汽车的家庭的 VMT 有统计学上的积极影响。最后,在既有内燃机车又有电动车的家庭中,如果电动车更多地被用于工作出行和购物/家庭差旅,那么电动车在家庭总行驶里程中所占的比例可能会增加。

Factors influencing household VMT considering differences between ICE and electric vehicles
This study examines factors affecting household vehicle miles traveled (VMT) with a focus on the differences between electric vehicles (EVs) and conventional internal combustion engine vehicles (ICEVs). This study mainly utilizes detailed individual‐level data from the 2017 National Household Travel Survey‐California Add‐on (2017 NHTS‐CA). We first classify households into three groups such as (1) households with only ICEVs, (2) households with only EVs, and (3) households with both ICEVs and EVs. We then employ ordinary least square regression models to analyze the determinants of household VMT across three groups. Second, we focus on households with both ICEVs and EVs to look at the substitute patterns between ICEVs and EVs. We employ a fractional logit model to analyze the factors affecting the share of EVs' VMT in total household VMT. Key findings are as follows. First, households with only EVs tend to have lower household VMT than others. Second, available charging stations near residential locations lead to longer households VMT in households with only EVs. Third, employment density has different effects on household VMT by groups. For instance, high employment density leads to shorter household VMT in households with only ICEVs and with both ICEVs and EVs. On the other hand, high employment density reveals a statistically positive effect on household VMT in households with only EVs. Lastly, in households with both ICEVs and EVs, the share of EVs' VMT is likely to increase in total household VMT if EVs are used more for work trips and shopping/family errands.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
