Abstract

This paper investigates the travel and charging choices of electric car users who also own a conventional-fuel vehicle. While travel behavior impacts on charging decisions have been explored in earlier studies, studies have excluded the possibility of shifting to conventional fuel vehicles by electric car users. In addition, the effects of the time spent at destinations on charging choices are also unexplored in travel behavior literature. Using a stated choice data collected in New Delhi, India, the study estimates a nested integrated choice and latent variable model to assess individuals’ choices among ‘travel according to the tour plan without charging the EV, ‘travel according to the tour plan with charging the EV’ and ‘complete the tour by shifting to conventional-fuel vehicles’. The study finds that increased tour distance leads to the choice of conventional fuel vehicle over the electric car. Besides, participation in a work tour and trip chain complexity positively affects choice of conventional fuel vehicles. While a higher initial SoC leads to decreased preferences for completing a tour on electric car with charging and shifting to conventional fuel vehicles. Overall, the study finds that travel behavior influences charging choices and travel decisions, E-car users still value conventional-fuel vehicles in accomplishing their travel patterns if E-car attributes are unfavorable.

考虑到汽车属性和出行链复杂性，评估电动汽车用户充电和出行决策的陈述选择研究——Case新德里，印度

本文研究了拥有传统燃料汽车的电动汽车用户的出行和充电选择。虽然在早期的研究中已经探讨了出行行为对充电决策的影响，但研究排除了电动汽车用户转向传统燃油汽车的可能性。此外，在目的地停留的时间对充电选择的影响在旅行行为文献中也未被探讨。利用在印度新德里收集的声明选择数据，该研究估计了一个嵌套的综合选择和潜在变量模型，以评估个人在“按照旅游计划旅行但不给电动汽车充电”、“按照旅游计划旅行但给电动汽车充电”和“换用传统燃料汽车完成旅行”之间的选择。研究发现，行驶距离的增加导致人们选择传统燃油汽车而不是电动汽车。此外，参与工作旅行和行程链复杂性正影响传统燃油汽车的选择。而较高的初始SoC则会降低人们对电动汽车的偏好，因为他们不愿意在完成一次旅行后再充电，转而使用传统燃油汽车。总体而言，研究发现出行行为影响充电选择和出行决策，在电动汽车属性不利的情况下，电动汽车用户仍然选择传统燃料汽车来完成他们的出行模式。

期刊介绍： Transportation Research: Part A contains papers of general interest in all passenger and freight transportation modes: policy analysis, formulation and evaluation; planning; interaction with the political, socioeconomic and physical environment; design, management and evaluation of transportation systems. Topics are approached from any discipline or perspective: economics, engineering, sociology, psychology, etc. Case studies, survey and expository papers are included, as are articles which contribute to unification of the field, or to an understanding of the comparative aspects of different systems. Papers which assess the scope for technological innovation within a social or political framework are also published. The journal is international, and places equal emphasis on the problems of industrialized and non-industrialized regions. Part A''s aims and scope are complementary to Transportation Research Part B: Methodological, Part C: Emerging Technologies and Part D: Transport and Environment. Part E: Logistics and Transportation Review. Part F: Traffic Psychology and Behaviour. The complete set forms the most cohesive and comprehensive reference of current research in transportation science.
