Abstract
When we analyze vehicle choice behavior, including electric vehicles (EV), it is important to disclose the relationship between these choices and EV charging stations.
Thus, in this study, we analyzed the relationship between vehicle choice behavior and its factors, which are costs, class, and the type of vehicle, using conjoint analysis in four case studies divided by the development of EV charging stations and buying purpose.
The results of the analysis which income level is not considered are below. In the case wherein there were insufficient EV charging stations and the buying purpose was for a long trip, the utility scores imply a negative decision for EVs. Even in the case wherein the purpose was a short trip, the EV's value was still negative. On the other hand, in the case wherein there were sufficient EV charging stations constructed and the purpose was a long trip, the scores indicate a positive tendency toward EV-buying. The scores for costs are negative in all cases. The results of the analysis of each income level are below. In the case wherein there were insufficient EV charging stations, the importance score of vehicle type is the highest at high income level. In the case wherein there were sufficient EV charging stations, the importance score of type is the highest at low income level. Low income person places importance on costs than high income person.
