### Travel Behaviors of Micro-EVs by Service Type  
The travel behavior characteristics of the micro-EVs used for each service type are shown in Table 7. Furthermore, Figure 4 shows the graph comparing the travel behavior characteristics of micro-EVs by service type. The detailed results of the analysis of travel characteristics by service type for micro-EVs are as follows. \begin{table}

Table 7: Travel behavior characteristics of micro-EVs used for each service type. The shared transport service users used micro-EVs for an average of 0.7 h and drove an average of 15.6 km daily. Moreover, the average number of daily trips and trip chains were 4.1 and 1.1. In addition, the travel distances per trip and trip chain were 3.5 km and 14.0 km, respectively. The average speed per trip was 20.2 km/h, and there were 3.6 trips per trip chain. The micro-EVs used for the shared transport service were found to be more actively used on weekends than on weekdays because all variables related to trip, trip chain, and daily use were more significant on weekends than on weekdays. The micro-EVs used for the shared transport service had fewer trips and trip chains, which means that the micro-EVs were used less than the micro-EVs for other service types. However, the micro-EVs for the shared transport service had the highest average travel distance per trip compared to other service types. Moreover, the daily travel distance of the shared transport service's micro-EVs was longer than those used for the public service.
