### Travel Behaviors of Micro-EVs by Service Type
Also, the micro-EVs for the shared transport service visited more places than the micro-EVs for the public service, as the shared transport service micro-EVs' number of trips per trip chain was more significant than the public service micro-EVs' number of trips per trip chain. The delivery service users used micro-EVs for 3.5 h a day and traveled 38.5 km on average daily. Furthermore, the daily number of trips and trip chains were 24.1 and 2.6, respectively. The travel distances per trip and trip chain were 1.8 km and 17.7 km, respectively. The average travel speed per trip was 20.7 km/h, and the number of trips per trip chain was 9.4. Micro-EVs used as part of the delivery service were also more actively used on weekends than weekdays. Excluding the average travel distance per trip, other index values were higher on weekends than during the weekdays. For the micro-EVs used as part of the delivery service, all other indicators were higher than other service types, except for the average travel distance per trip. Even if the average distance per trip was lower than that of other service types, the average daily usage time was higher, because the number of trips was about six times that of other service types' micro-EVs. Therefore, the values of trip and trip chain indicators were higher than those of other service types. The public service users used micro-EVs for an average of 0.8 h per day and traveled an average of 11.0 km, with an average of 4.2 daily trips and 1.9 daily trip chains. In addition, the travel distances per trip and trip chain were 2.4 km and 5.4 km, respectively. Also, the speed was an average of 15.2 km/h per trip, and the number of trips per trip chain was 2.3 times. The micro-EVs used as part of the public service had a longer travel distance per trip on weekdays than on weekends, which was judged to be a result of the

The micro-EVs used as part of the public service had lower average travel speed and daily travel distance values than those of the other service types. The number of trips was larger than for the micro-EVs used as part of the shared transport service, but the number of trips per trip chain was smaller, meaning that the micro-EVs used for the public service visited fewer places than the micro-EVs used for the shared transport service. The comparison of travel behavior characteristics across different micro-EV service types revealed that the micro-EVs used for the delivery service were the most actively utilized. Deliveries involve visiting multiple locations, resulting in a high frequency of trips, but each trip for a single purpose tended to be short in length. Additionally, due to the high frequency of trips, the number of trip chains planned for multiple purposes was relatively high for the micro-EVs used for the delivery service. In contrast, micro-EVs used for the shared transport service were primarily used as a means of connecting to public transportation, which resulted in longer trip distances per trip. However, because of this, it was more difficult to group the trips into chains, leading to fewer trips per chain compared to other service types.
