# A Study on Analyzing Travel Characteristics of Micro Electric Vehicles by Using GPS Data
## 5 Conclusions  
Micro-EVs, being an eco-friendly mode of transportation and compact in size, has the advantage of being highly useful in complex urban environments. However, despite these advantages, they have not yet gained significant attention in the competition among transportation systems. Therefore, in order to promote the use of micro-EVs, it is crucial to analyze their strengths and identify the types of services where they can be effectively utilized. In response to this demand, the Ministry of Trade, Industry, and Energy conducted an R&D project that provided three types of services using micro-EVs. Micro-EVs have pros and cons; therefore, their strengths compared to conventional vehicles, along with their suitable usage types, should be assessed. As part of the R&D project, this study analyzed the strengths of micro-EVs and conducted an analysis to identify the most suitable service type for using micro-EVs. According to the analysis results of comparing micro-EVs' travel characteristics across the three service types, it can be concluded that the micro-EVs were most actively utilized for the delivery service among all service types. The comparative analysis of driving performance between micro-EVs and conventional vehicles revealed the advantages of the micro-EVs on narrow roads. Furthermore, the micro-EVs used for delivery service were more exposed to narrow roads, where they have a distinct advantage over conventional vehicles, compared to the micro-EVs used for other service types. Therefore, it is recommended that plans to promote the use of micro-EVs should be focused on delivery services, especially in old town city areas where there are many narrow roads. This study analyzes the strengths of micro-EVs compared to conventional vehicles and provides the most suitable service type where micro-EVs can be effectively utilized, contributing to the development of strategies to promote the use of micro-EVs. On the other hand, this study has the following limitations. When classifying the trips and trip chains, the location characteristics of the trip and trip chain ends were not considered. Considering the type of use of the land where trip and trip chain ends are located would enable trip and trip chains to be distinguished more accurately. In addition, no comparison was made between the travel behavior characteristics of trips and trip chains derived through GPS data and the actual use of micro-EVs. If the variable values derived from this study are corrected by comparing the actual use of micro-EVs with the characteristics of trips, more accurate results can be derived. Overall, more meaningful results can be derived if the limitations presented above are addressed. Along with this study, further research will be necessary to promote the use of micro-EVs. First, research on the specific characteristics of micro-EVs is needed. By evaluating the functionality, safety, and stability of different micro-EVs models, measures should be developed to alleviate users' concerns regarding safety. Additionally, it is important to conduct a study on the satisfaction levels of users across different micro-EVs service types and identify areas for improvement in micro-EVs.
