PURPOSES : Many people recommend the expansion of the drone market and various ways of using drones. However, unreasonable expansion may cause various social problems. Therefore, criteria and systems for the expansion are required. This paper presents a review of the system using drones for managing and enforcing illegal parking, and recommendations on improvement. METHODS : This paper presents a review of the system using drones for managing and enforcing illegal parking, and recommendations on improvement. RESULTS : This study shows that new enforcement criteria are required for a new enforcement method using drones. In addition, consignment operation is needed to solve workforce shortage and secure expertise, and flight mitigation criteria are required, considering the illegal parking characteristics based on region and time. Finally, CCTV operation guidelines should be improved to clarify the definition of drone images and prevent unreasonable information collection. CONCLUSIONS : Illegal parking enforcement using drones is an efficient method that is highly feasible and solves enforcement limitation issues, such as the lack of workforce and equipment. A prior institutional review is required to apply new technologies more efficiently, and proposals on improving the legal systems with limitations are required through continuous research.

PURPOSES : In this study, the causality between smart parking user services and its satisfaction level was analyzed statistically, and a smart parking priority decision model was established in terms of the user side. METHODS :The results of the Daegu Metropolitan City survey for the parking state, parking fee, transfer, convenience of use, facilities, and safety that could influence smart parking user satisfaction were used. A structural equation model in SPSS 26 and AMOS 26 programs that facilitates hypothesis testing and importance factor analysis between observed and latent variables was used. RESULTS : The results demonstrated that the importance factor loading on smart parking user services was in the following order: convenience of use (0.996), parking facilities (0.814), safety (0.803), parking information (0.706), transfer (0.618), and parking fee (0.426). Among them, the parking fee was not quite influential in decision making. CONCLUSIONS : The most influential user service on smart parking information systems was the convenience of use, in which congestion in parking lots and parking time were the most influential variables. The most influential variables were in the following order: in parking facilities, the route design of vehicle flow and size of the parking garage; in safety, the entrance location and the level of wear; in the parking state, the availability of parking space and parking fees; and finally in transfer, the convenience of transfer to other modes and the number of transfer parking lots.
