Abstract

Short and medium distance traffic is considered as a major cause of urban traffic problems such as traffic congestion and greenhouse gas emissions. Many advanced transportation countries are making efforts to tackle these problems by introducing micro-mobility modes represented as electric scooters and electric bicycles. Since they are mainly operated in a dockless fashion and can provide First-Mile Mobility (FMM) and Last-Mile Mobility (LMM) services, they can not only replace short and medium distance traffic but also promote public transportation service. This study developed an algorithm to calculate the slope-dependent travel time of micro-mobility modes and demonstrated it in four districts (i.e., Busanjin-gu, Seo-gu, Dong-gu, and Jung-gu) with high public transport operation density in Busan Metropolitan City. As a result, the travel time derived through the developed algorithm yielded a more realistic result than the travel time at the maximum speed (i.e., 25kph) with no consideration of slope. Consequently, when the micro-mobility service is provided through a sufficient understanding of the underlying factors affecting it like this study, its positive effect can be expected.

중단거리 통행은 교통혼잡과 온실가스 배출과 같은 도시교통문제의 주요 원인으로 간주된다. 다수의 교통선진국들은 전동킥보드와 전기자전거로 대변되는 마이크로 모빌리티 수단들을 도입하여 도시교통문제 해결을 위하여 노력하고 있다. 이러한 수단들은 주로 비거치식(Dockless)으로 운영되어 중단거리 통행을 대체할 수 있을 뿐만 아니라 출발접근(First-Mile Mobility, FMM) 및 도착접근(Last-Mile Mobility, LMM)서비스를 제공하여 대중교통 이용을 활성화시킬 수 있는 장점이 있다. 본 연구는 경사를 고려한 마이크로 모빌리티 수단의 통행시간 산정 알고리즘을 개발하고 부산광역시에서 대중교통 운행밀도가 높은 네 개 구(부산진구, 서구, 동구, 중구)를 대상으로 실증하였다. 분석 결과, 본 연구에서 개발한 알고리즘을 통해 도출된 경로통행시간은 경사의 고려여부에 관계없이 최대속도(25kph)로 주행하는 통행시간보다 좀 더 현실적인 결과를 제시하였다. 따라서 본 연구와 같이 마이크로 모빌리티 수단의 이용에 영향을 미치는 요소들에 대한 충분한 이해를 통해서 서비스를 제공해야지만 그 효과를 기대할 수 있을 것이다.
