버스베이 설치에 따른 통행시간비용 절감효과 분석: 왕복 4차로 도로를 중심으로

초록

Recently, as the problem of subway congestion has intensified due to COVID-19, the need to ease the concentration of public transit share of subway through bus improvement has increased. Bus bay is a facility that is encouraged to be installed as part of transportation policy for public transportation, but in Korea, bus bay has several problems and is recognized as an example of transportation policy that prioritizes vehicle traffic, so it is time to discuss its necessity. Therefore, this study derived the quantitative effects of bus bay installation according to stop time and congestion, such as traffic change and travel time reduction benefits, and investigated conditions requiring bus bays through micro-simulations on two-way 4-lane road. As a result of the analysis, the traffic efficiency of general vehicles improved when the bus bay was installed, while the traffic efficiency of buses decreased, and this effect was greater when the congestion is high. The installation of the bus bay caused the benefit of travel time savings when the bus stop time was long due to crowded traffic conditions, but in most other cases, the negative benefit of travel time savings was caused. Considering that bus bays hinder the traffic flow of buses and cause negative benefit of travel time savings, it seems that bus bays should be avoided except for special conditions when installing bus stops.
