국내에는 버스전용차로를 운영하고 있으나 버스우선신호 제어는 현장적용에 따른 효과평가 사례가 없이 시뮬레이션 기법에 의존하여 효과를 예측하고 있다. 본 연구는 향후 국내 도입이 예상되는 버스우선신호 제어의 운영 효과를 현장자료를 수집하여 평가하였다. 하남시 버스운행구간 중 3개 교차로를 선정하여 첨두와 비첨두 시간으로 구분하여 사전,사후 조사를 실시하였고 현장평가를 위한 효과척도는 통과 교통량과 통행속도로 선정하였다. 통과 교통량의 경우, 승용차는 주도로 통과 교통량이 7.4% 감소된 것으로 파악되었으나, 버스는 통과 교통량이 12.8% 증가된 것으로 분석되었다. 통행속도의 경우, 시간대별 주도로 방향의 차종별 통행속도와 시간대별 통행시간 분포를 분석한 결과, 버스우선신호를 적용하여 버스의 통행속도 및 통행시간이 크게 향상되고, 통행속도의 분포도 개선되는 것으로 나타났다. 버스우선신호 제어기법의 적용을 통하여 승용차와 버스 모두 통행속도 증가효과가 있는 것으로 분석되었다.
Alternative Abstract
Currently many urban cities in Korea implemented exclusive bus lanes operation, but none of the cities introduced the bus signal priority system as a functional element of the signal control systems. Thus, there was no field test result reported on the performance change from the introduction of the bus signal priority system. This study intended to evaluate performance of the bus signal priority system based on field test. Three signalized intersections in Hanam City was selected as a test site which installed a DSRC-based bus signal priority system. Before and after study was performed with consideration of two control variables such as peak vs. off-peak, passenger car vs. bus, using two measure of effectiveness(MOE), speed and volume. In terms of traffic volume, passenger car in a major direction reduced by 7.4% but bus increased by 12.8% after introducing the bus signal priority system. There was no significant volume change in both passenger car and bus for the cross street. In terms of average speed, passenger car in a major direction increased by 6.5% and bus increased by 10.5% after introducing the bus signal priority system. Statistical tests showed that those speed differences were statistically significant at the 95% of confidence level. In addition, the quality of distribution of travel times was also improved. Therefore, the average speed and quality of flow of bus could be greatly improved by introducing the DSRC-based bus signal priority system.
