Abstract

Standards suitable for local conditions on deciding one-way road are desperately required to solve traffic congestions at the backside roads in the old downtown areas which were not designated as a road by urban planning. Therefore, this study intends to re-establish a standard to decide one-way road which is regarded to be of the greatest effect among traffic system control methods in order to control one-way road system more efficiently. Also, this paper suggests a standard for such decision to improve efficiency of using backside roads and expand designation of one-way road. AHP (analytic hierarchy process) was carried out among the traffic experts to find out the factors to decide one-way road system. Its result reveals that importance of causing accident to walking quantity and traffic was high. 10,000 cases out of all the possible scenarios of accident by combining detailed evaluation items and scales were extracted to draw the outcomes of analyzing the scenarios, which were schematized in a graph. As a result, division by three sections of point of inflection was verified into $1{\leq}$ section A<1.91, 1.9$1{\leq}$ section B<2.08, and $2.08{\leq}$ section C<3. In other words, priority of deciding one-way road should be given to section C, the highest total point, while posterior to section A, where relatively low points are distributed. The standard on deciding one-way road suggested in this paper may be used for designating one-way road and basic data to re-establish the relevant system in the future.

도시계획상 도로로 지정되지 못한 구도심의 이면도로에 있어서 교통혼잡 해소 등의 교통문제 해결을 위해서는 국내에 맞는 일방통행 선정기준의 정립이 절실히 필요하다. 이에 본 연구에서는 일방통행제의 효율적인 운영을 위해 교통체계관리기법 중 가장 효과가 큰 일방통행의 선정기준을 재정립하고, 이면도로를 대상으로 이용효율 및 일방통행 지정 확대를 위한 선정기준을 제시하고자 한다. 일방통행제 선정요인을 도출하기 위해 교통관련 전문가 집단을 대상으로 계층분석법(AHP)을 수행한 결과, 보행량 및 보행교통 사고요인의 중요도가 높게 분석되었다. 세부 평가항목과 평가척도를 조합한 발생가능한 모든 시나리오 중 10,000개를 임의 추출하여 시나리오별 분석 결과를 그래프화 한 결과, 변곡점을 갖는 3개 구간($1{\leq}$A구간<1.91, 1.9$1{\leq}B$구간 <2.08, $2.08{\leq}C$구간<3)으로 분석되었다. 본 연구 수행을 통해 제시된 이면도로 일방통행 선정기준은 향후 일방통행 지정 및 재정비 시 기초자료로 활용될 수 있을 것으로 판단된다.
