Study on the Effectiveness Analysis of Policies for the Advancement of Traffic Control & Operation Systems

The national police agency has executed the project for the advancement of traffic control and operation systems in order to mitigate chronic traffic problems and to meet the global standards regarding the traffic control and operation systems. This study effort was initiated to evaluate the effects of various policies proposed for the advancement of traffic control and operation systems. The evaluation results indicated that the policies proposed for the advancement of traffic control and operation systems showed apparent and positive effects in terms of transportation mobility and safety. However, there have been many difficulties to overcome in order to settle down the policies proposed for the advancement of traffic control and operation systems as smooth as possible. For example, the violation of intersection passing method has been increased after the implementation of the advancement of traffic control and operation systems in majority of evaluation sites. In addition, lacks of awareness as well as improper operations of the advancement of traffic control and operation systems have caused drivers' confusions, which generated more traffic congestion and risks. Currently, the policies for the advancement of traffic control and operation systems focused on the improvements of traffic signal operations, including leading through movements and permissive left-turns. However, synergy effects may be expected if all of the policies including the improvements of traffic signal operations are executed together.

교통운영체계 선진화 방안 효과분석 연구

경찰청에서는 국내 교통문제를 해결하고 국제적 교통운영체계를 수립하기 위하여 "교통운영체계 선진화 방안"사업을 추진하고 있다. 본 연구는 교통운영체계 선진화 방안의 추진 효과를 분석하였으며, 그 결과 교통소통 및 교통안전측면에서 효과가 있는 것을 밝혔다. 그러나 정책에 대한 시민들의 낮은 인지도, 부적절한 현장적용 등으로 인한 교통사고의 위험 및 정체가중, 교차로 꼬리물기 위반행위 발생 등의 문제점들이 도출되었다. 현재 선진화 방안은 주로 직진우선신호, 비보호좌회전, 점멸신호 운영 등 교통신호운영 방법 개선을 위주로 추진되고 있는데, 향후 최종적으로 교통운영체계 선진화 모든 과제가 복합적으로 도입될 경우 현재 보다는 더 나은 효과를 기대할 수 있을 것이다.
