본 논문에서는 고속도로 반복정체구간의 소통개선을 위하여 사용되고 있는 갓길차로를 버스전용차로로 운영하는 갓길버스전용차로제 운영 방안을 제시하고 시뮬레이션을 수행하여 기존 갓길차로제 및 중앙버스전용차로&갓길차로제와 비교 평가 하였다. 평가결과에 의하면 현재와 같이 모든 차량을 위한 갓길차로를 운영하는 것보다 소통 및 안전측면에서 유리한 것으로 평가 되었다. 그리고 중앙버스전용차로&갓길차로 보다는 통과버스의 통행속도는 다소 감소하지만 진출입 버스의 통행속도는 증가되고 승용차의 통행속도가 크게 향상되었으며, 승용차와 버스 통행속도를 산술평균한 전체 차량의 통행속도도 크게 증가하는 것으로 분석되어 수송인원 효율성도 향상되는 것으로 분석되었다. 특히 승용차와 버스의 통행속도 차이가 크게 줄어 들어 교통흐름이 안정화되고 승용차들의 버스전용차로 위반 행위를 크게 줄일 수 있을 것으로 판단된다. 그리고 갓길차로 운영시간도 크게 감소되어 갓길차로 본래 기능을 최대한 유지시킬 수 있다. 이러한 영향으로 갓길버스전용차로제가 중앙버스전용차로&갓길차로제보다 사고위험도가 크게 감소되고 사고심각도가 큰 교차상충은 발생되지 않는 것으로 분석되었다.

In this paper, the dynamic hard shoulder running for bus only (HSRFBO) was presented to solve the traffic congestion by increase the capacity in chronic congested sections of highways, and a simulation was performed to evaluate the comparison with the current hard shoulder running for all vehicles(HSRFAV) and median bus only lane and HSR(MBOLHSR). According to the evaluation results, it was evaluated to be more advantageous in terms of traffic flow and safety than the current HSRFAV. In addition, the speed of passing buses is slightly reduced compared to the MBOHSR, but the speed of entering and exiting buses is increased and the speed of buses and cars is greatly improved. Therefore It was analyzed that the efficiency of transport personnel was also improved. In particular, it is expected that traffic flow will be stabilized as the difference in speed between passenger cars and buses will be greatly reduced, and violations of exclusive bus lanes by passenger cars will be greatly reduced. In addition, the operation time of HSR is greatly reduced, so that the original function of the shoulder lane can be maintained as much as possible. As a result, it was analyzed that the risk of accidents was significantly reduced when operating HSRFBO compared to when operating MBOHSR, and cross-conflicts with high accident severity did not occur.
