초록

2차로 양방향 도로(이하 2차로 도로)의 주요한 특징은 화물차량 등의 저속차량으로 인하여 발생하는 차량군과 차량추월 행태이다. 차량추종과 차량추월모형이 결합된 2차로 도로 교통류 모형을 개발하기 위해서는 2차로 도로에 적합한 차량추종모형의 개발이 필수적이다. 2차로 도로에서 고속차량은 저속차량의 후미에서 차량추종을 수행함과 더불어 추월을 수행하게 되며, 이 과정에서 짧은 차간거리가 발생하게 된다. 또한 저속차량을 추종하는 차량은 대항교통류의 차두시간분포 내에서 적정 공간을 이용하여 차량추월을 결정하게 된다. 따라서 2차로 차량추종모형은 짧은 차간거리에서 차량주행과 더불어 차두시간분포를 설명해야 한다. 추가적으로 국내의 2차로 도로규모를 고려하면 대규모 도로망을 모의실험할 수 있는 모형이 필요한 실정이다. 국내의 경우, 2차로 차량추종모형에 대한 연구는 거의 보고되고 있지 않다. 본 연구에서는 대규모 가로망에 적용이 가능하면서 2차로 도로의 차량추종행태를 보다 현실적으로 구현할 수 있는 모형을 개발하였다. 개발된 모형의 실험적 평가 결과, 혼잡 교통류의 특성 중 하나인 가다서다(stop-and-go) 현상과 차두시간분포를 효과적으로 설명하는 것으로 나타났다. 따라서 본 연구에서 제시된 차량추종모형이 차량추월모형과 결합된 경우, 보다 현실적으로 2차로 도로 교통류를 설명할 수 있을 것으로 판단된다.

The key characteristics of two-lane-and-two-way traffic flow are platoon and overtaking caused by low-speed vehicle such as truck. In order to develop two-way traffic flow model comprised of CF(car-following) and overtaking model, it is essential to develop a car-following model which is suitable to two-way traffic flow. Short distance between vehicles is caused when a high-speed vehicle tailgates and overtakes foregoing low-speed vehicle on two-way road system. And a vehicle following low-speed vehicle decides to overtake the front low-speed vehicle using suitable space within the headway distribution of opposite traffic flow. For this reason, a two-way CF model should describes not only running within short gap but also headway distribution. Additionally considering domestic two-way-road size, there is a on-going need for large-network simulation, but there are few studies for two-way CF model. In this paper, a two-way CA model is developed, which explains two-way CF behavior more realistic and can be applied for large road network. The experimental results show that the developed model mimics stop-and-go phenomenon, one of features of congested traffic flow, and efficiently generates the distribution of headway. When the CF model is integrated with overtaking model, it is, therefore, expected that two-way traffic flow can be explained more realistically than before.
