Abstract

In order to design the ventilation in the road tunnel, it is necessary to know the ratio of average annual daily traffic by vehicle type. In general, the road tunnels are one- directional tunnel, so the traffic of each vehicle type does not change along the tunnel. On the other hand, in the case of network road tunnels, since the connections in the tunnels are complex, the traffic of vehicle-type varies depending on the network composition of tunnels. In the studying the easy method for calculating the ratio of vehicle type for the network road tunnel are proposed with using incidence matrix.

도로 터널 내의 환기설계를 위해서는 먼저 각 차종별 교통량 구성 비율을 알아야 한다. 일반적인 도로터널의 경우 입구와 출구의 수가 동일하고 일방향이기 때문에 유입된 차종별 구성 비율이 출구에서 나올 때까지 달라지지 않는다. 반면에 네트워크 도로터널의 경우 터널 내의 연결이 복잡한 네트워크로 되어 있기 때문에 차종별 구성 비율이 달라진다. 이에 본 연구에서는 근접행렬을 이용하여 네트워크 도로터널에서 차종별 일교통량 구성 비율을 쉽게 계산할 수 있는 방법을 제시하였다.
