Development of Traffic Obstacles Detection System on Urban Tunnels with Heavy Traffic Flow

It will be further important to take safety measures to prevent accidents in tunnels that may result in tremendous social loss. This paper introduces algorithms to detect traffic obstacles, which automatically and precisely detects an unusual traffic flow at tunnels with heavy traffic flow. The algorithms for automatic detection of an unusual traffic flow detect unusual incidents of traffic flows (e.g., standing or escaping vehicles) based on processing of image data collected from multiple CCTV cameras installed in tunnels. The algorithms however were considered to have some problems in detecting a traffic obstacles in urban tunnels with heavy traffic flow, which are even ordinary vehicles standing at the end of a queue due to traffic jam may be detected as abnormal traffic flow, and the cameras installed at an insufficient height because of tunnel structure may cause invisible vehicles and/or fields of which image data would not be processed.
