在这里，我们提出的方法，使用三维轨迹数据（一维时间×二维空间）从探测车辆获得的道路上的自然灾害造成的损坏点检测。在灾害发生后立即检测道路损坏情况，对于确保快速安全的疏散、救援和救济行动以及高效的道路维修至关重要。然而，目前只能通过闭路电视、在公路上巡逻的管理人员和公路使用者的报告来监测公路损坏情况。因此，被监测的位置的数量是有限的，并且损害检测被延迟。我们提出的方法自动估计的位置，一般道路上的广泛损害。在分析和提取灾害期间获得的探测数据的特征，我们提出的方法进行了验证，使用过去的灾害数据。我们的方法可以识别异常的车辆行为，并指出检测道路损坏的各种可能性。
Herein, we propose methods that use three-dimensional trajectory data (one-dimensional time × two-dimensional space) acquired from probe vehicles to detect damaged spots on roads caused by natural disasters. Detecting road damages immediately after a disaster is essential to ensure quick and safe evacuations, rescue and relief operations, and efficient road repairs. However, road damages are currently monitored only by closed-circuit television, administrators patrolling the roads, and reports from users of the roads. Consequently, the number of locations that are being monitored is limited, and damage detection is delayed. Our proposed methods automatically estimate the locations of widespread damages on general roads. After analyzing and extracting the features of probe data obtained during a disaster, our proposed methods were verified using the data of past disasters. Our methods can identify anomalous vehicle behaviors and indicate various possibilities for detecting road damages.
