Assessing the Risk of Landslide in Oklahoma Highways Using LiDAR

Landslides are a threat to public traffic when they occur on roads that pass through mountainous regions. When both external and internal conditions of the fill or cut slopes change to an extent that the slopes lose their stability, a landslide happens. The current approach to dealing with landslide by Oklahoma Department of Transportation (ODOT) is primarily reactive because there is no effective monitoring mechanism to properly assess the risk of landslide. When the damage is already done, expensive repair follows because the repair process is time driven and the use of resources may not be the most cost-effective. Traffic lane closure during the repair affects public road users’ travel time and increases road users’ costs. Therefore, a more proactive approach to landslide prevention as well as emergency response is needed. The proposed research will investigate the use of Light Detection and Ranging (LiDAR) technology for slope monitoring and landslide/rockslide risk assessment on major highways in Oklahoma. A rockslide recently occurred in Oklahoma’s Arbuckle Mountains on Interstate 35 (I-35) due to excessive rain in June 2015. This resulted in a few weeks of lane closure and approximately one million dollars for repair. This research will yield an innovative procedure for agencies to use to monitor the slopes and assess the risk of landslide on highways in mountainous regions. Proactive actions can be taken to reduce the disruptions and dangers to the public traffic due to the disaster of landslide.
