RSF 95, Highway Safety Improvement Program - Mobile LiDAR Data Collection and High Friction Surface Evaluation

Abstract RSF 95, Highway Safety Improvement Program--Mobile LiDAR Data Collection and High Friction Surface Evaluation During wet weather, there are two life-threatening pavement grade issues that can occur on interstates and state highways. The combination of a rainstorm leaving standing water on the roadway, one- quarter inch of pavement rutting, and a motorist traveling over 45 mph can send a vehicle into a dangerous and possibly fatal hydroplane. KTC used LiDAR (Light Detection and Ranging) to characterize and remedy dangerous road conditions on high wet-weather incident pavement sections. LiDAR will be used for water flow analysis and to topographically map the pavement surface, LiDAR is now being used to evaluate other wet weather incident areas throughout the state of Kentucky. KTC will analyze and collect data on roadways as requested for the Kentucky Transportation Cabinet and provide the subsequent corrective measures.
