Unmanned Aircraft System Assessment of Landslide Safety for Transportation Corridors
An assessment of unmanned aircraft systems (UAS) concluded that current, off-the-shelf UAS aircraft and cameras can be effective for creating the digital surface models used to evaluate rock-slope stability and landslide risk along transportation corridors. The imagery collected with UAS can be processed using a photogrammetry ...
Modeling Passing Behavior on Two-Lane Rural Highways: Evaluating Crash Risk Under Different Geometric Configurations
Passing maneuvers on rural two-lane highways are a complex task with a significant effect on safety, capacity, and service quality. This maneuver, which involves driving in the lane of the opposing traffic, is associated with simultaneously increasing crash risk and increasing the driver's speed. Understanding drivers' passing ...
