3D Virtual Sight Distance Analysis Using Lidar Data
This research project investigated advanced safety analysis methodologies for drivers’ sight distance based on high resolution data acquired using lidar (light detection and ranging) technology. Sight distance analyses require careful and detailed field measurements to facilitate proper engineering decision making regarding ...
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 ...
A Platform for Proactive Risk-Based Slope Asset Management - Phase II
The lidar visualization technique developed by this project enables highway managers to understand changes in slope characteristics along highways. This change detection and analysis can be the basis of informed decisions for slope inspection and remediation. Mitigating unstable slopes and their associated hazards reduce ...
