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 ...
Rendering of Dense, Point Cloud Data in a High Fidelity Driving Simulator
Driving Simulators are advanced tools that can address many research questions in transportation. Recently they have been used to advance the practice of transportation engineering, specifically signs, signals, pavement markings, and most powerfully to examine the safety and efficiency of alternative transportation solutions. ...
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 ...
Transportation Corridor Resiliency in the Face of a Changing Climate
The effects of a changing climate on transportation corridor slopes are poorly understood, but several recent studies have suggested that landslide activity, especially rockfall, is likely to increase as a consequence of the increased occurrence of intense precipitation events. Effects from climate change such as extreme ...
