Passing Zone Behavior and Sight Distance on Rural Highways: Evaluation of Crash Risk and Safety under Different Geometric Conditions
To determine the effect of horizontal curvature, vertical curvature, and guardrails on driver passing behavior, a combination of field data collection and a driving simulator in a controlled environment were used. Field sites were identified along areas of concern to the Alaska Department of Transportation and Public Facilities: ...
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 ...
