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 ...
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. ...
Alternative Information Signs: an Evaluation of Driver Comprehension and Visual Attention
The effectiveness of a traffic sign is collectively influenced by the sign’s understandability, legibility distance, glance legibility, and learnability; however, understandability has been repeatedly identified as a one of the most important measures of effectiveness. This study contributes to best practices for evaluating ...
