Research Highlights

Pedestrian Behavior Study to Advance Pedestrian Safety in Smart Transportation Systems Using Innovative LIDAR Sensors

Taylor Li
Sirisha Kothuri , Xianfeng (Terry) Yang
Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department ... Read More

Contextual Guidance at Intersections for Protected Bicycle Lanes

Christopher Monsere
Nathan McNeil
Protected, or separated, bike lanes have become increasingly common around the United States. Studies have consistently found that people prefer bike facilities that are separated from traffic, such as off-street paths and protected bike lanes, with physical separation such as a post or curb providing increased comfort. The preference for these separated facilities appears to be greater amongst cyclists who ride primarily for recreation (as opposed to for transportation) and among those who c... Read More
