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

An Update of E-Bike Purchase Incentive Programs in North America

John MacArthur
The electric bicycle (e-bike) is a low-emission mode of transportation that offers communities benefits in the areas of health, planning, time, cost, street safety, congestion, air pollution, noise pollution, and energy security (BenoƮt et al., 2011). E-bikes enable more people to ride a bicycle for longer distances despite physical limitations, difficult terrain, and the presence of cargo (MacArthur et al., 2018). In the most recent U.S. National Household Travel Survey (NHTS), completed in ... Read More
