Research Highlights

Does Compact Development Increase or Reduce Traffic Congestion?

Reid Ewing Shima Hamidi
It is now widely held, even among many state transportation departments, that you cannot “pave your way out of congestion” (at least in the long run) due to highway induced traffic and highway induced development (sprawl). Therefore, any solution to highway congestion must be multi-faceted and must, in particular, reduce the need for so much vehicular traffic. From years of other research, we know that compact development that is dense, diverse, well-designed, etc. reduces vehicle miles… Read More

Deploy Lidar Systems At Intersections To Improve Equitable Mobility

Taylor Li Stephen Mattingly
In this project, the researchers developed a series of technology transfer materials and plan to facilitate to deploy the research findings out of a NITC-funded project titled “Pedestrian Behavior Study to Advance Pedestrian Safety in Smart Transportation Systems Using Innovative LIDAR Sensors”. In that project, the researchers developed and tested a few LiDAR-based disruptive technologies to improve the safety of vulnerable road users (VRU) at intersections. The research findings were later… Read More
