Research Highlights
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…

Developing SafeSpot: A New Crowdsourcing Tool for Real-Time Near-Miss Detection and Risk Mapping
Tanmoy Bhowmik Primal Pappachan
Transportation safety analysis has traditionally relied on police-reported crashes to identify dangerous locations. This reactive approach overlooks the many near-miss incidents and perceived hazards that occur daily but go unrecorded. Understanding such incidents is essential for proactive transportation safety planning, allowing for interventions before injuries or fatalities occur. However, current practice lacks a systematic way to collect and analyze near-miss data, creating a critical gap…
