Morgan State University Researchers Use LiDAR Systems to Improve Intersection Safety and Protect Highway Work Zones
The SMARTER Center at Morgan State University is advancing transportation safety through two new research initiatives that integrate LiDAR sensing with data analytics and connected computing systems. These projects support safer intersections, smarter infrastructure, and improved protection for roadway workers across Maryland.
Improving Intersection Safety with Portable LiDAR Detection Systems
In partnership with the Baltimore City Department of Transportation, researchers are deploying Portable Detection and Communications Systems at nine intersections across three major corridors, with an additional test site on Maryland Route 195. These units combine LiDAR sensors with cameras, modems, and edge computing hardware to gather real-time data on traffic conflicts, red light violations, and pedestrian movements.
Early findings show clear benefits. On Route 195, the introduction of speed cushions reduced average speeds by 10 to 12 miles per hour, and pedestrian movements became more predictable. At the intersection of Gay and Preston Streets, more than 2,000 red light violations were recorded within ten days, and 27.5 percent of pedestrians crossed outside the designated crosswalk. The research team analyzes these data streams and provides periodic reports that help transportation officials identify high-risk patterns and prioritize safety interventions.
According to SMARTER Center Director Mansoureh Jeihani, the goal is to apply advanced sensing and predictive algorithms to detect safety hazards before they lead to collisions. The portable LiDAR units build on earlier SMARTER initiatives that integrate LiDAR, cameras, and roadside communication technologies to warn drivers and pedestrians of potential conflicts in real time. These efforts support ongoing work to advance Baltimore’s smart city infrastructure.
Real-Time Warning System to Protect Construction Workers
SMARTER researchers are also developing an intelligent work zone warning system designed to reduce crash risks for construction crews. Using LiDAR trajectory data and a time-to-collision predictive algorithm, the system evaluates approaching vehicle behavior and alerts workers when a potential collision risk is identified.
Alerts are delivered through multiple channels including audible signals, wearable haptic devices, and flashing solar-powered lights. Connected vehicles traveling through work zones can also receive visual alerts. The system is being developed and tested in collaboration with the Baltimore City Department of Transportation, the Maryland Highway Safety Office, Mead and Hunt, and P. Flanigan and Sons. A provisional patent is currently in progress.
Between 2019 and 2023, Maryland recorded approximately 7,110 work zone related crashes that resulted in more than 2,500 injuries and 45 fatalities. SMARTER’s system aims to reduce these risks through predictive analytics and real-time safety warnings.
About the SMARTER Center
The SMARTER Center is a USDOT Region 3 University Transportation Center based at Morgan State University. Established with a 15 million dollar grant from the U.S. Department of Transportation in 2023, it is the first regional UTC led by an HBCU. The Center supports research, education, and technology transfer efforts that enhance mobility and safety throughout the Mid Atlantic region.
