Enhancing Road Safety with Smart Intersections
The Smart Intersections Warning System is designed to prevent collisions between vehicles and vulnerable road users (VRUs) at intersections. By combining roadside cameras, cloud-based detection algorithms, and real-time communication, the system predicts potential conflicts and alerts drivers before they happen. Sensor data is processed and transmitted to connected vehicles, enabling them to respond to potential threats—whether driven manually or autonomously. As a key component of Cooperative Driving Automation, this technology bridges infrastructure and vehicles to create safer, smarter intersections. Learn more at smartintersections.org.

00:00:01 in this video we will demonstrate the smart intersections project warning system the warning system is designed to alert drivers of potential collisions with vulnerable Road users or vrus at intersections by leveraging roadside information in this demonstration two roadside cameras are installed at the Northeast and southwest corners an image detection algorithm is implemented at
00:00:25 the cloud and detects Road users in real time the detection results are encoded into to sensor data sharing messages or sdsm messages and broadcasted by the roadside unit the onboard unit implemented on the ego vehicle can receive the message and send it to the onboard computer the ego vehicle makes a left turn at the intersection meanwhile a VRU
00:00:47 is crossing the street at the beginning both the vehicle and the VRU are far from the intersection so a warning message is not issued as the vehicle in Bru approach the intersection the algorithm will will predict their future trajectory and check the potential Collision once there is a potential Collision a warning signal is issued and a red icon flashes
00:01:09 on the right of the web application when the VRU passes the street no Collision will occur and there is no warning to learn more about the smart intersections project and its other products including the infrastructure-based perception system for Cooperative driving automation called msite please visit our website at smart intersections dog work
