Internet-of-Things traffic sensor real-time messaging and stream analytics

Real-time high-resolution traffic event data streaming by edge devices turns every line-crossing event into data points that can be acted upon immediately by traffic managers, be communicated to connected vehicles, feed traffic simulation engines and digital twin systems. By streaming events for every vehicle, cyclist and pedestrian the moment they cross a georeferenced line, the proposed system (i) detects anomalies immediately after they occur, (ii) inputs to safety and efficiency applications with sub-second situational awareness information, and (iii) uses low-cost hardware and lightweight software stack for scalable network-wide deployments. This extended abstract describes the architecture of a system that we are upgrading our live fleet of traffic sensors and experiments in a simulated environment.
