ALERT: Adaptive Lane Emergency Routing andTraffic Signal Optimization – A Pilot Implementationof a Smart Green Corridor System in SignalizedUrban Intersections
Year: 2026
Type: preprint
Abstract: Urban road congestion presents great limitations to the time release of emergency services, usually resulting in delays for moreserious medical emergencies. This research proposes an integrated automated Green Corridor system based on geotagging,GPS, and embedded camera-based acknowledgment systems for prioritizing emergency vehicles. Here, Geotags placed 200meters upstream of intersections enable preemptive signal-timing adjustments, while dual confirmation through the camerashelps to detect ambulances accurately even in adverse weather conditions or heavily congested traffic. The proposed systemeliminates human intervention and helps all classes of ambulances without any hardware installations. Real-time alerts, suchas patient identification and ETA levels, help hospital preparedness and traffic management coordination. The simulation onSUMO shows a great 65% reduction in response time and better flow dynamics on multijunction roads, for traffic aggregateswithin networks, and route detours. The scalable, technology-driven solution solves unaddressed issues of emergency trafficmanagement while securing better system reliability and preparedness.
