Kerala’s Green Corridors & Traffic Priority Systems: Saving Lives on the Road

SpotGenie Gyaan uncovers how Kerala’s emergency corridors and signal-based priority systems enable faster ambulance transit-reducing response times and improving outcomes.

What Is a Green Corridor?

Kerala’s traffic police create dedicated, cleared routes to allow unrestricted ambulance travel during organ transfers and patient emergencies. Vehicles and manual traffic management clear the path ahead. Examples include:

A 400 km journey from Mangaluru to Kochi for a 15-day-old infant-completed in 5.5 hours with full public cooperation.
A 200 km transplant route from Kozhikode to Kochi-completed in just 2.5 hours during a hartal day.

Next-Gen Priority: EVPS on NH-66, Trivandrum

The Emergency Vehicle Priority System (EVPS) includes real-time traffic signals toggled green when ambulances approach intersections. Recently deployed on the Thiruvananthapuram–Kazhakkoottam stretch, it cut travel times from 54 to 40 seconds per 2 km, saving ~10 seconds per signal.

What Ahmedabad Shows-V2X Trials for Emergency & Bus Priority

Ahmedabad tested Vehicle-to-Everything (V2X) technology-where ambulances or BRTS buses communicate with traffic signals. Results: 35% reduction in travel time and up to 80% less waiting at signals. The system uses sub-GHz communication to enable real-time signal control.

Why These Systems Matter

🚑 Ambulance travel time reduced by 20–30%
🫀 Improved organ transport reliability and increased transplant success
🚨 Faster emergency response and better odds during critical situations

Challenges & Replication Hurdles

Manual clearance during green corridors can disrupt general traffic flow
EVPS & V2X require infrastructure upgrades, vehicle-based transmitters, and coordination across departments
Awareness among drivers and citizens is essential for effective corridor compliance

Conclusion

Kerala’s blend of manual green corridors and modern EVPS trials is transforming emergency mobility. Combining human coordination with traffic sensor tech saves precious minutes that mean lives.
