Preemption gives life-saving seconds at each intersection

Low emergency response time is a top priority for communities, but increasing traffic is making this difficult to achieve.

Commsignia's V2X-based preemption solution is a robust and secure system that gives fire trucks and ambulances the green light and clears intersections of other vehicles before they arrive.

This preventive intervention helps avoid dangerous maneuvers and ensures that traffic is only disrupted as necessary.

V2X also acts as a safety beacon in traffic, allowing blue light vehicles to directly send alerts to all vehicles nearby.

Starter kit to provide preemption services

V2X Roadside Unit

Commsignia's RSU integrates with the Traffic Light Controller and communicates with the emergency vehicles.

V2X Onboard Unit

The OBU is installed in the emergency vehicles and integrated to the light bar, so preemption is automatically requested when necessary.

Integration services

Commsignia experts support the entire integration process.

Sensor integration

For pedestrian and cyclist safety, RSUs can be integrated with smart cameras, lidars, radars and other sensors. Emergency vehicle drivers get alerts based on sensor detections through V2X.

How Emergency Vehicle Preemption works

Emergency vehicle seeking preemption

The OBU on the ambulance sends a preemption request message to the RSU at the next intersection

Safe to enter intersection

The ambulance receives a confirmation that preemption is granted. This may include an audible or visual signal.

Intersection goes back to normal state

The ambulance sends V2X messages with its position to trigger normal state when it has left the intersection.

Clearing the next intersection before the ambulance

Smart cameras detect vehicles in the next intersection, so the RSU alerts the ambulance driver to be careful
