Preemption reduces response times for emergency vehicles
Solutions
Visibility matters
Priority and Preemption with Safety
Intersections are the most dangerous points of an emergency call. Modern vehicle sound insulation frequently blocks out sirens, leaving motorists unaware until it's too late, endangering crews, civilians, and expensive assets.
The Emergency Safety Suite solves this by fusing secure V2X (vehicle-to-everything) communication with cloud-aware network intelligence via V2N.
Powered by the Commsignia Trust Engine digital twin platform, the system delivers real-time, verified traffic data. It sees around corners to detect red light runners, track queue build-ups, crashes and lane closures that legacy sensors and priority solutions miss completely.
Corridor-Wide Priority
Grants coordinated signal priority across entire transit corridors rather than isolated, single-intersection control.
Stress-Free Cabin Experience
Provides intuitive, non-distractive feedback to eliminate the high-stress "dilemma zone" for emergency drivers.
Ecosystem Interventions
Broadcasts digital alerts directly to surrounding connected civilian dashboards, prompting drivers to clear lanes early.
Predictive Hazard Alerts
Warns crews of hidden cross-traffic risks, red-light violators, and jaywalkers well before they are visible.
Zero-Maintenance Operations
Enables remote management, cloud debugging, and system optimization without physical service calls.
Actionable ROI Dashboards
Quantifies system health, response times, and near-miss metrics for clear performance tracking.
10-15% Faster Response
Coordinated corridor preemption slashes response delays compared to legacy systems.
Financial & Legal Protection
Guards municipalities against the cascading legal liabilities and compounding financial fallout of intersection crashes.
Fleet Reliability
Protects vehicles and personnal to mitigate the 20,000+ emergency collisions that occur annualy in the U.S.
Seamless Integration
Built on rigorous automotive standards, integrating smoothly into existing workflow without expensive rip-and-replace cycles.
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
Traffic Light Controller handshakes with RSU
The RSU negotiates with the Traffic Light Controller to run the implemented preemption logic
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
