Zero-Sum and Toyota InfoTechnology conducted a demonstration experiment showcasing an emergency vehicle priority system that uses an international vehicle-to-everything (V2X) standard originating from Japan based on the ultrahigh-frequency (UHF) band.

This demonstration aimed at addressing and solving one of the most important challenges faced today by emergency vehicles such as ambulances: reaching their destination in the quickest time possible, which is sometimes not feasible because of traffic congestion.

This technology prompts traffic information boards installed on the road to display information about an approaching emergency vehicle.

Upon detection of an emergency vehicle, the display boards inform motorists on the road to make way for the priority passage of the emergency vehicle, thereby enabling it to have free passage and safely reduce the travel time to its destination.
