AMBULANCE RADIO controls traffic
AMBULANCES are supposed to speed people to hospitalsâ€” but they can’t speed and they therefore can’t save some lives.
Traffic holds them back. Their average 35 mph is pretty slow.
But they may do 70 before long. A device now being patented by J. R. Schwarzkopf will put a radio transmitter in the ambulance. Traffic lights will contain tuned receivers with relays. The ambulance will streak along, its radio signallingâ€”and all the lights will turn red and all traffic pull over to clear an open speedway.
