A computer program that reserves slots at an intersection might be a way to ease gridlock and boost safety.
Future cars could be equipped with computer systems that "call ahead" to intersections.
The intersections can then reserve a green light for the approaching vehicle.
The concept could avoid gridlock and reduce collisions, claims a computer scientist.
Computers can reserve your plane ticket, your hotel room and your restaurant table. Why not your place at an intersection?
The concept is simple: a computer in a car calls ahead to the nearest intersection it is headed towards, and says it will arrive at a given time. The intersection checks to see if anyone else is arriving then, and if the slot is open, it tells the car to proceed. If it isn't, it tells the car that and the car is responsible for slowing down or stopping.
