1. A computer implemented method for controlling a plurality of vehicles passing through an intersection using a server connected to the vehicles using a network connection, the intersection comprising a crossing zone and a registration zone, the registration zone arranged outside a periphery of the crossing zone, wherein the method comprises:
receiving, at the server from each of the plurality of, a request for crossing the crossing zone of the intersection, wherein the request is transmitted from the vehicle when the vehicle enters the registration zone and the request comprises an indication of a time when the vehicle entered the registration zone,
determining, at the server, an order for the plurality of vehicles to cross the crossing zone of the intersection, wherein the determination of the order is at least based on the indication of the time when the vehicles entered the registration zone,
selecting, at the server, a first vehicle from the order of the plurality of vehicles to pass the crossing zone, and
transmitting, from the server to the first vehicle, a first instruction to pass the crossing zone of the intersection,
wherein the step of determining the order for the vehicles to cross the crossing zone of the intersection is time based using a synchronized time for the plurality of vehicles, and the registration zone functions as a buffer before the vehicles are arriving at the crossing zone and extends a predetermined distance out from the periphery of the crossing zone corresponding to a travel duration of two-five seconds for the vehicles, when travelling at an expected speed for the intersection, to reach the crossing zone from entering the registration zone.
