Abstract

A method and a traffic control entity (100) for controlling a group of vehicles (104) capable of autonomous driving without requiring a driver, to allow an emergency vehicle (102) to pass the group of vehicles (104) which are travelling concurrently in multiple lanes on a road. When detecting that the emergency vehicle (102) is approaching the group of vehicles (104) e.g. from behind, the vehicles in the group (104) are identified based on information (108) about current position and movement of the vehicles (104). The traffic control entity (100) then issues a command (106) instructing the identified vehicles to adjust their lateral positions relative the lanes to create a passage along the group of vehicles (104). Thereby, the emergency vehicle (102) is able to move through the passage without having to slow down significantly.
