1. A method for controlling a flow of traffic on a roundabout, wherein the flow of traffic is controlled by a traffic control unit, with which road users, which have entered the roundabout and/or approach the roundabout to enter the roundabout, are networked in a network and communicate via messages, and wherein for entering, each road user of the road users transmits a request to the traffic control unit, the method comprising:
before entry of each road user, determining, by the traffic control unit, the flow of traffic on the roundabout based on previous messages received via a radio-based communication network from each user and sensor data received via the radio-based communication network from at least one of a camera, a radar sensor, a Light Detection and Ranging (LIDAR) sensor, or an infrared sensor on the roundabout;
ascertaining, by the traffic control unit, real-time parameters including an instantaneous speed and current positioning of each road user based on the previous messages;
calculating, by the traffic control unit, a travel time required to exit the roundabout for each road user in real time using the real-time parameters;
generating, by the traffic control unit, based on the travel time required to exit the roundabout calculated for each road user, a control signal for each road user as a message for the road user to communicate to the road user when and/or along which route the road user is to enter and/or traverse the roundabout;
managing, by the traffic control unit, resources of the roundabout, wherein the resources describe a lane or a partial section of the lane, on which the road user is to travel, and the message represents data of the resources that are to be used by the road user to travel on the roundabout such that the road user is matched with other road users;
assigning, by the traffic control unit, the road users one or more alternative routes for the roundabout in response to determining that a jam occurs on the roundabout and/or a preceding vehicle on the roundabout fails or has a breakdown, wherein the one or more alternative routes provide a lane change such that the flow of traffic through the roundabout flows without accident and in uninterrupted manner because the resources of the roundabout are adapted;
assigning, by the traffic control unit, a rank to each of the road users, wherein a priority and/or subordination with respect to at least one different road user results by the rank, and
transmitting the control signal generated for each road user,
wherein the control signal for at least one priority road user contains a first instruction for the at least one priority road user to enter the roundabout using a particular lane,
wherein the control signal for the road users other than the at least one priority road user contains a second instruction for the road users other than the at least one priority road user to wait, and
wherein, when the at least one priority road user follows the first instruction and the road users other than the at least one priority road user follow the second instruction, a waiting time for entering the roundabout of at least one priority road user is avoided.
