Abstract: A method of re-routing an autonomous vehicle operating on an initial pre-calculated route in an autonomous transportation network. The method comprises the detection of a perturbation regarding vehicle flow within a part of the autonomous transportation network by a first infrastructure element, the retrieval of at least one of a plurality of perturbation minimization strategies from a perturbation strategy memory based on the detected perturbation and the generation of perturbation information relating to the detected perturbation. The perturbation information or the perturbation minimization strategies are transmitted to at least one other infrastructure element in the autonomous transportation network and the perturbation information is transmitted from the one other infrastructure element to the autonomous vehicle. The autonomous vehicle follows an alternate pre-calculated route, wherein the alternate pre-calculated route is based on the received perturbation information.

Abstract: A method for parallel use of a reserved road space in a transportation network by a plurality of scheduled vehicles and a plurality of unscheduled autonomous vehicles is disclosed. The method comprises determining a route for the unscheduled autonomous vehicles travelling in the transportation network. The route is use for travelling from an origin to a destination in the transportation network. The method further comprises predicting conflicts for the unscheduled autonomous vehicles with the scheduled vehicles when travelling in the reserved road space. Predicting the conflicts is done using the selected route and items of the interaction data for the plurality of scheduled vehicles. The method also comprises generating conflict avoidance instructions for the unscheduled autonomous vehicles in order to avoid the predicted conflicts with the scheduled vehicles.

Abstract: A method of controlling a plurality of autonomous vehicles (20) entering a junction (56) from a plurality of inward routes (60a, 60b) and leaving the junction (56) in at least one outward route (65) is disclosed. The method comprises calculating a first time slot (80-1) for entering the junction (56) on a first inward route (60a) wherein the first time slot (80-1) has a first entry time at which the first autonomous vehicle (20-1) enters the junction (56) and adjusting the velocity of the first autonomous vehicle (20-1) by an onboard processor (27) such that the first autonomous vehicle (20-1) arrives at the junction (56) at the first entry time. A second time slot (80-2) for entering the junction (56) for a second autonomous vehicle (20-2) is then calculated. The second time slot (80-2) has a second entry time at which the second autonomous vehicle (20-2) enters the junction (56) and the second entry time is later than the first entry time such that the second autonomous vehicle (20-2) does not impact the first autonomous vehicle (20-1). The velocity of the second autonomous vehicle (20-1) is adjusted by the onboard processor (27) to arrive at the second entry time.
