Title: A vehicle prioritisation system
Inventor: DENNIS WITT
IPC: G08G1/16
Filed: 2016-04-19
Abstract: Characteristics of respective vehicles 2 are used to determine a priority for each vehicle such that movement of higher priority vehicles is prioritised over lower priority vehicles. Vehicles may transmit their respective characteristics and receive priorities determined for the own-vehicle or proximate vehicles, e.g. using vehicle-to-vehicle (V2V, Fig.5) or vehicle-to-infrastructure (V2I, Fig.3) communications. The priorities may displayed to drivers; used by the vehicles to give way autonomously to higher priority vehicles; or used to control the operation of traffic signals 112. The priorities may be determined by applying the characteristics to a policy. E.g. a policy may prioritise older and higher-emission vehicles to limit CO2 or NOX emissions; or promote car-sharing or electric vehicle use by prioritising such vehicles. If two vehicles have the same priority based on a first policy then the priority may be determined according to a second policy that is lower in a policy hierarchy. Alternatively priorities based on multiple weighted policies may be combined. The policies may be applied according to time of day or environmental conditions (e.g. current emissions concentrations).
