For emergency, safety, environmental, traffic flow efficiency and Business reasons it is advantageous to give priority to specific classes of road user (at the moment no other then road users are considered but waterway crossings with roads may pop up at some time). The level of priority will depend on the type of user. At this moment an initial priority is recognizes resulting in the following current priority classification: emergency vehicles and motorcycles, public transport vehicles, special transportation such heavy goods vehicles, other vehicles.
The priority in each of the classes is further defined depending of the class. For instance emergency vehicles do have active emergency and passive emergency state while public transfer has may have more states, active duty or not and on time or not (with may be even some levels). As for this class difference states for the other classes are also defined. In this use case, all types of vehicles can request priority for an intersection or road section, and the traffic (light) controller determines in what way it can and will honour the request. Optionally, the requesting vehicle is informed about the action taken by the traffic light based on the request. This reply can be used to assist emergency vehicles in passing an intersection, but would also allow for heavy goods vehicles to calculate their fuel consumption reduction.
