Green Priority (GP)
The objective of Green Priority is to increase punctuality of the services provided with designated vehicles and enhance traffic safety.
Taking into account various stakeholders’ views, a list of business model blueprints that address current or future challenges of urban areas, together with their operating and value-capture scenarios depicting the inner-workings of the business models, and the exchange of costs-benefits among stakeholders, have been created for the Green Priority service.
In Bordeaux the Green Priority service is implemented on a defined area containing five successive intersections approaching an hospital. The service provider is NeoGLS. In collaboration with Gertrude, when an RSU detects the presence of an equipped emergency vehicle, it forwards a priority request to the Traffic Light Controller, which will pass the lights to green at this traffic light, but also on the traffic lights ahead, to clear the way for the emergency vehicle until he reaches the hospital.
In Copenhagen the Green Priority service is based on direct ITS-G5 communication technology. Roadside Units (RSU) connected to the Traffic Light Controllers communicate directly with designated vehicles which have On-Board Units (OBU) installed. Upon arrival within a certain range, the OBUs signal the RSUs with the appropriate standards for messaging and communication and, if the timing is right, the vehicles receive a green light extension. This service is deployed for designated vehicles and in 7 intersections.
In Newcastle the Green Priority service is implemented via ITS-G5 technology. The service covers 18 signalized intersections on a key route heading north out of the city centre. Along with the GLOSA, it is used by Arriva express buses to enable more efficient fleet operation and more reliable journey times. Siemens UK is the service provider in collaboration with Newcastle City Council and Zircon (HMI designer).
In North Brabant the Green Priority service is based on ITS-G5 communication technology. This service covers a several signalized intersections of the busiest roads in the city of Helmond.
In Vigo the Green Priority service is implemented as proof of concept in a simulated environment with the aim to minimize the driving time towards their destination for designated vehicles when they are assigned a priority status over the general traffic.
