The PRINT project seeks to permit a more green traffic flow in urban areas through reducing pollution from commercial trucks by giving priority andthereby reduce the numbers of stop and starts. The green intelligent transportation system (ITS) solution is based upon existing technology like detection, tracking and priority hierarchy within traffic light signaling. The adaptation and utilization to aid commercial trucks are however a new concept, that shows substantial potential with regards to reducing emissions and fuel consumptions. The next step in a proposed Norwegian development is to allow commercial trucks in priority lanes in urban areas instead of lining them up in queues. Signal priority and priority lanes combined are to be investigated in the PRINT project. An extension with a total concept embracing both priority as well as management may be the supreme solution to utilize green ITS and reducing emissions and fuel consumptions. Thispaper presents the setup in the PRINT Demonstrator 1 Priority of commercial trucks within coordinated signaling through the application of negotiated priority principle to special freight transport vehicle delivering post in Urban scenario. The project has equipped ten trucks from Posten Norway with onboard equipment identifying position and communicating with the overall management system for traffic light signaling. By requesting priority when passing virtual loops the commercial trucks can benefit from a smoother path through the area. The priority of commercial trucks is ubordinated priority of bus and trams in Demonstrator 1, but we will also look into other priority concepts by use of traffic simulation.
