Vehicle, traffic center and infrastructure are three independent entities of our roads. The aim of cooperative mobility systems is to link these actors allowing vehicle to interact locally and directly with traffic control equipment in order to collect real-time data and to provide services for the drivers. Important barriers for the deployment may exist: legal and liability issues, stakeholders' interaction, investment costs and user acceptance. This paper presents a compromise taking into account all these topics by describing technical aspects of traffic information routing from the traffic center to the final user and vice versa. The originality of this work lies on an evolution in the use of Datex II, a communication protocol between centers, extended to roadside units. Conversion steps from an infrastructure-to-infrastructure message to an infrastructure-to-vehicle message will be emphasized. Experimental results on circuit test and open roads will also be included.
