The intelligent traffic systems are based on increasingly advanced and complex information systems requiring a rigorous design approach. In addition, the actors of various transport means have to work together, so it is necessary to ensure the inter operability of these systems. The synergies of this projects are one of the reasons why the local authority LMCU, the District-level Offices for Infrastructure (DDE, now the Inter-district Highways Offices, DIR) and the regional traffic information centre (CRICR) have collaborated more effectively by exchanging information. These three traffic managers are: the regional traffic information centre (Northern CRICR) which is responsible for the coordination of traffic management and roadinformation; Lille Metropolis Urban Community which is the local authority that manages signal-controlled junctions connected to the management system CARROSSE; and ALLEGRO (Agglomeration - Lille - Exploitation - Management of the Road) project which relates to the realization of a Traffic Management System over the urban expressways and motorways of the agglomeration, managed by the DDE (District-level Offices for Infrastructure in chargeof transport policy and planning activities in the North District). This road network covers 130 km (80 miles) in urban and suburban zones. It is ameshed network, inter-connected with the urban network including the principal structuring axes of the agglomeration, without motorway characteristics. To ensure effective operation, the approach ACTIF and the use of the tool OSCAR as catalyst were implemented. For the covering abstract see ITRD E139491.
