Abstract
Abstract. Digital traffic management solutions are essential for the effective management of the continuing growth of road traffic. However, technical possibilities for implementing traffic management strategies by Traffic Control Centres are limited to a strategic network. At the same time, modern mobility apps from routing services offer road users many options to get informed and guided. The latter usually work independently from traffic management strategies of public authorities. Thus, different route recommendations not only lead to uncertainty of road users, but ultimately to a reduction in the effectiveness of the public traffic management strategies. A direct information exchange between both systems does not yet exist. This however would be a key to more efficient traffic management.City2Navigation therefore developed a technical concept for a nationwide implementation of a digital data exchange service (C2N service) to link public traffic management with routing services of private vendors. This service fills the gap between both group of actors, thereby serving as a crucial building block for digital traffic management in response to the goals of European and national frameworks for Intelligent Transport Systems (ITS).The C2N service not only promotes the cooperation of public authorities with private routing services, it also offers a variety of opportunities to develop new business models. It is a complement to C2C and C2X communication solutions in road transport, ultimately also enabling future possibilities for municipalities to conduct efficient and sustainable traffic management.
Highlights
1.1 Starting point: A lack of cooperationThe continuing increase in motorised individual and road freight transport, coupled with a growing awareness of its negative environmental and climate impacts, are challenging public traffic management.The possibilities for implementing urban traffic management strategies (TMS) by traffic control centres (TCC) are currently technically limited: For example, not all traffic lights can be controlled remotely, dynamic signposts and other information systems are only available along selected strategic roads and at selected points in the centres of major cities, and the possibilities to publish information as TMC messages are limited - both in terms of scope and quality of their information content (ISO, 2013)

Summary
The continuing increase in motorised individual and road freight transport, coupled with a growing awareness of its negative environmental and climate impacts, are challenging public traffic management. If municipalities, including small and medium-sized ones without traffic control centres, would be enabled to publish their traffic management strategies in a standardised digital form (spatial, temporal, intermodal, vehicle and trip purpose-specific), and the routing services would take up this information cooperatively, mutual synergy effects would be created contributing to increased efficiency in traffic management and provide better results for the individual road user. The route optimization for the individual user would move closer to the optimum of the overall traffic system, thereby increasing the efficiency of the entire transport system To facilitate such a cooperation, some technical requirements are needed which to date are not yet available in a wider scope:. - The TMS messages must be published in a standardized digital format, allowing for an automated retrieval and processing through routing services
