Road authorities traditionally use road side systems to perform their classic traffic management and traffic information tasks to inform road users. In various front-runner countries in the world cooperative systems are being developed. Cooperative Systems communicate and share information dynamically between vehicles or between vehicles and the infrastructure, to give advice or take actions with the objective of improving safety, sustainability and efficiency. These systems are on the verge of a breakthrough and many services will develop quite rapidly over the next couple of years to become ‘common reality’. With the advent of mature cooperative systems, road authorities are increasingly confronted with the question whether to keep investing in their existing solutions or to make their infrastructure intelligent. Several aspects play a role in this decision such as costs and benefits, return on investment, expected deployment of ITS, and legal and privacy issues. The main question of this project therefore is how road authorities need to position themselves to optimally benefit from changes in the field of cooperative systems and stay connected to the in-car developments.
