Create as it were a shopping list of problems they want to solve, and of services they want to have. EITs themselves are best informed about their countries geographical and social features. Aspects that definitely affect the choice of ITS-applications. DGs should develop their own ITS architecture, taking advantage of the experience of the DDs in this area. How the different services work together What sort of system should be used This approach offers the perfect way to find out who the stakeholders are, their roles, their participation, their partnership, their responsibilities must be clear from the beginning.
Next step is the working out the system design.
Local characteristics definitely affect the choice. The EITs will have to use their local knowledge. Institutional issues, users needs and expectations come first, coordination and management next, and then the choice of systems follows logically. DDs should help DGs to get up on the learning curve. Start with ITS applications where the DGs can get proper operational support, and where the DGs can train their own staff.
