This paper summarises the findings of the DRIVE project CAR-GOES, which for the past three years has been investigated the integration of infrastructure-based dynamic route guidance systems with existing forms of urban traffic control. The research and development work has been accompanied by an investigation of the behavioural and ergonomic aspects of route guidance, leading to a clearer understanding of user requirements. The performance of different levels of integration has been studied, principally by simulation, for various types of dynamic route guidance, ranging from centralised to distributed (but excluding systems where route optimisation is performed in the vehicle), as well as various types of urban traffic control, ranging from fixed time to traffic responsive. Some attention has been given to multirouteing, which would be required with increasing rates of market penetration. The prediction of link travel times has been looked at, and the need for dynamic assignment coupled with the estimation of origin-destination flows, particularly under high market penetration scenarios, has been pointed out. The work has culminated in a coherent set of recommendations for system design.
