In September 1990 the motorway orbiting Amsterdam was completed. This ring road together with some connecting highways, offer a number of alternative routes. For instance, travelling from Zaanstad to Utrecht, there is a choice to be made between the Coentunnel and the Zeeburgertunnel. The availability of these alternative routes offers possibilities for guiding the traffic dependent on the actual demand and supply of infrastructure. Available techniques are: variable direction signs, variable message signs and route guidance systems. The complex situation, together with the high traffic volumes and the route choice behaviour make it difficult to estimate the effects of the different types of guidance on the traffic. In this study the dynamic traffic simulation model DYNDART, as developed by INRO-TNO, has been used to evaluate the different types of guidance of the traffic on the performance of the network.
