Samenvatting
Implementation is well advanced on the roll out of ramp signaling across the whole of the urban motorway network of Auckland. This is an extension of the Advanced Traffic Management Systems (ATMS) initially launched in 1999. Auckland is a region with a population of 1.3M. The urban motorway network is only 120km long but has an average daily trip demand of about 900,000 movements across 50 interchanges. Ramp signaling is proposed for all on-ramps and for some motorway to motorway links. The paper places emphasison the procurement of the services required to implement ITS based projects using external resources.
