Post-Deployment Benefits from Auckland’s Active Ramp Signalling System

The NZ$22 million first stage of the Ramp Signalling project was installed by the New Zealand Transport Agency in 2007/08. It includes ramp signals on 35 ramps on the Auckland Motorway and uses the new SCATS Ramp Metering System (SRMS) algorithms developed by the New South Wales Road & Traffic Authority in Sydney as part of the SCATS traffic signal control system. There were 7 key goals and associated targets agreed for the system covering the areas of safety, efficiency and reliability, customer satisfaction, and the effects on the non-motorway arterial network. This paper describes the results of the analysis of initial data which shows the key benefits of the system so far, and discusses where improvements are planned which will be of relevance to all agencies looking to deploy or optimize such technology. The paper concludes by confirming that information from SRMS sensors and ARTIS can be used to optimize the ramp signals for both the motorway and adjacent SCATS signal controlled arterial network.
