This paper reports on the trial of the Easy Merge Ramp Signal (ramp metering) that commenced on 1 March 2004 at the Mahunga Drive northbound on-ramp on SH20. This is one of the first ramp metering trials in New Zealand. Evaluation of this trial concluded that ramp metering has successfully improved the traffic performance of the road network within the vicinity of the ramp metering site. Traffic throughput (network wide) and travel speed (SH 20) were significantly increased. It is already evident that the success of this trial has introduced ramp metering as a very useful traffic management tool in New Zealand. Transit New Zealand has prioritized Travel Demand Management projects in Auckland as its top three national projects. Ramp metering is seen as one of the main traffic management tools available to achieve travel demand management outcomes.
