Assessing Ramp Metering and Variable Speed Limits Strategies for Auckland Motorway

Ramp metering (RM) and variable speed limits (VSL) are two important ITS tools aimed at improving performance of motorway systems. The former is widely used all around the world to regulate on-ramp traffic while the latter is an emerging technology that can be deployed in the mainline immediately upstream side of on-ramps to create some merging space for entering traffic. This paper assesses the performance of two ramp metering algorithms namely ALINEA and HERO individually and in combination with VSL strategies for a critical bottleneck section of Auckland Motorway using AIMSUN micro-simulation. ALINEA is the most prominent local RM algorithm while HERO is a rule-based coordinated RM algorithm. The performance was evaluated based on two important performance indicators namely total time spent and Gini coefficient representing the efficiency and equity of the motorway system respectively. Results show a potential to improve the motorway performance using a combination of these tools.
