Systemic Evaluation of the HERO-Based Ramp Metering Algorithm Using Microsimulation: Demonstration Analysis Using a Sydney Motorway

Ramp meters impact not only the performance of the motorway, but also the performance of the arterial road network. The available literature on the HERO ramp metering system is used to implement it as closely as possible using AIMSUN Application Programming Interface (API). The implemented algorithm is evaluated using a network wide approach. In addition, a set of novel measures are introduced that facilitate the evaluation of the impacts of a ramp metering system on the entire network.
