Content SummaryA new heuristic traffic-responsive feedback control strategy HERO (HEuristic Ramp metering coOrdination) that coordinates local ramp metering actions at freeway networks is presented. The proposed coordination scheme is simple and utterly reactive, i.e., based on readily available real-time measurements without the need for real-time model calculations or external disturbance prediction. HERO employs an extended version of the feedback regulator ALINEA at a local level. The new strategy overcomes the problem of uncertain freeway capacity by targeting the critical occupancy for maximum throughput. HERO outperforms uncoordinated local ramp metering and approaches the efficiency of sophisticated optimal control schemes. HERO has been implemented by VicRoads at 6 consecutive inbound on-ramps on the Monash Freeway in Melbourne, Australia. This pilot project was part of the Monash-CityLink-West Gate Upgrade (MCWU) Project. The obtained results show an increase of traffic throughput and a reduction of travel times. In order to maximize the performance across the entire 75 km route of the MCWU Project, HERO is currently under implementation at 58 more on-ramps. en
