A new heuristic traffic-responsive feedback control strategy HERO (HEuristic Ramp meteringcoOrdination) that coordinates local ramp metering actions at freeway networks is presented. Theproposed coordination scheme is simple and utterly reactive, i.e., based on readily available real-timemeasurements 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 newstrategy overcomes the problem of uncertain freeway capacity by targeting the critical occupancy formaximum throughput. HERO outperforms uncoordinated local ramp metering and approaches theefficiency of sophisticated optimal control schemes.HERO has been implemented by VicRoads at 6 consecutive inbound on-ramps on the MonashFreeway in Melbourne, Australia. This pilot project was part of the Monash-CityLink-West GateUpgrade (MCWU) Project. The obtained results show an increase of traffic throughput and a reductionof travel times. In order to maximize the performance across the entire 75 km route of the MCWUProject, HERO is currently under implementation at 58 more on-ramps.
