Local Ramp Metering in Random-Location Bottlenecks Downstream of Metered On-Ramp

This paper studies a control strategy applicable to local ramp metering in the presence of random-location bottlenecks (RLBs) downstream of a metered on-ramp. With the support of the Highway Department of Victoria State, Australia, local ramp metering in the RIB case has recently been investigated, with the aim of designing appropriate and practicable control approaches. A related control strategy has been developed and tested in macroscopic simulation. This paper presents some representative testing results. This strategy has been incorporated into the HERO (heuristic ramp-metering coordination) freeway ramp signal control system and will be applied in Melbourne in the frame of a large-scale freeway upgrade project.
