The coordinated ramp metering strategy aims to enhance the traffic flow on freeways by
integrating the effects of multiple on‐ramps. The success of this strategy depends heavily on …

Coordinated ramp metering strategies have been suggested as more effective measures
than local ramp metering when there are multiple congestion bottlenecks on the freeway …

The random nature of traffic conditions on freeways can cause excessive congestion and
irregularities in the traffic flow. Ramp metering is a proven effective method to maintain …

Ramp metering that uses traffic signals to regulate vehicle flows from the on‐ramps has
been widely implemented to improve vehicle mobility of the freeway. Previous studies …

Ramp metering has been broadly accepted and deployed as an effective countermeasure
against both recurrent and non-recurrent congestion on freeways. However, many current …

We present a novel ramp metering algorithm that incorporates multi-agent deep
reinforcement learning (DRL) techniques, which utilizes monitoring data from loop detectors …

Transportation agencies need to assess ramp metering performance when deploying or
expanding a ramp metering system. The evaluation of a ramp metering strategy is primarily …

To relieve freeway congestion during peak periods, ramp metering (RM) is often
implemented to control the input flow from onramps on freeways. Many studies focus on …

Over a period spanning more than 30 years, several ramp metering algorithms have been
developed to improve the operation of freeways. Many of these algorithms were deployed in …

In this paper, a probe‐based adaptive ramp metering approach has been developed and
compared with a detector‐based and pretimed ramp metering approaches using …
