Purpose-On-ramp merging areas are typical bottlenecks in the freeway network since
merging on-ramp vehicles may cause intensive disturbances on the mainline traffic flow and …

This article presents a study on freeway networks instrumented with coordinated ramp
metering and the ability of such control systems to produce arbitrarily complex congestion …

This article describes a coordinated ramp metering algorithm for systematically mitigating
freeway congestion. A preemptive hierarchical control scheme with a three‐priority‐layer …

The term breakdown of flow at a freeway bottleneck location has been used to describe the
transition from relatively free-flowing traffic to congestion, often called stop-and-go traffic, but …

The recently developed traffic-responsive feedback control strategy HERO (heuristic ramp
metering coordination), which coordinates local ramp-metering actions in freeway networks …

Ramp metering has been found to improve traffic conditions on the freeway mainline by
breaking the platoons of ramp vehicles minimizing turbulence at the merge locations. The …

Connected vehicles control has brought the opportunity of using a higher level of Traffic
Management Center (TMC) to investigate the driving-related terms of congestion avoidance …

Various traffic management strategies have been developed to alleviate the congestion on
freeways. The equity issue has been considered as one of the major challenges for the …

Aiming at the problem of mainline congestion and ramp queue spill in urban expressway, an
optimized on-ramp control method based on reinforcement learning is put forward. Online …
