In urban expressways, when an on-ramp and off-ramp pair are closely spaced, the
operational condition of the downstream diverge area influences that of the adjacent …

In ramp metering methods, the ALINEA algorithm is a very effective way and has been
applied widely. But the critical occupancy in ALINEA algorithm is often difficult to obtain and …

Lane assignment and on-ramp signal control are two potential methods for mitigating traffic
congestion of weaving segments. Unlike methods in the existing literature, where the …

The traffic operational efficiency of the urban expressway system will affect one of the entire
cities. Moreover, the idea that traffic control can improve the traffic operational efficiency of …

The traffic weaving area is one of the key bottlenecks affecting the operation efficiency of an
urban expressway system. The main motivation of this study is to explore the effects of lane …

Congestion has become highly recognized as a worldwide traffic problem, as traffic demand
has grown steadily over the past few decades. Variable speed limits (VSLs) are an …

Macroscopic traffic flow models are often applied as prediction models in proactive traffic
control strategies. For model calibration and validation, existing tests have been conducted …

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 …

During peak periods, bottlenecks are often triggered by excessive demand from both on-
ramp and mainline input flows. To relieve bottleneck severity and improve traffic safety, ramp …

At a metered on-ramp, a vehicle queue will be formed in front of the ramp meter when on-
ramp demand exceeds the ramp-metering capacity. It is therefore important to provide …
