Urban transportation system is a large complex nonlinear system. It consists of surface-way
networks, freeway networks, and ramps with a mixed traffic flow of vehicles, bicycles, and …

It is explained why the set of the fundamental empirical features of traffic breakdown (a
transition from free flow to congested traffic) should be the empirical basis for any traffic and …

A nonlinear model-predictive hierarchical control approach is presented for coordinated
ramp metering of freeway networks. The utilized hierarchical structure consists of three …

Two traffic steams merging at a mainline-ramp intersection often leads to recurrent traffic
accidents, delays, oscillations and pollution. Existing literature shows that we still lack …

In this study, we propose and test through micro-simulation a novel controller for the
combined control of freeway traffic by adopting coordinated Ramp Metering (RM) and …

In this work, we apply the iterative learning control approach to address the traffic density
control problem in a macroscopic level freeway environment with ramp metering. The traffic …

Ramp metering, a traditional traffic control strategy for conventional vehicles, has been
widely deployed around the world since the 1960s. On the other hand, the last decade has …

An efficient humanitarian inventory control model and emergency logistics system plays a
crucial role in maintaining reliable flow of vital supplies to the victims located in the shelters …

This project has three objectives: 1) review existing ramp metering algorithms and choose a
few attractive ones for further evaluation, 2) develop a ramp metering evaluation framework …

Adaptive ramp metering has undergone significant theoretical developments in recent years.
However, the applicability and potential effectiveness of such algorithms depend on a …
