Coordinated Ramp Metering for Freeways

Freeways were originally conceived to provide virtually unlimited mobility to road users. However, the continuous increase in car ownership and demand has led to a steady increase (in space and time) of recurrent and nonrecurrent freeway congestion, particularly within and around metropolitan areas. Freeway congestion causes excessive delays, increases fuel consumption and environmental polluti...

Modeling and PARAMICS Based Evaluation of New Local Freeway Ramp-Metering Strategy that Takes Ramp Queues into Account

One of the major criticisms of ramp-metering has been the delay caused on the ramps because of the queues created by ramp control strategies. However, recently, several researchers proposed strategies that explicitly take into account ramp queues when determining metering rates. In this paper, an isolated “feedback” based ramp-metering strategy using modeling is presented. In addition to the re...
