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...
متن کاملCoordinated Ramp Metering and Intersection Signal Control
The operations of freeway ramp metering and urban traffic network signal control are independent in most areas. Such situation may cause some conflict between traffic streams of the two subsystems, or, at least, their dynamic interactions have not been taken into account from an overall system viewpoint. Traffic performance can be improved if the controls of these two subnetworks are integrated...
متن کاملEffects of on-ramp and off-ramp metering on queue forming in urban traffic networks
To control the traffic flows near on-ramps and off-ramps, ramp metering installations can be used. We compare on-ramp metering and off-ramp metering, with respect to queue forming and total time spent. Both control measures are used to improve traffic flow on freeways, and both have influence on the route choice of the drivers. Although the two measures are very similar, there are some major di...
متن کاملA Vissim Based Framework for Simulation of Cooperative Ramp Metering
Due to the increase of vehicle numbers in recent decades, there exists a significant problem of reoccurring road traffic congestion. Such congestions are a characteristic of densely populated urban areas. They occur daily during the morning and afternoon rush hours. The road traffic congestion problem can be solved by applying new traffic control approaches from the domain of intelligent transp...
متن کاملApplication of Variable Speed Limits and Ramp Metering to Improve Safety and Efficiency of Freeways
Research recently conducted at the University of Central Florida involving crashes on Interstate-4 (I-4) freeway in Orlando, Florida led to the creation of new statistical and neural networks models that are capable of determining rear-end and lane-change crash risks along the freeway in real-time. For determining the rear-end crash risk, it was found that rear-end crashes occur within one of t...
