A 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 کاملQuantifying effects of ramp metering on freeway safety.
This study presents a real-time crash prediction model and uses this model to investigate the effect of the local traffic-responsive ramp metering strategy on freeway safety. Safety benefits of ramp metering are quantified in terms of the reduced crash potential estimated by the real-time crash prediction model. Driver responses to ramp metering and the consequent traffic flow changes were obse...
متن کاملRamp Metering and Freeway Bottleneck Capacity
This study aims to determine whether ramp meters increase the capacity of active freeway bottlenecks. The traffic flow characteristics at twenty-seven active bottlenecks in the Twin Cities have been studied for seven weeks without ramp metering and seven weeks with ramp metering. A methodology for systematically identifying active freeway bottlenecks in a metropolitan area is proposed, which re...
متن کاملFreeway congestion, ramp metering, and tolls
California freeway travelers suffer large and variable congestion delay. The delay is due to operational inefficiency, excess demand, and unforseen events. Operational inefficiency reduces speed and may cause queue spillovers that reduce exiting flows. Excess demand creates delay on ramps. Unforseen events such as accidents temporarily reduce capacity. The Cell Transmission Model of a freeway w...
متن کاملRamp Metering and the Capacity of Active Freeway Bottlenecks
The objective of this study is to determine whether ramp meters increase the capacity of active freeway bottlenecks, and if they do, how. The traffic flow characteristics at twenty-seven active bottlenecks in the Twin Cities have been studied for seven weeks without ramp metering and seven weeks with ramp metering. A series of hypotheses regarding the relationships between ramp metering and the...
