A Novel Parameter for Ramp Metering and Evaluation

Real and scientific traffic flow parameter are the basis to make efficient traffic control strategy and establish control function and this will leads to an appropriate and impartial reflection to efficiency and equity of control property. Intelligent control is a new development where the control problem is to find the combination of control measures that result in the best road performance and control effectiveness. The problems of intelligent metering evaluation for local ramp are considered. In this paper, a novel ramp queuing parameter-the reduplicated waiting time was posed using the queuing theory. With in-situ traffic flow data, comparison between the novel and previous parameters are made to clarify the advantages of the novel parameter.
