Open publisher page 0 citations

Abstract

This paper presents a new design method for acceleration lane in which the traffic volumes on main line of expressway and on-ramp are considered in the computating of the acceleration lane length. A group of computer simulated design lengths of acceleration lane are also provided for the purpose of comparison between varied methods and the traditional design standards. Finally the on-ramp metering is concerned according to the queuing theory and the threshold value inequality is given for the better control to the on-ramp traffic.
