A STUDY ON EFFICIENT OPERATION OF EXPRESSWAY HOV LANE SYSTEM THROUGH THE ANALYSIS OF DRIVING PATTERN OF VANS

摘要

This study attempted to derive the optimum standard to allow vans to use the HOV lane.As such, this study analyzed the traffic volume-speed relationships on the HOV lane andthe general lane, respectively, as well as the effect of traffic congestion in the general laneon the HOV lane. The analysis result showed that if the speed of vehicles on the generallane decreased, the ratio of the vans on the HOV lane significantly increased. When thespeed on the general lane decreased to less than 60 km/h, the vans changed the lane tothe HOV lane, which made the traffic volume of the vans greater than the traffic volume ofthe buses on the HOV lane. The result of lane travel cost calculation showed that the totaltravel cost is minimized when the van inflow rates are 75% (v/c=0.8) and 55% (v/c=1.0)
