Development of safety standard for Hi-pass: focusing the tubular markers

Although Hi-pass (an electronic toll collection system) has been operatedfor alleviating traffic congestion and enhancing mobility in expressways since 2000, there is no standard for safe operation. For that reason, tubular markers, which is a typical facility for safety in Hi-pass, were investigated. Tubular markers are installed for separating same or opposite traffic flows spatially, supporting the marks at a place, which has not only high possibility of accidents but requires particular care by drivers. Twoissues are considered in this study: one is prevention of accidents from the speed discrepancy of Hi-pass vehicles and others not using the technology; the other is guarantee of necessary distance for Hi-pass vehicles to change lanes on the exit ramp. Focusing those considerations, it is proposed not only proper distance of tubular markers at interchanges and main tollgates, but also fundamental basic subjects.
