Effect of Passenger Car Fuel Consumptions and Fuel Cost Savings by Hi-Pass System

ABSTRACT The high-pass(brand name of Electronic Toll Collection System) utilization trend on the highway continues to grow as 59.4% (by the end of 2013). In this study, we applied the carbon balance method using a fuel chassis dynamometer with the four passenger car classes in order to measure the fuel consumption of the car using the expressway tollgate. We experimented 18 driving mode at general tollgate and high-pass tollgate. As a r esult, in case of entry/exit toll there were 21.0~56.4 ㎖ /veh fuel consumption savings, in case of open toll fuel consumption savi ngs was analyzed as 10.5~28.1 ㎖ /veh . In addition, the annual fuel cost savings by virtue of high-pass was 28.2~57.3 billion won at 70% utilization rate, 32.2~65.5 billion won at 80%, 36.2~73.7 billion won at 90% and 40.3~81.9 billion won at 100%.Key words : Hi-Pass, Fuel Consumption, Fuel Cost, Fuel Chassis Dynamometer , Carbon Balance Method * 주저자 : 교통안전공단 자동차안전연구원 책임연구원 ** 공저자 및 교신저자 : 단국대학교 토목환경공학과 교수*** 공저자 : 교통안전공단 자동차안전연구원 선임연구원† Received 3 December 2014; reviewed 11 December 2014; Accepted 26 January 2015
