  • The electronic toll collection system(ETCS), is globally used in about 40 countries. In Korea, the Korea Expressway Corporation led the nationwide introduction of the ETC system in 2007 under the brand name of the Hi-pass. Since then, Hi-pass, with its rate of average daily use reaching about 70%, has become an essential facility in Korean expressways. To identify users' perception on Hi-pass (satisfaction, preference, etc.), this study conducted a Modified Importance-Performance Analysis (M-IPA). With this, this study attempted to identify the kind of efforts necessary to enhance current Hi-pass users' convenience and satisfaction. According to the result of M-IPA, the items including "non-stop payment" and "toll discount" are identified as key items that require further improvement. For improvement in the "non-stop payment" item, operations of Hi-pass toll booths appropriate for the demand for Hi-pass use and the selection of Hi-pass booths' locations in consideration of entry and exit lanes need to be improved. In addition, with regard to the "toll discount" item, although toll discount is currently provided to Hi-pass users, thus, PR thereof will have to be strengthened. It is expected that this study will be used as basic data to devise methods of enhancing Hi-pass usage through improvement of Hi-pass users' satisfaction.

  • Currently average daily traffic using Hi-pass has increased over 3 times that of 2008 and more than half of highway traffic now uses High-pass. At this juncture, reassessment on the overall operation of Hi-pass is required to improve the safety aspect of toll booths and the flow of traffic. Although existing Hi-pass operation manual presents the methods of alignment, they do not reflect actual forms of vehicles and do not properly take the safety of toll booth and flow of the traffic into consideration. In order to compensate these problems, this study classifies highway tollbooths into two categories of mainline type and interchange type, and establishes the standard of lane alignment by traffic conflict analysis based on the types divided according to geometric structure or environment around the tollbooths. In addition, traffic flows around the tollbooths were reflected with the stage to arrange Hi-pass lanes according to the volume of traffic on the lanes for Hi-pass.

  • It is rapidly increasing number using Hi-pass system passing through tollgate on the high way. However disabled people and man of merit have been excepted existing advantage of discount when they are using Hi-Pass. It is difficult to make a check an advantage when they are in a vehicle for using Hi-pass system technology in present. For solving this problem, we have fabricated virtual Hi-pass system combined fingerprint identification system (FIS) by AVR and fingerprint identification USB. We checked the chance of efficiency and utility in this system for getting a solution of conservative problem. And, it will be also used for entrance ticketing and transferring of cave tourism and so on.

  • Since the percentage of vehicles equipped with Hi-pass, an electronic toll collecting device, has increased rapidly, it is very crucial to determine the optimal location of Hi-pass lanes at a toll plaza in terms of traffic control and operation. In this study, the appropriateness of existing Hi-pass lanes of a toll plaza is evaluated considering its physical geometry and traffic characteristics. A new evaluating criterion called "traffic dispersion rate" is developed in order to measure the level of traffic spreading across the toll booth lanes at a toll plaza. Logistic regression models are constructed to estimate the relationship between the traffic dispersion rate and its affecting variables. The model estimation results show that several variables including Hi-pass lane traffic volume, length of toll plaza, entering/exiting taper lengths, and locations of Hi-pass lanes. The results also suggest that traffic dispersion rate can be increased by adjusting the location of Hi-pass lanes. The study enables us to quantify traffic dispersion rate which can be used to optimize the location and operation of Hi-pass lanes at toll plazas.

  • Although Hi-pass have been operated for alleviating traffic congestion and enhancing mobility in expressways since 2000, there is not any standard for safe operation. For that reason, we investigated about tubular markers, which is a typical facility for safety in Hi-pass. 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 distinguished carefulness of drivers. In this paper, it is noted two considerings; one is prevention of accident from the speed gap of autos and Hi-pass vehicles; the other is guarantee of necessary distance that Hi-pass vehicles could be changes the lanes for off-ramp. Focusing those considerations, it is proposed not only prefer distance of tubular markers, but also fundamental basic subjects. We anticipate that the results of this study would be useful reference in more safe and efficient tollgate operation of Hi-pass.

  • The existing HiPassPlusCard system is composed of the HiPassPlusCard, a Purchase SAM, a Purchase terminal, a settlement system and OBU. However, this system is confronted by the problem with its incompatibility. This problem occurred because the technology companies made cards in their own ways in respect of the parts which were not yet set by KS standard. Thus if existing HiPassPlusCard user wants to use any other public transportations, user would have to buy other cards and have to bring all them. Also if the HiPlusCard wants to extend their business to apply its technology into infrastructure of the other companies, the HiPlusCard has to construct infra independently so that it causes the such problems of duplicated investment. To solve these problems, we have analyzed and upgraded the existing HiPassPlusCard system, and we designed and developed the Nation-wide Interoperable HiPassPlusCard system. Then the conformity test demonstrated that it is efficiency-oriented and technically performs well. Also we, the HiPlusCard, the Korea Financial Telecommunications & Clearings and the KORAIL NETWORKS, run the Test-bed in Gwangju for 6 months. The test-bed indicated that Nation-wide Interoperable HiPassCard system practically works well.

  • 본 논문에서는 교통 이력자료의 시공간 데이터를 활용하여 교통 분석 및 예측에 필요한 신뢰성 높은 데이터를 제공하기 위한 TCS/HI-PASS 전처리 알고리즘을 제안한다. 시공간 데이터의 전처리 알고리즘은 각종 교통정보에 이용되고 있으며, 그 중 대표적으로 활용되고 있는 것이 차량 검지기(VDS)를 통해 수집된 교통량, 속도, 점유율 정보이다. 이러한 정보에 가공처리 알고리즘을 적용하여 공간평균속도 기반의 통행시간을 산정하고 있으며, 고속도로 통행료 수납시스템(TCS)으로 부터는 출발영업소와 도착영업소의 진 출입시간을 기반으로 평균통행시간을 산정하고 있다. 본 연구에서는 차량 검지기(VDS) 데이터와 기존 TCS 데이터의 전처리 알고리즘을 분석하여 TCS와 HI-PASS 데이터 기반의 개선된 전처리 알고리즘을 설계, 구현하였다.

  • Safety improvement has been a continuous challenge, especially at toll gate of express highway where traffic conflict often occurs due to frequent lane change by drivers of "Hi-pass" lane and regular "TCS" lane. As a part of research on safety at toll gate, this study videotaped traffic conflict data between vehicles using centrally located "Hi-pass" lane and regular "TCS" lane and analyzed accident risk. According to the correlation analysis of vehicle speed, relative vehicle speed, and sudden vehicle deceleration rate due to traffic conflict, when the relative vehicle speed between centrally located "Hi-pass" lane and regular "TCS" lane increases, sudden vehicle deceleration rate also increases. One of the findings is that centrally located "Hi-pass" lane at toll gate shows different location for traffic conflict, and frequency of traffic conflict and the relative vehicle speed was also different based on vehicle lane use. TA (Time to Accident) analysis shows that accident rate is high at toll gate where Hipass lane is installed in center lane, when the occurrence of sudden vehicle deceleration and deceleration time of vehicles rise for vehicles on "Hi-pass" lane. Furthermore, if the expressway entrance/exit point is closely located to toll gate, TA showed a low value. Thus, it is necessary to reduce the relative vehicle speed in order to improve safety. The Study presents reduction of the relevant vehicular speed and prevention of accidents at the centrally installed "Hi-pass" lane as an important strategy for safety improvement at toll gate.
