FTMS, TCS, ITS equipment such as high-pass highway are just a situation that does not lack traceability and passive surveillance is related to fault DB has so far consisted of an integrated operations management to maximize utilization of the facility. In addition, there is no replacement parts are replaced when a failure occurs, increasing the number of parts and repair time I have trouble growing, and becoming a service interruption whenever you replace each time. In this study, proactively manage the failure history of a highway facility ITS tries to preventive maintenance. Therefore, the error history is based on the reliability of the high-pass facilities theory to calculate the reliability of the system through a systematic statistical analysis Operational Availability. The fault number and the time the replacement period through the estimate decreases and can reduce the budget expenses by securing the spare parts quantity, establish a management plan in part by improving the quality of the system through constant preventive maintenance, quality of service at all times It may direct the non-stop operation state of the available state.

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 result, in case of entry/exit toll there were 21.0~56.4ml/veh fuel consumption savings, in case of open toll fuel consumption savings was analyzed as 10.5~28.1ml/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%.

PURPOSES : This investigational survey is to observe a proper spatial aggregation method for path travel time estimation using the hi-pass DSRC system. METHODS : The links which connect the nodes of section detectors location are used for path travel time estimation traditionally. It makes some problem such as increasing accumulation errors and processing times. In this background, the new links composition methods for spatial aggregation are considered by using some types of nodes as IC, JC, RSE combination. Path travel times estimated by new aggregation methods are compared with PBM travel times by MAE, MAPE and statistical hypothesis tests. RESULTS : The results of minimum sample size and missing rate for 5 minutes aggregation interval are satisfied except for JC link path travel time in Seoul TG~Kuemho JC. Thus, it was additionally observed for minimum sample size satisfaction. In 15, 30 minutes and 1 hour aggregation intervals, all conditions are satisfied by the minimum sample size criteria. For accuracy test and statistical hypothesis test, it has been proved that RSE, Conzone, IC, JC links have equivalent errors and statistical characteristics. CONCLUSIONS : There are some errors between the PBM and the LBM methods that come from dropping vehicles by rest areas. Consequently, this survey result means each of links compositions are available for the estimation of path travel time when PBM vehicles are missed.

This study is to analyze the impacts of different High-Pass lane speed limits. Paramics, microscopic simulation software, was used to perform microscopic simulations. For the simulations, Incheon toll gate traffic count data was used. The Paramics simulation results show that higher High-Pass speed limit (70Km/h) produced better traffic flow condition and less air pollution cost compared to existing High-Pass speed limit (30Km/h).

본 연구는 지속적인 교통량의 증가로 인해 발생되고 있는 고속도로의 혼잡을 해결하기 위해 한국도로공사에서 도입, 시범사업을 실시하고 있는 자동요금징수시스템의 효과를 분석하고자 한다. 이를 위해 하이패스라고 하는 자동요금징수시스템의 시범운영이 실시되고 있는 서울외곽순환고속도로의 판교, 청계, 성남 톨게이트를 대상으로 정량적 측면과 정성적 측면에 대해 시범사업 시행 전.후의 상황에 대해 비교.분석하였다. 시행 전.후를 비교해 본 결과, 정량적 측면에서 각 톨게이트 별 시간대별로 다른 결과를 보이긴 하지만 이용율이 비교적 높은 오전 첨두시에는 3개 톨게이트 모두 효과가 있는 것으로 나타나, 일정수준 이상의 이용율이 있는 경우는 효과가 있는 것으로 분석되었다. 정성적 측면의 이용자 만족도 조사에서는 하이패스 이용자의 84%가 만족하는 것으로 나타났으며 비이용자 선호도 조사에서는 응답자의 91%가 하이패스 이용의사가 있는 것으로 조사되어 효과가 있는 것으로 분석되었다. 결론적으로 7,000대의 단말기 과소 보급으로 아직까지는 평균 3.9%의 저조한 이용율을 보여 시범사업의 전반적인 사업효과가 제대로 나타나지 알고 있지만, 비교적 하이패스의 이용율이 높은 오전첨두에는 효과가 있는 것으로 나타난 점을 보아 2000년 12월부터 시행되고 있는 단말기의 추가 보급이 완료되는 시점에는 그 효과가 분명하게 나타날 것으로 예상된다. 따라서. 이용자의 만족도와 비 이용자의 선호도가 매우 높은 상황에서 현재의 시범운영상에서 발생된 문제점을 개선하여 하이패스를 확대.보급한다면 고속도로의 혼잡을 해결할 수 있는 좋은 방안이 될 것으로 판단된다.

This paper proposes Electronic Credit Card(EMV) processing procedures for a credit payment method which can be applied to Korean ETCS(Electrical Toll Collection System). In Korea, Korea Highway Corporation services contactless ETCS's called by Hi-Pass and Touch-Pass system at present. These systems operate on a pre-paid payment method similar to electronic money. On the other side, a credit payment method based on credit card has an advantage which does not require pre-paid. The introduction of credit payment method to ETCS is in preparation. In this paper, we propose EMV processing methods based on a credit payment method which can be applied on ETCS.

Smart tolling, which improved the drawbacks of the existing high-pass system, was developed and built through the Smart Highway R & D project in 2007. In order to successfully introduce and spread Smart Tolling, it is need to analyze factors that affected by intent to use. This study conducted research based on literature studies and empirical studies, and developed a research model to analyze factors affecting the users' intention of smart tolling system based on technology acceptance model (TAM) and value based acceptance model. The main variables of the research model are service characteristics (convenience, reliability), technical characteristics (flexibility, stability), environmental characteristics (switching cost, effectiveness of policy) and intention to use. To test the hypotheses set in this study, frequency analysis, exploratory factor analysis, and confirmatory factor analysis were performed using the SPSS 22.0 program statistical package and AMOSS 18.0. The convenience and reliability presented by service characteristics did not affect the intention to use of smart tolling service.
