This study presumes the efficiency of each route by utilizing data of Seoul's exclusive bus routes for the 2008 and the DEA model. In the estimation, it is assumed that the number of passengers and profits of each route is calculated by considering the number of buses and stops, travel distance, intervals and management cost. This study computed the efficiency scores of each bus line in Seoul based on the data for the first half of 2008 and one of the DEA models, namely the BCC model. After analysis using the input-oriented BCC model, out of a total of 18 lines of interest, there were 2 CRS lines and 16 IRS lines. Also, the Tobit Regression Analysis that helps identify the impact of the elements used in the analysis on efficiency scores proved that the most influential element to exclusive buses is the length of intervals.

It is necessary to evaluate methods for reasonable diagnosis for public transportation. However, previous studies have the problems in evaluation ground and propriety. Therefore, this research develop the method and equation for evaluating bus route considering interregional equity and route doubleness. This study developed in bus route evaluation method using Seoul bus Zone, and included the result of evaluation test using 199 route Seoul trunk bus (blue bus). Zone (0) (Jongno-gu, Jung-gu and Yongsan-gu) has the highest score in Evaluation result. Also this zone has good bus route, so it is easy to move to other Zone. It is possible to change and add the bus route to use the equation in this study, considering interregional equity.

This paper studies on the optimal bus network design in the framework of the set covering theory. The theory enables to cover passenger's loading and alighting areas as the set, and maximize the covering set as much as possible. In other words, it calculates the minimal set of the bus routes for covering whole bus passengers demand. After the optimal set of the bus routes is generated by the set covering theory, multimodal traffic equilibrium assignment is used for evaluating the generated set in terms of passenger's mode and route choice behavior. Whilst most previous works on it have been based on analyzing a specific route in a limited area, this study seeks to optimize the whole bus network.

The bus as a feeder trip should supply equality service to the whole community. But in spite of the change of latent demand to the bus by the variety of regional structural change, the existing bus route can not supply effective feeder service. For cope with the latent demand to the bus, this study establish a concept that frame the feeder bus route design system for changing of the existing bus route or creating of bus route. The concept of feeder bus route design system from this study is not to frame the whole bus network but to frame the single route to a unit OD pair. So, this study have assumption that do not consider the wating time at bus stop and transfer time. This system is consist of three phase. First is limitation of examination road network, second is enumeration of a most suitable route, and final is determination of the optimum bus route. However, a precondition is that the necessary time from the origin to the destination is brief, and having many demand.

대부분의 국가들이 노선버스의 운영을 공공부문에서 담당하고 있으나 우리나라를 비롯한 일부에서만 민간이 운영하고 있어 시민들을 위한 공익성만을 추구 할 수는 없는 입장이며 노선의 선정 또한 사업자와 공공이 협의하여 시행할 수밖에 없다. 이를 개선하기 위하여 버스노선 개편, 공동배차제 등 개선방안을 많은 지자체에서 시행하였지만 시민${\cdot}$업체${\cdot}$공공부문에서의 합의 도출은 지난한 상황이며 실행력이 없는 계획이 되고 있음을 여러 사례에서 볼 수 있다. Internet등 통신기술의 급속한 발달에 따라 통신을 통한 의사표출이 자유롭고 용이해지면서 일반지자체의 경우에 전체 민원 중 교통부문이 차지하는 민원이 $50\%$를 상회하고 있으며, 교통민원 중 $45.3\%$가 노선버스의 정시성 확보 및 운전기사의 불친절, 무정차 통과 등에 관한 것으로써 시민들이 가장 알고싶어 하는 사항이 버스의 실시간 운행상황임을 알 수 있었다. 따라서 본 연구에서는 실시간 버스정보제공을 통해 노선버스 이용자들의 대기시간 감소 및 이용편의를 증진시키고, 이를 통해 승용차 이용자를 대중교통수단으로 유도하여 대중교통을 활성화시키는 버스정보시스템(BIS ; Bus Information System)을 정립하며, 충주시 교통여건을 감안한 버스정보시스템 도입전략을 수립하고, 도입에 따른 기대효과를 분석하여 합리적이고 효과적으로 적용할 수 있는 지방자치단체 특히 충주시의 지능형 교통정보 시스템을 마련하는데 그 목적이 있다.

This study seeks to clarify the background and factors for the expansion of bus networks that connect Incheon International Airport with its hinterlands. For this research objective, this paper analyzes the relationships among the change of bus routes, competitive transportation modes, passenger fares, and the shortest time distance. Previously, the hinterlands of route bus networks that connect Gimpo International Airport were Seoul metropolitan area, Chungcheong region, Jeonju and Iksan in Jeollabuk-do(province). However, the opening of Incheon International Airport resulted in the expansion of the hinterlands of bus networks to Gangwon-do, Gwangju, and major cities in Youngnam region. Simultaneously, route bus networks also expanded in Seoul metropolitan area. Each bus route connecting Incheon International Airport with its hinterlands was opened by a single bus company or various bus companies. In many cases, due to the uncertainty of revenues or bus company's regional ties, a bus route was opened by various bus companies. In this paper, the analysis of the number of one-way route bus service and density of flight passengers shows that the frequency of the route bus service for Seoul except Gangseo-gu(ward) and for Seoul's satellite cities(Suwon, Seongnam, Anyang, Gunpo, Guri, and Osan) should be decreased. The analysis also shows that the frequency of the route bus services for the other cities, counties(Guns), and wards(gus) should be increased. In Seoul metropolitan area, although route bus fares are more expensive than subway fares, passengers use route bus more frequency than subway because time distance of route bus is shorter than that of subway and subway transfer is inconvenient. In general, outside Seoul metropolitan area, air flight is preferred in the regions that have airports. In contrast, the route bus is preferred in Daegu and other regions that do not have airports.

The convenient techniques for predicting the bus arrival time have used the data obtained from the buses belong to the same company only. Consequently, the conventional techniques have often failed to predict the bus arrival time at the downstream bus stops due to the lack of the data during congestion time period. The primary objective of this study is to overcome the weakness of the conventional techniques. The estimation model developed based on the data obtained from Bus Information System(BIS) and Bus management System(BMS). The proposed model predicts the bus arrival time at bus stops by using the data of all buses travelling same roadway section during the same time period. In the tests, the proposed model had a good accuracy of predicting the bus arrival time at the bus stops in terms of statistical measurements (e.g., root mean square error). Overall, the empirical results were very encouraging: the model maintains a prediction job during the morning and evening peak periods and delivers excellent results for the severely congested roadways that are of the most practical interest.

The guarantee of transportation for elderly and handicapped people is increasingly necessary owing to their growing social and economic activity. In March of 2013, a partial amendment to the law for transportation of the vulnerable was made by the government, to make more convenient transport a legal requirement. The amendment describes standards for the installation of transport facilities, and its support available. However, the adjustment of low-floor bus routes is not included. Therefore, low-floor buses are operating without consideration for the handicapped. This study evaluates the current low-floor bus system user experience by considering the residential distribution of vulnerable customers and analyzing their reasons for using public transport. As a result of this work, adjustments to current bus routes are proposed. The residential distribution of vulnerable people has been assessed using the supporting materials of the urban renewal project in Busan City, and their reasons for using public transport have been collected by a survey of the target user groups. The results show that group A, which has good accessibility, was in high demand, but provided the most limited service. Whereas group C, which also has good accessibility but was in low demand, provided its service most frequently. The data show the supply and demand inconsistencies of low-floor buses, and the inefficiency of bus route allocation. Therefore, this study proposes improvements to current methods for the effective operation of low-floor buses.
