  • 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.

  • The bus transfer system has been extended from Seoul to Gyonggi province to provide better Seoul metropolitan area transit service in September, 2008. Moreover, the curved bus routes, except existing rapid bus routes, which cause longer travel time have been straightened out. Also, the Skip Stop operation suggested by passengers has been introduced to main stops in the newly added express bus lines. This study surveyed passengers service satisfaction for the recent adopted bus policies such as the transfer discount system and the express bus system in Seoul Metropolitan area. The survey results may be important foundation for future strategies for improvement. The survey included questionnaires about the importance and the satisfaction level on both quantitative and qualitative factors. The results were statistically analyzed by the modified IPA (Importance-Performance Analysis). As the result of the survey, the newly adopted services such as fare system, fare discount on transferring, travel time savings and increased number of stops are economically feasible and satisfactory, whereas the accessibility to stops, ventilation and air quality in vehicles are the priorities to be improved. Also, the safety and the information system is in need of improvement.

  • This study analyzed passenger travel patterns especially for the transfer from metro to bus by using transit smart card data. We classified three types of land use such as residential, business, and shopping area where metro stations are located. The results show that more number of transfers was observed at residential area compared to that of shopping and business area. Also, more number of transfers from metro to arterial bus was observed than that of transfers to local bus. Further, the high number of transfers to arterial bus was observed at business and shopping area. This means that the transfer to bus at metro stations varies by land use. The egress walk distance from metro station was found to be approximately 400 meters and the average walk distance of young people was found to be shorter than that of the old.

  • The purpose of this paper is to identify unreliable routes in the view of users. After headway error ratio per route and travel time error ratio per route were calculated by using BMS data, reliability which incorporated two indicators each route was calculated through data envelopment analysis. Reliability among routes and among traffic zones was compared through the results, the needs to improve severely unreliable routes and to show passengers adjusted bus schedule information considering current reliability were suggested. As a future study, reliability evaluation framework of each route needs to be developed considering operation environment by analyzing bus card data (passengers and operation speed etc.) and pooly unreliable route should be managed strictly and reformed.

  • The operational purpose of exclusive bus lanes is to ease traffic congestion through the increase of person-carrying capacity on arterial roads. It is necessary to study on the route suitability for exclusive bus lanes because their operation may worsen traffic congestion due to the misuse of general purpose lane for an exclusive bus lane. This research quantifies the route suitability for exclusive bus lanes in Kwangju-city utilizing 7 indexes such as bus traffic volume, number of bus routes, traffic volume per lane, number of lane, number of intersection, number of streets, rate of curvature for the exclusive bus lane, recognizing the problem that the current installation standard of exclusive bus lanes is only limited to the bus traffic volume and the number of bus passengers. In addition, this research analyzes the operational efficiency for exclusive bus lanes, which is currently operated and their optimal operation hours.

  • As sustainable growth has been emphasized in the field of transportation, the railway system has been promoted as an environmentally-friendly transport mode. However, mode shifts from other transport modes to railway have been sluggish. In this context, to enhance the understanding of railway's competitive advantages and disadvantages, this research evaluates travelers'preferences for public transport modes for inter-regional trips: such understanding should make it possible to formulate effective policy for promoting railways. To this end, passenger recognition of competitive transport modes has been measured by applying multidimensional scaling analysis for six major inter-regional public transport services - KTX, ITX-Samaeul, Mugunghwa-ho, premium express bus, general express bus, and airline. As a result, we can conceptualize the recognition similarity in two-dimensional space, and understand how travelers perceive the six major transport modes.

  • In order to improve the existing evaluation system of bus services and gain more reasonable analysis outputs, the authors evaluate the efficiency of 113 arterial bus routes in Seoul in 2009 using a modified BCC model considering not only desirable outputs but also undesirable outputs. Each Decision Making Unit (DMU) is assumed to use inputs such as possession costs, operating costs, the ratios of median bus stops overlapped route lengths to produce estimates of desirable outputs (the number of passengers and service satisfaction score) and undesirable outputs (CO2 emissions). According to the analysis, the modified BCC model considering both desirable outputs and undesirable outputs shows more appropriate results. DMUs would be more efficient on average to reduce nearly 10% of the 3 inputs (possession costs, operating costs, and overlapped route lengths) and increase by about 160% the ratios of median bus stops. Also, a Tobit regression analysis is conducted to identify the most effective variables for maximum efficiency and discover that the variable of possession costs and the ratios of median bus stops are statistically significant.

  • Transportation policy to facilitate the public mode use is of the foremost importance to the local governments of Metropolitan Seoul, regarding the economic and environmental consequences of the increasing use of car. Understanding the travel behaviour is essential to the establishment of proper policy to guide more people to the use of public modes instead of private. The paper reports a result of sequential analysis of individual travel behaviour in Metropolitan Seoul, using a multi-dimensional motif search technique applied to Smart Card data that integrates individuals' different public mode uses. Groups of travel patterns with similar sequential information identified distinctive travel behaviour between Seoul north and south and between metro and bus uses. Travel patterns are more bounded within north Seoul and south Seoul respectively than crossing Han River between north and south. Within north and south, travel patterns visiting northern CBD and southern CBD, respectively, as well as their local neighbour in north and south, often use metro and metro-local bus combination, while travel patterns visiting only the north and south locals without CBDs more use only the local bus line and even only the areal bus line.
