Korean railroad has been accomplished the structural change through separating of facilities and operation of railroad in 2004. The existent government organization was transformed into the public, this caused problem of renovation of railroad management. Korean railroad has been the integrated management of passenger and freight. As putting the passenger service as a priority, freight transportation have fallen behind and not attained good sales results. Restructuring in Korean railroad would bring about considerable improvement, but still not come out of the deficit operation. To find a way out of this situation, there needs to make renovation and extend new enterprise. However, to operate the railway freight transportation more competitively, make up situation that can possess competitive power fundamentally. From this perspective, the purpose of this study is to analyze the necessity for separated operation of passenger and freight railway transportation. By doing this can expect to obtain the competition power of railway freight transportation, and is a help to build up the independent management system of railway freight transportation and secure competitive high position about other transportation systems especially road.

The purpose of this study was to investigate and analyze the perceptions of passengers on various topics related to passenger ship operation, by targeting the passengers (passenger ship consumers) at coastal passenger terminals in three regions, Incheon, Mokpo, and Tongyeong, where many coastal passenger ships operate in Korea. The survey period was October 1-October 11, 2019, just before the outbreak of COVID-19, and the number of samples was 277. The analysis was divided into two elements. Results of the analysis show that, for items islanders as well as the general public did not respond to more than 50% positively, a more in-depth review of policies and fare policies for transportation-disabled facilities through comprehensive fare evaluation such as the excellence of transportation-disabled facilities, the appropriateness of fares, and the appropriateness of fare guidance are necessary. It is expected that this study will contribute to the preparation for re-opening after COVID-19, as well as contribute to public transportation policy.

The survey period was from October 1 to October 11, 2019, just before the outbreak of Corona 19, and the number of samples was 277 The analysis was divided into two elements. As a result of the analysis, for items that both islanders and the general public did not respond to more than 50% positively, a more in-depth review of policies and fare policies for transportation-disabled facilities through comprehensive fare evaluation such as the excellence of transportation-disabled facilities, the appropriateness of fares, and the appropriateness of fare guidance. was found to be necessary. It is expected that this study will be able to prepare for re-opening after COVID-19 and be used in public transportation policy.

Due to implementation of legislations for translation poor such as handicapped people, elderlies, children most public buildings are now integrating barrier free design methods. However, barrier free design is still considered as constraints of physical elements that only serve to meet functional aspects for minors and conflict with designs of the space. The authors believe that it is time that barrier free design is considered not as constraints but opportunities that both meet functional and aesthetical needs serving the growing population of transportation poor and others as well. This paper has looked into characteristics of transportation poor and barrier free design elements of passenger terminals and developed 4 categories of design methods. applied by using human sense, form, furniture, and architectural elements. Then the authors analyzed Gunsan International and coastal passenger terminal existing conditions which is considered to be designed to meet barrier free guidelines and legislations through the developed design categories and elements. The result turned out that the subject in regard of barrier free designs for transportation poor lack various applications such as forms that can be used as symbolic and directional elements that assists as wayfinding cues. Also, flexible and multi functional approaches in furniture arrangements, structural approaches are needed.

In this paper, we present the study of a real passenger transportation system. Passenger transportation problem aims to transport passengers from bus stops to their destinations by a fleet of vehicles while satisfying various constraints such as vehicle capacity, maximum allowable riding time in a bus, and time windows at destinations. Our problem also has special issues such as mixed loading, consideration of afternoon problem together with morning problem, and transferring passengers between vehicles. Our solution approach consists of three serial procedures: bus route generation, bus scheduling, and post optimization. Efficient heuristic algorithms were developed and implemented for the procedures. The proposed solution approach has been successfully applied to several real world problem instances and could reduce about 10% to 15% of buses.

The purpose of this study is to implement concept of public to passenger ship route to promote benefits and adopt competition principle among ship companies to elevate business efficiency. As of year 2005, passenger ships operate in 106 routes departing from 10 harbors including Mokpo, Masan, and Inchonto provide transportation system to island residents. Contrast to other public transportation systems excluding some tourism routes, this essential passenger ship are unable to fulfill various customer services to the passengers due to stagnation or declination. In addition, route adjustment and flexible passenger ship operation are not expected due to private property right of the route. Therefore, establishment of public transportation system for remote island route is initiated for the connection between cities and islands, boost travel industry of island economy, and balanced growth oh the nation.

The greenhouse gas emission generated by idling vehicles is a critical issue in the greenhouse gas reduction from the transportation sector. Recently, the mandatory application of the Idle Stop and Go (ISG) for buses, trucks and taxis is in the process of legislation. Focusing on the regulation is about to apply to passenger cars, this study analyzed the quantitative economic effects of the ISG installation by passenger car types in Seoul metropolitan area to support proper policy making. The benefit cost ratio of ISG installation on commercial passenger car of Seoul is the most effective, calculated as 8.55. Accordingly, the amount of 660 liters (per year per vehicle) of fuel and 1,606 kg (per year per vehicle) of $CO_2$ could be reduced. The results of this study might be used as an index for judgment of policy such as determining appropriate subsidy for ISG installation on passenger cars.

Service is the source of firm's competitive advantage in recent years. The importance of service quality in any service industry doesn't need to be disputed. Customers have expected the improvement of the quality of service they receive ,so providers are struggling to meet these expectations. This study aims at finding factors of service quality in passenger transportation. An empirical investigation and the measurement on the perceived Service Quality by customers in the passenger transportation system was carried out. The purpose of this study is to clarify the factors of service quality on the basis of service marketing concept. In order to fulfill the objectives, this paper combines research tools that include both empirical study and documentary research. Data was gathered from 239 passengers by the use of questionnaire. In this study, the established hypotheses were generated on the basis of the service quality evaluation (SERVQUAL) model. Research findings through empirical test are as follows. First, five service quality dimensions in passenger transportation are identical to SERVQUAL dimensions defined by Parasuraman, Zeithaml, and Berry in 1988. Second, demographic segments such as gender and age don't have significant different dimension of service quality. Third, there is no significant difference between groups by experiences such as price level, abroad tour and vehicle type in determinants of transportation service quality.

Korea's air passenger traffic has been growing steadily. In this paper, we propose a forecasting model of air passenger demand to ascertain the growth trend of air passenger transportation performance in Korea. We conducted a simulation based on System Dynamics with the demand as a dependent variable, and international oil prices, GDP and exchange rates as exogenous variables. The accuracy of the model was verified using MAPE and $R^2$, and the proposed prediction model was verified as an accurate prediction model. As a result of the demand forecast, it is predicted that the air passenger demand in Korea will continue to grow, and the share of low cost carriers will increase sharply. The addition of the Korean transportation performance of foreign carriers in Korea and the transportation performance of Korean passengers due to the alliance of airlines will provide a more accurate forecast of passenger demand.

We propose a method to find flows of transit users in the subway transportation network of the metropolitan Seoul and analyze the passenger flows on some central links of the network. The transportation network consists of vertices for subway stops, edges for links between two adjacent subway stops, and flows on the edges' Each subway transit user makes a passenger flow along edges of the shortest path from the origin stop to the destination stop in his trip. In this paper, we have developed a new algorithm to find the passenger flow of each link in the subway network from a large trip-transaction database of subway transit users. We have applied the algorithm to find the passenger flows from one day database of about 5 million transactions by the subway transit users. As results of the experiments, the travel behavior on 4 central subway links is analyzed in passenger flows and top 10 flows among all subway links are explained in a table.
