The accurate forecasting of the public transportation's transit and arrival time has become increasingly important as more people use buses and subways instead of personal vehicles under the government's public transportation promotion policy. Using bus management system (BMS) data, which provide information on the real-time bus location, operation interval, and operation history, it is now possible to analyze the bus schedule reliability. However, the punctuality should always be considered together with the operation safety. Therefore, this study suggests a new methodology to secure both reliability and safety using the BMS data. Unlike other studies, we calculated the bus travel time between two bus stops by dividing the total travel length into 6 sections using 5 different measuring points. In addition, the optimal travel time for each bus route was proposed by analyzing the mean, standard deviation and coefficient of variation of the each section's measurement. This will ensure the reliability, safety and mobility of the bus operation.

A sudden increase of old people's free urban railway transportation resulted from the acceleration of aging trend causes the chronic deficit. As continuous deficit caused by the free urban railway transportation of old people is expected, a fairness problem about the fare system of using public transportation is issued because only the urban railway provides free-rides to them, which is contrast to bus-riders paying full payments. Therefore, the study intends to draw an alternate to solve the problem of the free urban transportation uses by calculating an appropriate fare ratio between the two transportation modes, which is expected to alleviate the fairness issue between the urban railway and the bus.

For Improving gradually inferior environment of public transportation system, it is necessary to introduce new transit System(NTS). NTS is defined as automated economicm system for it's operation . The Track Guided Bus System (TGBS) is one of the NTS, which is possible operating on the track or road surface and the system has actually many advantages. This study was concentrated on investigating the characteristics of TGBS, comparing to the other public transportation system and appraising the advantages of it on the benefit of the passenger side as well as investor, and then suggested applicable routes. As the result of the study, it is concluded that the advantage of this system is less transfering and initial low investment. Applicable route is the demand of passengers in the range of PPHPD 5,000~39,600, which is more than bus but not more than subway.

Until now, the carriage's design has been performed by built-carriage engineers in urban railway company without the notion of railway design. Furthermore, there is no prominent change the shape of exterior and interior design between the 1970's trains and the latest one. In terms of the notion of interior space, there are a lot of differences between Oriental and Western, also region of each countries. Especially, Among Orientals, Korean is not good at utilizing the small space and react effectively as compared to Japanese. Therefore, the interior space of public transportation needs to be relatively developed to highly reasonable level in Korea. The purpose of this paper is to apply vernacular design elements for developing interior design in Korean lightrail, which is the next generation public transportation. In order to develope ideal interior design, the interior layout in carriage considers the emotional aspect as well as functional one. Also, the research of vernacular design in urban train can provide national character and traditional design and can make a success in a practical use and a visual effect. This study focused on the application of vernacular design elements for developing the design-processed model will be proposed the outline of interior layout and the shape of interior trims in the public transportation in Korea.

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System provides third-party verification for environmentally sustainable construction. But while LEED-certified buildings provide healthier work and living environments, Previous studies have shown that LEED certification does not provide any direct economic incentives to owners and developers. To address this issue, this study aims to investigate the economic benefits of LEED criteria. The objective of this study is to examine whether or not there is a significant correlation between median household income and the number of bus stops and light rail stations for a given parcel that meet LEED sustainable site criteria for public transportation access. The findings showed that the number of bus stops had a positive correlation with median household income, which means that more bus stops a given parcel had that met LEED criteria, the greater the median household income of a block group where the given parcel was located would be, though this positive correlation was very weak.

Gyeongsangnam-do has been operating Bravo-taxi, a Gyeongnam-type DRT using taxi vehicles, since 2017 to guarantee the right of mobility for residents who live in areas lacking public transportation. This research investigated and analyzed changes in users' awareness over two years from beginning of Bravo-taxi operation in Gyeongsangnam-do, which started operating Bravo-taxis in 2017, targeting sites lacking public transportation. Through this study, the positive effects of taxi-type DRT were confirmed, such as improving the mobility of residents in areas underprivileged by public transportation, reducing required time for trips, and increasing preference for Bravo-taxis compared to existing buses. On the other hand, problems with the current Bravo-taxi system were also identified. In some areas, it was found that there were not enough coupons for Bravo-taxis, or in the case of Bravo-taxis operating at fixed times, the user's desired time and operating time did not match, resulting in lower satisfaction. The results of this research are expected to be utilized as basic data for service continuity of taxi-type DRT in operation by other local governments.

In the modern society, people can easily reach destination by using the rapidly developed public transportation services. Recently, location information is provided through the network, but this is useless to the weak people on transportation like the handicapped. This paper proposes a bus alert terminal system equipped with the arrival information of public buses based on location information and distance measurement sensor. By using this system, we look forward to providing more convenient and accessible services for the weak people on transportation.

Public transportation card data, which is collected for purposes of the Integrated Public Transportation Fare System, provides neither transfer time nor transfer frequency occurring on the metropolitan city-rail (MCR). And because there are no transfer toll gates installed on the MCR, data on transfers between lines are estimated through means such as elicitations using survey questionnaire, or otherwise through macroscopic observations, which poses the risk of transfer time and frequencies being underestimated. For the accurate estimation thereof, an explanation of the transit path that arises between the Entry-and Exit-Gates must be provided. The purpose of this research is twofold : 1) to build a transit path model to reflect the current state of transfer movements on the basis of transportation card reader data, and 2) to deduce information on transfers occurring in the greater metropolis. To achieve these aims, the idea of Big Nodes is introduced in the model to align transportation card reader operation system characteristics with those of the MCR network. The link-label method is applied in the model as well to make certain that the MCR network runs in an effective manner. Administrative information obtained by the transportation card reader is used to derive transfer time and frequency both in the city's mid-zones, and in the Seoul-Gyeonggi-Incheon district's large-zones. Public transportation card data from a single specific day in year 2014 is employed in the building of the quantified transfer specific data. Extended usage thereof as providing comprehensive data of transfer resistance on the MCR is also examined.

With a land area of 910,768 sq. km, population estimate of 150 million people and GDP-growth rate of 6.9% per annum (2006 est), the centrality of effective public transportation in Nigeria is readily seen. In this regard, rail transportation offers much potential because of its relative safety, reliability, lower cost to the users and being singularly capable of transforming the national economy through mass movement of people, goods and services. Within this context, the demand for an effective railway system, and the enormous potentials for profitable investment in rail infrastructure in Nigeria, is indisputable. Beginning with the history, the paper discusses the main problems of Nigeria's railway transport system; and then makes policy suggestions, after considering the potentials of rebuilding the rail infrastructure. The necessity of this work is premised on the fact that there is a significant gap in critical knowledge about Nigeria's railway transport system.
