Abstract In metropolitan region, one of the most serious factor to accelerate traffic congestion is caused by radical increasement of private car that transport efficiency is relatively low. So, in order to relieve this traffic congestion, it must be provided that the policy which has priority to hold back for the private car demand that mainly is focused to the public transportation system. The main purpose of exclusive bus lane is making travel speed of bus more higher, improving regularity of bus operation in order to provide a better passenger service and increasing the attractiveness of the bus service relative to private car use.The purpose of this study is to minimize the congestion and maximize passenger service of public transportation system in Pusan by determining new criterion of exclusive bus lane and proposing how to improve operation technique of it.

유비쿼터스 컴퓨팅을 실현하기 위한 기술인 RFID와 USN은 기술적 유사성과 상호 영향에도 불구하고 별개의 연구로 인식되어 RFID와 USN의 기술적인 융합에 대한 연구는 미미하다. 이에 본 논문에서는 USN과 RFID의 융합뿐만 아니라 비용과 확장성 면에서의 효율성을 제공하기 위하여 USN의 환경의 다양한 센서 데이터를 RFID 미들웨어서 처리할 수 있는 방법을 제안한다. 특히 RFID 미들웨어 내부에서 처리할 수 있도록 다양한 유형의 센서 데이터를 EPC 데이터 포맷으로 변환하는 방법을 제안함으로써 RFID 미들웨어에서 센서 데이터를 효율적으로 처리할 수 있다. 본 방법을 이용하면 국제 표준 스펙에 기반한 RFID 미들웨어가 RFID 태그뿐만 아니라 일반 센서 데이터를 효율적으로 처리할 수 있기 때문에 사물의 인식정보와 센서 데이터를 활용한 다양한 유비쿼터스 응용 서비스를 저비용으로 구현할 수 있다. USN and RFID, as new technologies for realization of ubiquitous computing, are closely related with each other technically. Nevertheless, these technologies are recognized as a separate research topic, and there are few researches on technical convergence of the two research areas. In this paper, we propose an efficient processing method of various kinds of sensor data which are used in USN environment to provide efficiency from the view point of not only convergence of USN and RFID technologies but also cost and extensibility. Especially, we propose a method of conversion of various sensor data into EPC data format which can be handled in a RFID middleware. Using the proposed method, RFID middleware systems based on international standard specification can handle not only RFID tag data but also general sensor data efficiently, and various types of ubiquitous application services can be implemented at low cost and in a short time.
