Recently, Logistics industry has emerged a new u-logistics paradigm combines USN / RFID technology. In this paper offers a vehicle history Web-based logistics management system based on the u-logistics paradigm. The design of this system is considered all events processes as a form of recycling and entire system is to modeling based UML of object oriented. Also It was undergone some process to make sure by logistics vehicles identified that RFID based was identified vehicle logistics. To identify logistics vehicle based RFID, identified the logistics vehicles is a process that will determine. The implementation method designed the interface based web which uses in the manager to C/S methods, consideration of the mobility of the system user implements the user GUI based PDA. As well as, In this paper was separated customer, manufacturer, distributor, administrator, drivers, respectively and focuses to raise a system reusability which is implementation by separately for each feature.

This article is concerned with the technology to provide car driver the car's status which are composed of car trouble code in car engine and many sensors. In addition, it installs vehicle diagnostic programs on wireless communication's portable device, for example, Smart phone, PDA, PMP, UMPC. As a result, this is to provide car manager with many information of car sensors when we go to car maintenance. it can monitor relevant information on vehicle by portable device in real time, alert drivers with specific messages and also enable them to address abnormalities immediately. Moreover, the technology could help the drivers who perhaps don't know very well about their vehicles to drive safely and economically as well; the reason is because the whole system is composed of just Vehicle-information collecting device and personal wireless communication's portables and transfers the relating data to server computers through wireless network in order to handle information on vehicles. This technology make us monitor vehicle's running, failure and disorder by using wireless communication's portable device. Finally, this study system is composed of a lot of application to display us the car's status which get car's inner sensor information while driving a car.

As the ubiquitous environment is created, the latest ports introduce U-Port services in managing ports generally and embody container's location identification system, port terminal management system, and advanced information exchange system etc. In particular, the location identification system for freight cars and containers provide in real time the information on the location and condition for them, and enables them to cope with an efficient vehicle operation management and its related problems immediately. However, such a system is insufficient in effectively handling with the troubles in a large-scale port including freight car's disorderly driving, parking, stop, theft, damage, accident, trespassing and controlling. In order to solve these problems, this study structures the vehicle positioning system and the image verification system unsing high resolution image compression and AVE/H.264 store and transmission technology, able to mark and identify the vehicle location on the digital map while a freight car has stayed in a port since the entry of an automatic gate, or able to identify the place of accident through image remotely.

급격한 차량 수요의 증가로 인한 주차공간의 부족으로 인력기반 주차관리의 한계점을 이용한 여러 위법 행위가 발생함에 따라 관리자의 정기적인 순찰 및 관리의 필요성이 증가하고 있다. 기존 인력기반 주차관리 시스템은 관리자에게 전적으로 의존하고 있어 관리의 정확도 및 효율성이 비교적 낮다. 본 논문에서는 엣지 컴퓨팅 기반의 클라우드 주차관리 시스템을 제안하며, 이는 효율적인 주차관리를 통한 시간과 노동력 절감에 기여한다. 본 시스템이 제공하는 주요 기능은 다음과 같다. 1) 주차구역 및 주차 차량 정보를 분석하여 입·출차를 관리하고 관리자에게 실시간 주차 현황 정보를 제공한다. 2) 추출된 차량 정보를 바탕으로 부정주차 여부를 감지하여 지정주차 구역 관리를 자동화한다. 3) 관리자에게 시간대별 주차구역 점유율 정보를 제공하여 거주자의 가용 주차공간을 확보한다. 4) 거주자의 선호 주차구역 및 시간대를 파악하여 거주자의 주차 편의성을 제공한다. 위 기능을 통해 기존 주차관리의 비효율성을 개선하고자 한다.

The vehicle has many technique change from The requirement of the safety the energy environment and convenience dimension is an enlargement toe. This is keeping changing the paradigm of the vehicle industry rapidly. The change to be technical such brought the intelligence of the former control device. And this organizes a sensor network among each systems and makes new traffic system. This paper a standard framework based on Sensor. We call it Vehicle Management System. The VMS used MOST network and It is able to make the stability of the component swap time or vehicle order the greatest.

차량 검지 시스템은 실시간으로 교통상황 자료를 수집하는 시스템으로, 관리대상 구간의 자료를 수집하여 시시각각 변하는 교통상황에 대한 효과적인 교통관리를 수행하도록 한다. 현재 차량 검지 시스템은 상당한 안정성과 정확성을 확보 하고 있기는 하나, 시스템 구성시 검지 시스템 자체의 구성에 드는 비용과 시간 보다는 센터와의 통신에 필요한 시스템 구축이나 전원 확보를 위한 전원선 공사등과 같은 주변 환경 요건 구축에 더욱 많은 비용과 시간이 드는 문제점이 있다. 이는 정보수집의 방식이 현재까지는 센터와 1:1 연결을 통한 정보교환에 의한 것이어서 전국단위의 N개 총신회선의 정보교환을 위해서는 1:N개의 통신회선이 필요하기 때문이다. 따라서 본 논문에서는 이러한 문제점 해결을 위한 레이더 차량 검지 시스템용 통합 프로토콜 제어기의 개발을 수행한다.

It becomes easy and generalized to track the cellular phone users and vehicles according to the Progress of wireless telecommunication, the spread of network, and the miniaturization of terminal devices. It has been constantly studied to provide location based services to furnish suitable services depending on the positions of customers. Various vehicle tracking and management systems are developed to utilize and manage the vehicle locations to relieve the congestion of traffic and to smooth transportation. However the designed previous work can not evaluated in real world, because most of previous work is only designed not implemented and it is developed for simple model to handle a point, a line, a polygon object. Therefore, we design a moving object query language and implement a vehicle management system to search the positions and trajectories of vehicles and to analyze the cost of transportation effectively. The designed query language based on a SQL can be utilized to get the trajectories between two specific places, the departure time, the arrival time of vehicles, and the predicted uncertainty positions, etc. In addition, the proposed moving object query language for managing transportation vehicles is useful to analyze the cost of trajectories in a variety of moving object management system containing transportation.

This paper presents implementation details of car communications system based on V2I2V model over broadband wireless networks including WCDMA, HSDPA and WiBro. Also, we measures the major performance metrics such as Round Trip Time, end-to-end latency and others between in-vehicle client and location management system by driving across urban areas in Daegu city. Analysis of experimental results would be helpful to consider the applicability of traffic safety services using V2I2V-based car communications over various broadband wireless networks.
