기업에서 발생하는 물류비용 중에 운송비가 차지하는 비중은 50% 이상이다. 국제 유가 급등에 따른 운송비용이 급상승하면서 배송관리의 중요성은 더욱 커지고 있다. 배송관리시스템은 고객에게 주문받은 물품을 물류센터에서 배송계획을 수립하여 배차지시, 정산관리 및 차량의 트랙킹 등 전반적인 배송과정을 관리하는 시스템이다. 기존의 배송방법은 우편번호를 기준으로 하는 고정 라우팅 방식을 사용하였다. 이러한 방식은 배송기사가 비교적 쉽게 배송할 수는 있지만 물동량의 급격하게 변할 때에는 실시간으로 대응하지 못하는 문제점을 갖는다. 본 논문에서는 물동량의 변화에 효율적으로 대응하여 배송하기 위한 방안으로 지능형 배송관리시스템의 설계 방안을 제안한다.

The major goal of this research is to develop an optimal route search algorithm for an intelligent route guidance system, one sub-area of ITS. ITS stands for intelligent Transportation System. ITS offers a fundamental solution to various issues concerning transportation and it will eventually help comfortable and swift moves of drivers by receiving and transmitting information on humans, roads and automobiles. Genetic algorithm, and fuzzy logic are utilized in order to implement the proposed algorithm. Using genetic algorithm, the proposed algorithm searches shortest routes in terms of travel time in consideration of stochastic traffic volume, diverse turn constraints, etc. Then using fuzzy logic, it selects driver-preference optimal route among the candidate routes searched by GA, taking into account various driver's preferences such as difficulty degree of driving and surrounding scenery of road, etc. In order to evaluate this algorithm, a virtual road-traffic network DB with various road attributes is simulated, where the suggested algorithm promptly produces the best route for a driver with reference to his or her preferences.

This paper presents a method of effective smart streetlight I the express way. The proposed method support the driver's safety system which informed the before ahead accident besides basic lighting function. Also, the proposed system will be able to apply to the ITS(Intelligent Traffic System) for the future.

Because of development of information communication and multimedia technology, the focus of M2M(Machine to Machine) intelligent network, multimedia collaboration environment, and transportation safety service is increased. This paper describes a multimedia replicated architecture based on Shepherd environment for transportation safety service. The relationship of information collection and utility is relationship of man to man, but is developed object to object by information communication and control system. This paper suggests a design of multimedia cyber collaboration environment based on M2M. This structure can make multimedia collaboration environment and fault tolerance, so on easily. Because M2M system does not affected to all system in spite of occurring to fault to a node or resource, it has a good condition for design of transportation safety service running on M2M.

In this paper which it is relating to the DSRC system based road side equipment, we propose the protocol stack architecture of road side equipment and the process structure of the main RM, L7 and LLC layers which is road side equipment device as well. And also we design the signal flow and data-transfer process as well between road side equipment and on board equipment to describe the installation process between road side equipment and von board equipment based on DSRC system. Thus, it is possible to provide various application services between intelligent transportation systems of road side equipment and local server, as well as it enables the local server managing the memorys of on board equipment which entry in service area thru the road side equipment.
