Rail-road intermodal freight transport is a transoortation system that rail and road transport are utilized between origins and destinations. The roles of road(truck) in rail-road intermodal freight transport are pick-up and delivery that are keys parts of total transportation process. The objective of this study is to develop and evaluate the pick-up and delivery strategies for container trucks in order to increase their productivity. Two different strategies are developed : One is aimed for minimizing the total traveling distance of container and the other is to reduce the waiting time at client site. The comparative studies are performed on the actual network of Paris metropolitan. The simulation analysis shows that the proposed strategies are quite efficient in various performance measures.

Although motorcycle safety studies to date have identified the causes of motorcycle accidents in general, very few have investigated postal motorcycle accidents by studying the delivery postmen's specific work environment. To better understand postal motorcyclists' driving behavior associated with their delivery workload, we developed a system using V-World platform which visualizes driving behavior in real time along the driver's delivery route throughout an entire work day. We conducted a field test to examine the feasibility of our system by involving six delivery postmen currently working in Songpa, Seocheongju, and Gangseo, respectively. To show the potential of our system for nationwide comparison of postal motorcyclists' driving behavior and their workloads, we present several sample analyses using the collected field data. Although ideally, postmen's workloads should be standardized nationwide, we found large variation depending on regional characteristics of work area which affects postmen's driving behavior.

We provide trends on postal vehicles owned and operated by 10 overseas postal agencies, USPS, Postes Canada, Royal Mail, La Poste, Deutsche Post DHL, PostNL, Australia Post, China Post, Japan Post, and Thailand Post. This will be a useful asset to look into how the posts worldwide operate and manages their postal vehicles and service strategies. In this study, we provide the simple specifications of vehicles operated by each post, how to replace vehicles, how to service maintenance and repair, and modes of pick-up & delivery to be introduced soon. We expect this study to present appropriate policy implications for both postal agencies and logistics companies that are facing a major turning point in logistics to operate and evolve the delivery vehicles.

우리나라의 우편 집배국에서는 우편배달업무의 효율성 제고를 위해서 자동 순로구분기를 개발하여 도입 운영하려는 프로젝트를 진행 중이다. 그러나 새롭게 도입하는 자동화시스템이므로 순로구분 업무프로세스의 표준모델의 개발이 절실히 요구되고 있다. 본 연구에서는 시범적으로 순로구분기를 도입 운영하고 있는 집배국을 대상으로 순로구분업무를 분석하고 그를 바탕으로 자동순로구분 업무프로세스의 표준모델을 제시한다.

Currently the amount of general letter mail in Korea is on an increasing trend; especially it shows the seasonality that is concentrated in the end of the month or the year. However, the situation is not treated appropriately Moreover. manpower insufficiency if the carriers causes the poor service and the heavy burden of work. Under the existing conditions, the various efforts such as development of the automatic sequence sorting system and construction of the address database are given in order to quicken mall process and lighten the carriers' burden But the inconsistent addressing and the various expressions of address drop the systems and the carriers off in efficiency. In this study, we present the Korean postal addressing standards to make it possible to improve the performance of address recognition and help postmen to sort the mail; particularly focusing on the substance. After analyzing the domestic system, the information structure and the problems of postal address, we propose four fundamentals and the standards including synonyms and acronyms. In addition, we suggest several considerations for mail format. We expect that this study could support the postal service in Korea as a basic standard.

본 논문에서는 도로명과 건물 번호에 기초한 새주소 체계를 우편 물류 환경에 도입하므로 발생되는 문제점과 영향 요소를 기술하며 각각의 영향 요소에 대한 구체적인 대응을 모색한다. 새주소 체계는 우편물의 접수 및 구분 및 배달 과정에서 모두 영향을 주며 현재의 정보 시스템이나 우편물 구분 장치에도 직.간접을 영향을 주어 단기적으로는 새로운 주소 체계를 관리하는 우편 주소 관리 시스템 도입이 요구되고, 아울러 기존의 지번 주소와 새주소의 매칭 테이블 구축 및 집배구 수작업 구분 환경 개선 등이 요구되며, 중.장기적으로는 새주소 DB 구축을 통한 우편물 구분 장치의 새주소 인식 기능 개선 및 새주소 체계에 적하한 우편번호 및 집배구 체계 도입이 필요하다.

분립체외 혼상류로서이든 캡슐수송이든 파이프수송은 수송요원이 거의 불요하다는 점에서도 각광 을 받는다. 공장내에서의 수송뿐만 아니라 도시폐기물을 직접 파이프에 투입하여 공기수송 한다 거나 큰 삘딩내에서 서류를 파이프 공기수송하는 것 등은 이미 선진국에서 널리 사용되고 있거니 와 가장 신속정확을 요하는 우편물의 집배도 포스트와 우체국과의 사이에 파이프 수송이 가능할 것이며 문화사회의 각방면에도 그 적성은 광범위하여 파이프 수송은 바야흐로 내일의 수송의 주 주역이 될 것으로 기대된다.
