As a way to allocate lots of orders to many participants for vehicle allocation problem, this study has used an agent negotiation based reverse auction model. This agent negotiation provides coordination functions allowing all participants to make a profit, and accomplishing Pareto optimum solution from the viewpoint of a whole trucking cargo transportation network. In order to build a strategic cooperation relationship based on information sharing, this agent negotiation provides a coordination mechanism in which all the participants including consignors, brokerage firms, and car owners are able to attain their own profits, and also that ensure a competitive market. This study has tried to prove that the result of an agent-based negotiation is the Pareto optimal solution under the present market environment. We established a mathematical formulation for a comparison with the Integer Programming model, and analysing e-Marketplace, structure of shipping expenses and brokerage system in the trucking cargo transportation industry.

Ensuring the safe arrival of delivery cargo at its intended destination is of utmost importance. Truck drivers play a crucial role in guaranteeing the secure delivery of cargo without any mishaps. However, there are various factors that may lead to delayed arrival of trucks at their destination, such as late departures or prolonged loading operations. The timely departure of cargo transportation is contingent upon several variables, including the driver's experience, cargo volume, and loading time. If the transportation commencement is delayed, it may increase the risk of accidents due to an elevated operating speed. Consequently, we conducted a study to investigate the correlation between cargo loading time, cargo volume, driving experience, and the likelihood of accidents. Our findings indicate that both cargo volume and driver experience can impact the likelihood of vehicle accidents. Furthermore, all factors can have an interactive effect on the occurrence of accidents. However, extending the loading time may mitigate the impact on the likelihood of accidents.

Recently, the number of consumers using digital online distribution platforms is increasing. This caused the rapid growth of the e-commerce market and increased delivery volume in urban areas. The logistics system, designed ar006Fund the city center to handle the delivery volume, operates a delivery system from the outskirts of the city to the urban area using cargo trucks. This maintains an ecosystem of high-cost and inefficient structures that increase social costs such as road traffic congestion and environmental problems. To solve this problem, research is being conducted worldwide to establish a high-efficiency urban joint logistics system using urban railway facilities and underground space infrastructure existing in existing cities. The joint logistics system begins with linking unmanned delivery automation services that link terminal delivery such as cargo classification and stacking, infrastructure construction that performs cargo transfer function by separating from passengers such as using cargo platform. To this end, it is necessary to apply the device to the vertical and horizontal transportation machine supporting the vertical transfer in the flat space of the joint logistics terminal, which is the base technology for transporting cargo using the transfer robot to the destination designated as a freight-only urban railway vehicle. Therefore, this paper aims to derive holistic viewpoints needs for design requirements for vertical and vertical transportation machines and freight transportation standard containers, which are underground railway logistics transport devices to be constructed by urban logistics ecosystem changes.

Most cargo truck drivers of small and medium-sized firms often process their works using a paper document containing the transport-related information. However, these paper documents that are used to plan route or check the list for cargo loading have the potential to be lost or damaged. Also, it is not easy to manage cargo using certain devices not the paper document in case of small and medium-sized firms because the budget is limited. In this paper, we implement the cargo transportation system for desktop and android-based application in order to solve these problems. A manager for cargo transportation is provided a simple interface to manage the transport-related information through the desktop application. A cargo truck driver is provided functions such as plan route and make a call to manage the transport-related information through the android-based application. This system is implemented to improve the efficiency of cargo transportation.

This paper considers the problem of determining the cargo flow and the transportation mode in each trade route while satisfying the demand. Especially, the problem incorporates short sea shipping in Korea, which is becoming more important in order to improve efficiency of Logistics. The objective is to minimize the sum of shipping and inland transportation costs. To solve optimally the problem, this paper employs a linear programming model, which is an operations research technique for optimization. The problem is formulated by extending the well-known network design problem by considering capacity at seaport and limitation of total number of vehicles. The model is solved using CPLEX, a commercial linear program software. The test results using a real cargo flow data in Korea show that the model represents closely the real situation.

Coastal cargo shipping is regarded as environmentally friendly and less costly compared to other transport modes: therefore, many developed countries endeavor to activate coastal cargo shipping. In Korea, a couple of policies are suggested for coastal cargo shipping; however, shippers' aspects seem to be neglected or not analyzed. In this regard, this study aims to identify barriers in the coastal cargo shipping, in respect to shippers' aspects. To find out the reasons shippers hesitate to use coastal cargo shipping, we made a questionnaire and surveyed. We found out some meaningful points in this study as the followings. First, the proportion of using the coastal cargo shipping is very low. Second, the shippers give weights on time and costs factor, and their preference for punctuality and stability of the transportation services is extremely high. Third, the shippers believe that improvement of the services of the coastal cargo shipping is very important in national logistics system although most do not use currently. They also believe that the success of coastal cargo shipping lies in whether it can transport the huge amount of cargos with lowest costs. Finally, the most important factor, when they choose the transport mode, is the punctuality and stability of the transportation services.

Dangerous cargo in maritime transportation is increasing in international trade. The types and forms of dangerous cargo are very diverse, complex, and the scope is expanding widely. For this reason, it is increase risk of accident threatens the safety of ships and other cargoes, as well as serious damage. Carriers' require special care and handling of dangerous cargo and have a duty of care for safe transport. The shipper is obliged to notify the carrier of the nature and characteristics of the dangerous cargo prior to loading on the ship, the responsibility of the carrier varies depending on the notification or not. This study compares and analyzes the concept and classification of dangerous cargoes, the provisions of the Hague rules, Hamburg Rules and Rotterdam Rules about Carriers' Dangerous Cargo Liability Regulations, after reviewing case studies. We intend to provide information to dangerous cargo handling, the carrier.

The Port of Pusan, the largest port in Korea, handled 23% of total sea borne cargo movement, 14% of imported cargo, 58% of exported cargo and 95% of container cargo in 1989. Also the port of Pusan has been played a key role in handing container cargo throughout the last 10 years. The paper is aimed to survey the effect of sea borne cargo movement to urban transportation, that is, to find traffic volume arising by general/bulk cargoes through the port and to estimate vehicle rated of container tractor tailer on the roads between terminal including conventional piers and ODCY, and finally the following results are obtained. (1) AADV of truck to transport general/bulk cargoes are 6,322 units in 1989,and routes penetrate into the center of city and pass through the most of urban arterials. (2) In the container transport, if HVEF is adopted to 3 of tractor trailer, AVR in each transport freeway 13.7%. (3) IF HVEF is adopted to 6 of tractor trailer. AVR are as follows: BooDoo-Ro 44.1%, WooAm-Ro 39.3%, SooYoung-Ro 17.8%, Urban freeway 20.3%. Based upon these results, the following suggestions were drawn : o ODCY scattered around the city should be unified in a few groups to raise port productivity. o Rail service for inland container transportation should be escalated to relieve urban traffic congestion. o Coastal feeder service between terminal and hinterland should be studied to restrict the penetration of container tractor trailer into the central parts in the urban areas. o Exclusive freeway system for effective container transportation should be implemented to reduce urban traffic delay.

Recently, in order to improve the efficiency of freight transportation on existing lines, a new freight train model is needed to develop urgently. The weight balance of the cargo for the freight vehicle is very important for the stability of the running train and the safe transportation of the cargo. For achieving the cargo weight balance, we proposed a Cargo Balancing Control(CBC) system on the Freight vehicle equipped in between under frame of car body and bogie system. The Cargo Safety Monitoring(CSM) system was designed to supervise status of the Cargo on freight train. The monitoring system can display real time status data from sensors and various signals effectively. We suggested that this paper is a very useful approach for keeping the safety of running freight trains on existing lines.
