Integrated logistics information system in Korea

The transport infrastructure will provide the necessary capacity for freight movement and handling. However, the increase in the physical infrastructure alone is not a sufficient condition for the improvement of logistics systems. The logistics information capability which facilitates the seamless flow of information is a very important element in further enhancing the efficiency of logistics activities and in potentially reducing the demand for the transport infrastructure itself. Reviews the existing logistics information practices in Korea and describes recent nation‐wide efforts to build an integrated logistics information system (ILIS). Raises some important issues for successful implementation of the system and also discusses the relationship between the Korean CVO (K.CVO) programs.

Empirical Case Study of Spatial-Temporal Student Activity Population

The spatial–temporal activity–presence approach is used to estimate and validate hourly activity populations for individual buildings. A case study modeled the spatial–temporal activity of students at North Carolina State University. For the validation of results, student registration records provide observations of class schedules and locations for dynamic, time-varying class or study activity populations at individual buildings. Results show that the spatial–temporal activity–presence approach provides reliable estimates. This empirical case study should improve acceptance of the spatial–temporal activity procedure for activity distribution and demonstrate its value for other planning applications.

New Approach to Appraisal of Rail Freight Projects in South Korea: Using the Value of Freight Transit Time Savings

This paper contributes to the estimation of the value of rail freight transit time savings, reliability, and service frequency for producers and transport operators by using stated preference data for short-haul rail freight shipments in South Korea. To appraise investments in freight projects in South Korea, the mixed logit model was used to determine the value of rail freight transit time savings, resulting in an estimated savings of about

The results for freight time value for different economic agents are surprising: shippers perceived the value of transit time, transit time reliability, and service frequency to be far higher than producers did. Shippers valued rail freight transit time savings at about

Development of a bicycle level of service model from the user’s perspective

This paper introduces recent technological trends in Dedicated Short Range Communications (DSRC) applications for ITS and an economic evaluation, focusing on the City Bus Information System (CBIS) and Electronic Toll Collection System (ETC) in Korea. From a research perspective, it is necessary for the seamless development and maintenance of technical and competitive edges, and the proper budgetary allocation for research and development. In addition, the progressive participation of private companies having the leading technologies on active DSRC is also required.

Development of Bicycle Level of Service Model from the User's Perspective Using Ordered Probit Model

In recent years, congestion pricing has gained popularity as a method for managing peak period congestion on major roads in urban areas. Especially, Intelligent Transportation Systems (ITS) technology has resulted in an electronic toll collection (ETC) system called “Hi-Pass” which is operated by the Korea Highway Corporation as a pilot program. Limited sections of highway have gained a good approval rating from motorists. In this research, the Korean highway toll system was analyzed with respect to the brief legal history of the toll road, collection method and levels. In addition, the electronic toll collection policy for foreign countries including France, Norway, and Italy are investigated. The toll system of each country is clearly differentiated with regard to the institution, regulation and the economy. After reviewing the pilot ETC program in Korea, the “Hi-Pass” system, several important factors were found. First, a more concrete marketing strategy for ETC users will be needed to encourage continued usage. Especially, frequent users and higher income users have more easily adopted the ETC system than others did. Second, in order to encourage the non-user to the ETC system, the costs of on-board units need to be reasonably low (about
