A Study on the Relationship between Traffic Accident Rates and Geometric Characteristics of the Expressway in Korea
Journal of Korean Society of Transportation, volume 3, issue 1, 1985, Pages 3~21
Since the expressway was first opened in 1968 there has been continued demand for constructing new lines of expressway, and thus it amounts to 1,420.5km in total length as of 1984. As the expressway becomes to take up more important role in our country facing motorization traffic accidents have become more of social issues, although its accident rates are relatively low compared to those on general highways in Korea, which is among the highest in the world. The purpose of the study is to investigate the correlation between the traffic accident rates on the expressway and their geometric characteristics based upon 1982 data. In order to extract the correlationship among them on as much disaggregate basis, the study has carried out the analysis on the primary data aggregated on the 100 meter intervals. One of the important findings was, among others, the design criteria of the expressway should be reconsidered with respect to the radius of the curve, superelevation, climbing lane, composed gradients, interchange facilities, tunnels and so on.
Systems Approach to the Transportation Administration System in Korea -With Emphasis on Inter-Organizational Information Flow Analysis-
Journal of Korean Society of Transportation, volume 3, issue 1, 1985, Pages 22~45
Most transportation problems are expected to be dealt with by public sector, mainly government organizations, even though few articles are available to tackle the problems from the administrative points of view. This study has the following scopes: to define the transportation system; to derive the subsystems, i.e., the functions of the system; to identify the elements (or organizations) of performing the functions; to study the inter-organizational relationships among the elements and to derive problem areas; and finally to propose a new administrative system for solving the problems. System Theory was exclusively used for defining the system and deriving subsystems of transportation. Laws and regulations about government organizations were analyzed to identify the relevant organizations. Communications analysis was used for deriving the relationships among the organizations. Ledger books containing incoming-and-outgoing documents in the sampled organizations were inputed onto computer. Exactly 49,367 records(i.e., information flows) were stored for this analysis. Finally, this study proposed a new administrative system that is expected to result in more cooperative and productive inter-organizational relationships among the transportation organizations.
Derivation of Optimum Time and Distance Taxi Fare Structure Based on Social Costs
Journal of Korean Society of Transportation, volume 3, issue 1, 1985, Pages 46~57
The objective of this paper is to derive a optimum distance and time taxi fare structure based on social costs. Social costs expressed in terms of congestion and vehicle operating costs were successfully internalized. Speed and volume data for three major arterials in Seoul CBD were used. Optimum congestion charge turned out to be 97.01 Won/Km which can be regarded as congestion tax in the context of Seoul CBD. This congestion tax can possibly be incorporated into time-based taxi fare structure. Congestion is likely to be reduced as a result of imposition of time-based taxi fare which reflects social costs.
A Study on Pooling of the Road Freight Transport Information System
Journal of Korean Society of Transportation, volume 3, issue 1, 1985, Pages 58~75
On facing the information society, the multi-faceted information utilization and the establishment of synthetic information management system in the overall industry and business administration have raised considerable attention. Thus, this study aims at the improvement of freight transport management through the establishment of pooling of the road freight transport information system as its effective information supporting system. Especially, it describes the freight transport information network, structure, function, and subject of the freight transport information center, as a basic planning design for the freight transport information system. Furthermore, it deals with the identification of the systems design requirements, working process, and S/W & H/W design specifications. Finally, we expect that this study will be contributed for the improvement of the road freight transport business to meet both the increase of freight transport demands due to the continuing economic growth and the social needs for the establishment of transport-order
Regional Differentiation Effect of Transportation System
Journal of Korean Society of Transportation, volume 3, issue 1, 1985, Pages 76~85
The significant role of transportation system for economic development process has been recognized, but the argument that transportation improvements stimulate economic development has brought sometimes no resonance in lacking of a plausible theory on the conditions and process of economic development by transportation investment. This paper reviews the theory on regional differentiation of transportation system and shows why and how the installation of a new transportation system or the improvements of the old transportation quality differentiate the spatial order of economic activities. It presents the interaction between the change of transportation quality with introducing of definition "transportation value" as tool of its determination and economic activities following the regional differentiation process, which result means regional defferentiation of niveau of economic development.
