Generally, the tons lifted and ton-kilometers are widely used to analyze the road freight transport. However, these two indicators are simply to show the road freight transport statistics rather than to explain the road freight transportation systems. In this study, the variables such as the number of distribution channel levels, the integral distance, tons in transport and the average transport distance are defined and estimated to investigate the road freight transport system of Korea. In order to compare the road transport system of Korea to other countries, the comparative study was conducted including USA, Japan, Holland and Taiwan. The major findings of this study are as follows; i) The number of distribution channel levels and integral distance of Korea and Taiwan have been increased, but the average transport distance decreased from 1971 to 1996 period. ii) On the contrary to Korea case, the number of distribution channel levels and integral distance of US, Japan and Holland have been decreased, but the average transport distance increased. iii) In the time-series model analysis shows that the number of distribution channel levels are statistically positively closely related to the logistics costs and the costs of transportation as a percentage of GDP.

This research aims to examine the influence of road transportation infrastructure on the mobility of goods transport and the regional economy in Langkat Regency in Indonesia. This type of research is an associative and explanatory research whose data is obtained through a questionnaire survey. This study took a sample of 305 respondents using probability sampling in Langkat Regency, North Sumatera, Indonesia. Data analysis techniques use path analysis. The research results showed that the road transportation infrastructure variables had a significant and positive effect on the mobility of goods transport. Road transportation infrastructure and freight mobility simultaneously have a significant and positive effect on the economy of Langkat Regency. Road transportation infrastructure with the dimensions of road accessibility and maintenance partially directly has a significant and positive effect on the economy of the Langkat Regency. Road transportation infrastructure with the dimensions of road design and road construction quality partially does not have a direct effect on the regional economy, but has a positive and significant effect through the mobility of freight transport. The mobility of goods transport becomes an intervening variable that acts to mediate or determine the relationship between road transportation infrastructure variables to the regional economy.

In Korea, previously implemented road construction project caused a big budget waste due to overestimation of transport demand. There could be reasons for such inaccuracy of transport demand estimation, but the main reasons are: (1) low reliability of used basic road transport data and (2) inadequate sharing of data among agencies/departments. The National Transport Database and the Household Travel Database in Seoul Metropolitan Area, two representing basic road transport database, will be used to the establishment of a road construction plan that will be promoted afterwards. However, these materials have problems such as low reliability and inadequateness, too. Hence, focusing on transport demand estimation related databases, this paper will make proposals for enhancing their reliability and data sharing.

Road freight transport industry in Korea contains many and complicate problems such as over supply of the vehicle caused by rapid policy changes, illegal multilevel transactions, poor truck drivers working environment, lack of road freight transport related statistics and so on. Korean government has developed various logistics industrial policy trying to solve these problems in various ways. However, the relationship among the problems and action plans has been more and more entangled since the part of suggested policies have made another perverted problems. These complex structure of the toad freight transport industry in Korea makes difficult to identify and to solve the problems. Causal map method helps to give a clean picture to understand the complex industry at a glance. This study contributes for visualization of the causal relationships among the existing problems and related policy issues in the road freight transport industry in Korea by causal map. This study could be helpful to develop the actual road freight transport industrial policies including the illogical multilevel and unfair transaction in Korea.

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.

We have the common aim of encouraging freight to be carried by rail rather than by road because there are sufficient environmental, social and public benefits. Thus it is important to lead to freight traveling by rail rather than road and to ensure that freight on rail does not transfer to road. In Korea, taking freight off road and moving it by rail is more expensive from a point of total transport costs. Hence this paper is focused in the improvement methods for the rail freight transport which could be helped to promote the efficiency associated with moving freight by rail.

The introduction of Connected and Automated(CAD) technology has a growing interests especially in areas with low demand for transport, where often the local transport services do not connect to peripheral areas for more efficient and convenient mobility services. However, there are few researches on CAD-based mobility services in areas with low demand for transport. Because current researches are mainly focuses on introduction of CAD-based mobility services in area with high demand for transport such as urban and highway. These two areas have different road environments and these differences require different driving technology especially related to Operational Design Domain(ODD). ODD is important factors for introduction of CAD-based mobility services. Therefore, we compare the road environments of areas with low demand for transport and areas with high demand for transport in terms of ODD. In addition, this paper proposes suggest guidance for the introduction of CAD-based mobility services in areas with low demand for transport such as rural and suburban areas.

As the portable traffic information collection system using probe vehicles spreads, it is becoming possible to collect road hazard information such as portholes, falling objects, and road surface freezing using in-vehicle sensors in addition to existing traffic information. In this study, we developed a integration and decision algorithm that integrates time and space in real time when multiple probe vehicles detect events such as road hazard information based on GPS coordinates. The core function of the algorithm is to determine whether the road hazard information generated at a specific point is the same point from the result of detecting multiple GPS probes with different GPS coordinates, Generating the data, (3) continuously determining whether the generated event data is valid, and (4) ending the event when the road hazard situation ends. For this purpose, the road risk information collected by the probe vehicle was processed in real time to achieve the conditional probability, and the validity of the event was verified by continuously updating the road risk information collected by the probe vehicle. It is considered that the developed hybrid processing algorithm can be applied to probe-based traffic information collection and event information processing such as C-ITS and autonomous driving car in the future.

This paper proposed the framework for the Korean transport accounts which is suitable to Korean situation and can be used for international comparison. The framework is composed of the costs, the revenues and the estimation methodology. This framework is applied to both the Korean road and rail transport, respectively. The result showed that the total cost compared to GDP for the road was higher than the Europe's by 3.23% and that for the rail was lower than the Europe's by 0.67%. Also, the result showed that, in terms of the unit cost, the passenger cost per person-kilometer of road transport was 4.8 times higher than that of rail transport and the freight cost per ton-kilometer of road transport was 2.4 times higher than that of rail transport.
