  • This study is to review the road traffics and its process by the type of business in annual Statistical Yearbook of Transportation published under the supervision of Ministry of Transport, and the main purpose of this study is to find out an recommendations for the result of the review. For this purpose, this study surveyed and analyzed actual results and its output process in Statistical Yearbook by vehicle and business types. The local survey is performed for the nationwide 23 cities to produce passenger (ton) number and passenger (ton)-㎞ number by vehicle and business types. The result of the local survey is compared with the road traffics in Statistical Yearbook of Transpotation. The result of the survey analysis reveals that road traffic in Statistical Yearbook is produced formally and there is remarkable differences between road traffic in Statistical Yearbook and local survey output. Conclusively, statistical output process of road traffics must be improved to solve th se problems mentioned above in respect to system and technic. Also it is recommended to publish its own road traffic statistics (tentatively named Statistical Yearbook of Road Transportation) just like Statistical Yearbook of Railroad for user's expediency and practicality.

  • Two experiment are planed to identify driver's safe driving behaviour by curve radius, road surface condition in curve section. At four-lane and two-lane road, conducted experiments are check on driver's feeling of safety that 30 subjects do not feel discomfort. And using the data from these experiments, this study compare physical speed (not slipping, fall our of the road) with safety driving speed(drivers felt a comfortable and safe speed) each curve radius and fiver road surface condition(drying, wet, rain, snow and ice). As a result, safe driving behaviour factors that are derived to curve radius of 100m units, five road surface conditions enable to represent quantitative analysis of driver's discomfort. This study will develop road design method and evaluation reflected ergonomic aspects.

  • ETC가 보급되면 다양한 요금을 설정할 수 있다. 요금의 다양화는 이론적으로 다른 운전자에게 다른 요금을 부과한다는 차별요금을 의미한다. 차별요금은 그 이름과는 달리 잘 설정한다면 이용자인 운전자에게나 유료도로 운영자 모두에게 이익을 주는 것이다. 요금다양화를 잘 이용하기 위해서는 유료도로 운영자에 대한인센티브 부여가 중요하고, 여기에 주력 할 필요가 있다.

  • 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.

  • In general, the rail transportation recognized as a better transportation mode than road transportation in terms of the environment. However, due to a lack of quantitative analysis based on Korean data, foreign cases for environmental advantages of the railway have often been cited in Korea. To address this issue, we estimated the energy consumption of passenger and freight transportation using certified activity data from Korea Railroad Statistics and the Electrical Work Report for railway and the Energy Consumption Survey for road. We estimated the Green House Gas emission of passenger and freight transportation on a Tier 1 level by applying the IPCC 2006 Guideline. Finally, we calculated the energy consumption unit and GHG emission unit to determine the environmental impact of rail and road transportation. We also compared the analyzed results of high-speed rail and auto as typical means of rail and road transportation.
