This paper estimates relationships between the supply of national highways, measured in lane-km, and the quantity of traffic, measured in vehicle-km traveled. The analysis uses a panel data set of annual observations for the years 1984 to 2003. By using a log-linear lag effect model designed to capture short and long term effects, the paper estimates that national highway vehicle-km traveled has a lane-km elasticity of 0.268 at the country level (Non-Seoul Metropolitan area) and 0.41 at the Seoul metropolitan area for the short term. For the long term, the paper estimates 0.8 for the country level and 1.23 for the Seoul metropolitan area. This paper finds conclusive evidence that increases in highway lane-miles have generated traffic over the period of study, however the increasing ratio of the generated traffic decreases gradually, particularly during the late 1980s.

서울시는 선진 대도시와는 달리 노면교통이 도시고속도로 중심이 아니라 신호교차로와 좌회전이 많은 일반 간선도로에 대한 의존도가 높기 때문에 일부 구간에서의 정체는 공간적으로 파급효과가 크게 나타나는 도로교통체계를 갖고 있다. 따라서 통행량 유발이 집중되는 시설이 많이 위치한 강남과 도심의 일부구역의 정체는 강남과 도심 전체의 교통소통에 악영향을 주고 있고 이러한 문제를 해소하기 위해서는 교통zoning제도의 한 방식인 교통특별관리구역 제도의 도입을 통한 강력한 블록별 통행규제가 절대적으로 필요하다고 판단된다. 본 연구의 목적은 서울시에서 $\ulcorner$교통특별관리구역$\lrcorner$ 제도를 성공적으로 도입하기 위해 아시아-유럽 정상회담 개최장소인 강남의 ASEM지구에 대한 사례연구를 통해 그 적절한 시행방안을 사전적으로 검토하는데 있다. 본 연구결과 특별관리구역의 공간적 범위를 크게 하고 통과교통도 규제하는 것이 교통개선효과 측면에서는 가장 좋은 것으로 나타났다. 그러나 공간적 범위를 크게 할 경우에는 직접적으로 혼잡유발에 책임이 없는데도 불구하고 규제의 대상이 되는 형평성 문제가 발생할 수 있다. 한편, 공간적 범위를 혼잡유발시설 주변으로 축소하고 도착통행만을 규제할 경우에는 전이교통이 늘어나서 규제의 효과가 잘 나타나지 않고 오히려 규제대상만 불편하게 하는 문제점이 나타났다. 연구결과 나타난 문제를 보완하기 위해서는 가능한 구역의 범위는 혼잡유발정도가 큰 건물이 밀집되어 있는 블록 주변으로 한정하되, 교통개선효과를 높이기 위해서는 구역 내를 통과하는 교통도 규제의 대상이 될 필요가 있는 것으로 판단된다. 통과교통도 규제의 대상이 되기 때문에 구역을 범위를 설정할 때 구역 주변도로의 교통상황을 신중하게 고려해야 할 것으로 판단된다.

There are many traffic problems in a city such as parking, traffic jam caused by traffic induction facility. Therefore it is essential to demand for traffic demand management to building's owner whose building location causes traffic induction. According to the 90s traffic policy, government collects fee for traffic induction facility through traffic policy management and they encourage the building owner to join reduction of traffic jam program by reduction of traffic induction fee. However there are not many buildings owner joined this program because the program is not ghat beneficial. For example, if government set out parking guidance system (part of parking demanding system) in a city, it will reduce to 20% of traffic induced contributions but t can be used only once a year, so it is not efficient to used even it is valuable for about 10 years. In particular, according to the economic efficiency analysis, evaluate economically as net present value (NPV) to 2,160.44 million won, ratio of benefit/cost (B / C) to 2.44 during 10 years. Therefore this research will find out what is necessary for parking guidance system.

각종 교통사고로 인한 피해를 최소화하고 예방하기 위해서는 교통사고 유발요소에 대한 정확한 정보와 지식을 파악하고, 안전한 이용방법의 정확한 숙지가 요구된다. 그러기 위해서는 어린이를 포함한 전 국민을 대상으로 하는 교통안전에 관련된 교육프로 그램 및 시설물이 종합적으로 구성된 체험교육장이 절대적으로 필요하다. 그러나 현재국내에는 종합적인 교통안전 교육시설이 미흡한 실정이다.(중략)

In 2008, Korea has observed total 215,822traffic accidents Although the number has decreased since then, the crash rate is still higher than those of other advanced countries. In particular, high rate of pedestrian accidents occurred on urban streets is recognized as a serious problem. The previous studies, however, are not entirely considerate of accident factors by accident type. Inspired by the fact, this study analyzes factors affecting traffic accident by accident type. Using the accident data collected on urban streets in Seodaemun-gu, this paper classifies the accidents into two groups (i.e., vehicle-vs-vehicle and vehicle-vs-person crashes), and analyzes relationships between severity and exogenous variables. For the analysis, Structural Equation Modeling (SEM) is employed to estimate relationships among exogenous factors of traffic accident by each type on urban streets. The resulting model reveals that roadway related factors are highly correlated with the severity of vehicle-vs-vehicle crashes whereas environment factors are with vehicle-vs-person crashes.

To accommodate urban concentration of population, multi-purpose super-tall buildings have been introduced, but they induce many travel demands causing regional traffic problems. While several travel demand management policies such as transit promotion or parking limits are presented to alleviate such problems, transportation infrastructure are still insufficient to meet high demands. In this study, super-tall buildings are categorized by scale and purpose, then mode-specific derived demand is estimated using modal share of each category. Optimal transportation infrastructure level is determined by condition-based average changing amount yielded by street network delay (in case of road) or the number of transit routes (in case of transit).

This paper attempts to find an improved organizational structure for operating the traffic safety facilities. Currently, police is in charge of the facilities while the local government is in charge of its budget. By doing so, many inefficiencies and problems occur in these things. A delphi technique is used to survey these inefficiencies. Problems, and improved role and organization by three expert groups in local government, police and university The survey results are analyzed by each expert group as well as by the total group. The multidimensional scaling technique is also used. The most preferable answer is to newly establish a traffic experts' agency under the local government. The second preferable answer is to set the current traffic police under the control of the local government.

The purpose of this study is to simulate the suitable space of parking lots for Mass traffic instigating facilities in Pusan. After the suitable scale of parking lots estimate using GPSS, one of the Queue Simulation, with the average arriving time and the average parking time at parking lots, the formula is simulated by the Regression model to relate a total floor area and the suitable number of parking lots. The improved criteria or present parking lots is needed to prevent the unnecessary vehicles and improve the efficiency of land use. The suitable scale of parking lots estimate just with the state of using the parking lots in this study. but it is necessary to consider land use, traffic condition, commercial area etc.

현재의 철도, 도로망 등의 각 중심측 및 간선측의 주요 교통시설은 이미 포화 상태가 되어 물류비용의 증가를 초래하고, 배기 가스를 비롯한 환경오염 문제를 유발하고 있기 때문에 이에 대한 해결방안이 시급한 실정이다. 이러한 상황에서 고속전철은 대기 오염을 일으키지 않으면서 신속$.$대량 수송이 가능하여 교통량을 대량으로 흡수할 수 있는 주요 교통 수단으로 인식되고 있다.(중략)
