이 연구는 장태산 휴양림에서 탐방로의 분석을 통해 추후 휴양림의 탐방로 조성에 필요한 기초자료를 제공하기 위하여 수행되었다. 장태산 휴양림의 기존 탐방로 A와 B의 거리는 1,273m와 965m이었으며 평균물매는 각각 9%와 14%로 조사되었다. 평균 칼로리 소비량은 탐방로 A를 올라갈 때와 내려갈때가 각각 140kcal와 104kcal이었으며 탐방로 B의 경우는 올라갈 때와 내려갈때가 각각 132kcal 와 89kcal로 조사되었다. 평균보행시간은 각각 약 18분과 15분으로 조사되었다. 신규 탐방로 노선 선정의 기초자료를 제공하기 위하여 GIS프로그램인 IDRISI를 이용하여 장태산휴양림의 DEM을 구축한후 탐방로의 노선을 선정하였다.

우리나라에서는 그동안 급속한 경제발전과 함께 많은 SOC 건설공사가 이루어졌으나 환경성의 고려와 보존에는 미흡하였다. 그러나 경제가 발전되고 국민의 의식수준이 향상됨에 따라 환경에 대한 관심과 중요성이 높아졌으며, 친환경적인 건설의 요구가 증대되고 있다. 이러한 추세에 따라 친환경 건설을 위한 많은 연구와 노력들이 진행되고 있지만, 타 분야에 비해 정보화 및 전산화, 특히 GIS의 활용은 많이 미흡한 실정이다. 따라서 본 연구에서는 초기 건설계획 및 설계분야에 최신 GIS 기술을 접목ㆍ활용함으로써 환경성이 고려된 국토개발을 지원하고자 하였다. 이를 위해 도로건설분야를 대상으로 하여 다양한 대안노선들의 환경성을 비교ㆍ검토하여 최적의 노선선정을 지원하고, 선정된 노선에 대하여 영향평가분석을 수행할 수 있도록 시범시스템을 개발하였다. 기존의 환경성 검토ㆍ평가방법이 종이도면과 서술적인 기술에 의지했던 반면, 본 시스템은 수치지도 및 위성영상을 활용한 다양한 GIS 공간분석결과를 2차원 또는 3차원적으로 디스플레이하여 객관성과 효율성을 향상시키면서 시각적 효과를 높여줄 수 있다는 장점이 있다.

As interest in green growth picks up, the importance of bicycles which are an environment friendly means of communication has been magnified. However, bicycle routes which are the base of bicycles are designed without considering topographic elements and thus many users are experiencing inconvenience in using bicycles. The present study presents a routing technique to select optimal routes when selecting routes in commuting to school utilizing bicycles. To this end, a formula for optimum route calculation considering slope and intersections was drawn and a method to select optimum routes by applying modified Dijkstra Algorithms was studied. According to the results, the bicycle routes for commuting to school should be selected by the shortest time rather than the shortest distances to the destination, because it required reach the destination faster. Therefore when selecting the routes, it must be based on the shortest time considering waiting time due to crosswalks or crossroads and speed variations due to slopes.

This study was aimed at suggest a proper planning method to select a optimal forest road network in mountains forest using GIS(Geographic Information System). To examine the field applicability, the method was applied to the National Forest at Mt. Kumsan in Namhae-gun, Gyungsangnam-do. The main results from altogether six alternative road route plans were derived from these criteria obtained the alternative route plan No.2 has two layout criteria, longitudinal gradient and earth work volume, and it showed similar pattern of existing forest road network which was designed mainly ground slope and longitudinal gradient. The alternative route plan No.6 has four criteria, longitudinal gradient, earth work volume, investment effect and landscape impact. It was different for the lowest forest road density among the alternatives and the pattern of the forest road layout was radial form, which was also quite different to other alternatives. For optimal forest road network planning, GIS provide the efficient and resonable solutions for decision making to provide the support for evaluation about various alternative road networks. If detailed inventory and relevant data are provided and also clear and objective indicators for evaluations are set up, it could be applied to preliminary analysis and detail planning stage to prevent undesirable effect such the land slide and soil erosion due to inadequate planning for forest road network.

The purpose of the paper is to make the three dimensional road simulation model based on the digital photogrammetry and GIS techniques in the middle of Halla mountain of Jeju island. To do this, we generate DEM (digital elevation model) and digital ortho image using GIS tools such as Arc View, Imagestation and MGE module. In GIS, the overlay map schemes combining of the hill shade, the land slope and aspect were applied. Based on the processes, we can build the best three dimensional road line along the hill side of the island. From the results, we also found that the derived DEM from digital ortho image and the GIS technique were very useful for choosing the best three dimensional road design before the real road construction works in Jeju island.

This research attempts to develop 4D CAD function to support optimal road design by expanding the existing 4D CAD utilization system, which focused on construction phase, to the design phase. The functions such as earthwork simulation for selecting of road alignment, alternative route simulation and structure type simulation were suggested as functions to support road design. Through those virtual reality (VR) functions, visual confirmation of the condition of route and earthwork Is possible by the developed system, and an optimal alternative route can be selected by carrying out layout simulation of the alternative route. The functions presented in this research provide the decision making tools based virtual model for efficient support to road design.

This paper introduced Railway Network Design Problem (RNDP) to provide priority decisions on high-speed railway investment scenarios defined by various network segments and train systems. The RNDP optimizes the objective functions of minimize total travel time. Results show that the priority of high-speed railway investment is found to be East-west, West-coast, and South-coast line respectively. An entirely new line built with 400km/h is found to be the best alternative to East-west line. Regarding West-coast and South-coast line, the combined alternative of upgrading Geolla and Kyeonjon line with 200km/h and building a new line with 400km/h and 350km/h for remains of each line is the best.
