Effort has been given to improve demand forecast methodology of rail system since it can have great impact on project evaluation of rail system investment. However most of demand forecast softwares developed in western countries where concerns have been provided mostly to private transport and they should be updated in order to reflect our country's situation accurately. Therefore, this paper aims, especially focusing on rail system, to do comparison analysis of oversea's passenger demand forecast softwares and provide some ideas to develop the updated demand forecast system which enables to reflect our country's situation accurately. Main conclusions are that we will need to have well described model for real situation. So we will have to study for these aspects for travel demand forecasting system and develop the package architecture.

AGT(Automated Guide-way Transit System) was introduced to satisfy the every increasing need for improved urban transportation. The AGT system is classified as medium distance and demand capacity mass transit being introduced for such area with inadequate passenger demand for railway construction but excessive demand for bus service. To decrease initial investment cost it is important that we have to secure the technology system of Light Rail Transit for Korea environment. By utilizing the finite element analysis, the result in this paper is enough to satisfy the strength whish is required. Also for the purpose of safety, it is decided the thickness and frame structure of the undeframe section through the analysis. It is known that carbody is no problem for required design conditions.

The down town passage segment which follows in the straight line which follows recently in high speed of the railway and rail construction is increasing. Also according to quality of life improvement of the citizens whom follows in national income increase the resident demand only becomes larger day by day about a environmental creation which is comfortable and house environmental etc. Demand of the citizens is not the problem of today yesterday about like this railway mean of transportation and with the fact that continuously will increase in future. This study is to predict and reduce railway noise from the conventional PSC-beam bridges which passes through urban areas under the government strateges of speed and weight increases of railway. The purpose of this study is to recommend a proper noise prediction method for designing pleasant roadside environments. The railway design including existing line reconstructions should minimize curved alignment to increase train speed to 180~200km/hr under the government's long-term planing such as the 4th Comprehensive National Development Plan (2000~2020), National Intermodal Transportation Plan (2000~2019) and National Railroad Network Establishment Plan (2006~2015), Since the PSC-beam bridges are mainly used for bridge structures urban areas, noise measurements were performed and analyzed to recommend the noise prediction methods for each type and speed of train respectively.

수도권에는 49%로의 인구가 집중되어 있고, 광역교통망이 갖춰져 있지 않아 성남축, 고양/파주축, 인천/부천축 등에는 교통량 증대로 교통혼잡, 통행시간지연 등의 교통문제가 발생되고 있다. 고양/파주축에는 대중교통분담율이 51.2%이고, 송용차는 48.8%로 높은 상태이며, 지하철은 27.3%로 낮고, 택지 개발계획을 통해 53만인 거주계획 등이 있어 광역철도교통이 요구되고 있다. 강남$\sim$일산간 37.8Km/h에 급행철도 도입에 관한 연구를 수행한 결과, 150Km/h의 급행열차를 운행할 경우는 강남에서 킨텍스까지 표정속도는 103Km/h이고, 소요시간은 약 23분정도이다. 본 사업노선의 교통수요를 분석한 결과 일일 237,000명 정도(환송 포함)로 예측되었고, B/C는 1.08로서 사업의 경제적 타당성은 있는 것으로 분석되었다.

It is very difficult to find optimal train operation plan when analyzing the economic investment using traditional railroad travel demand estimation method. Train operation plan depends on travel demand and vice versa. To solve this problem, this study suggests a demand estimation method to address an optimal train operation scheme with the modal spilt using initial train operation plan and trip assignment.

최근 철도 서비스를 개선하고자 기존선을 복선 및 전철화 하는 등 철도네트워크 기능강화사업이 활발히 추진되고 있다. 이를 배경으로 본 논문에서 급행철도와 같이 새로운 철도 운영서비스가 제공될 경우 타 교통수단으로부터 얼마의 전환수요가 발생될 것이며, 철도이용형태는 어떻게 변화될 것인지? 등 앞으로 건설될 대구권 광역철도를 대상으로 SP와 RP데이터에 의한 전환수요 예측방법의 적용성을 검토하였다. 모형 구축결과, 기존 SP와 RP데이터를 결합하는 동시적 모형과 순차적 모형이 모두 유용하여 총통행시간과 통행비용의 파라미터 추정치가 충분한 설명력을 나타내고 있으며, 동시적 방법이 보다 효율적으로 분석되었다. 특히 RP+SP의 결합모형의 타당성을 더욱 높이기위해서 RP데이터를 비례적으로 적용한다면, 철도요금과 통행시간 설정에 따라 전환수요를 쉽게 파악할 수 있을 것이며, 대구권 광역철도를 비롯하여 타 지역에서도 보다 실용적으로 적용할 수 있을 것으로 판단된다.

직접수요모형은 전통적 4단계 수요예측방법론보다 적은 비용과 시간으로 기본구상단계에 적합한 분석방법이다. 본 연구에서는 기존 읍면동 기준보다 약 1/24 공간적 크기를 가진 소지역(집계구)단위 사회경제지표를 활용하여 지방 광역권 12개 도시철도 노선을 대상으로 직접수요모형을 구축하여 예측수요를 실적자료와 비교 분석하였다. 하지만 통계적 분석에 의존하는 직접수요모형은 역별 특성을 반영하지 못하여 승차인원 예측에 한계가 있으며 본 연구에서는 승차인원에 영향을 미치는 인자를 찾아내고 각 영향인자들의 표준화 및 기준을 제시하였다. 특히 사회적 이슈가 되고 있는 경전철 노선 54개 역을 대상으로 실증분석하여 역 특성 기초자료 수집, 분석, 보정방안에 대해 논의하였다. 경전철 역을 대상으로 제안된 방안의 적용성을 검토하였고 향후 직접수요모형의 활용성을 높일 수 있을 것으로 기대된다.

The purposes of this primary study are the selection of rail station and train operation management techniques for express-rail operation service at the convectional railway electrification. For these analyses, we used the KNR statistics and KROIS data of rail stations and train users by rail line. Therefore, we chose the important stations for express-rail operation of Kyongbu conventional rail line (esp. Seoul-Jochiwon section) through the rail transportation demand. and then, suggested primary operational management plan thorough the effects analyses of decreasing total travel time and increasing transportation demand by train speed-up. This study has some bounds and limits for proceeding, as it does, we excluded as followings: the conditionals of fate system, headways and train diagram, economic/financial analysis and technological assessment, and other railway technological infrastructures and a certain railcar specification, etc. . We propose to enlarge this study into a feasibility study of express or skip-stop operation service and compatible vehicle system decision considering with the best possible investment rail line, furthermore. in front of Kyongbu (Seoul-Busan) high-speed rail open in 2004, we have to try to progress the efficiencies of railway operation applying various train operation management plan.

Demand forecasting for railroad traffic is fairly important to establish future policy and plan. The future demand of railroad traffic can be predicted by analyzing the demand of air, marine and bus traffic which influence the demand of railroad traffic. In this study, forecasting the demand of railroad traffic is implemented through neural network using the demand of air, marine and bus traffic. Estimate accuracy of the demand of railroad traffic was shown about 84% through neural net model proposed.
