A Study on the Quantitative Analysis to Determine the Optimal Train Service Patterns and Train-Sets Necessary under SKIP-STOP Operations in the Metro Railway

광역철도의 SKIP-STOP 운영에서 최적 열차패턴 및 차량소요 산정을 위한 정량분석 연구

Recently, in the metro railways, researches on the skip-stop operation and development of the double deck train-set are active, which is to improve the service quality through reducing the passenger travel time and suppling seating service. Constructing new line or reforming the existent line needs huge amount of budget. Therefore, previous to start these large scale projects, scrutiny on benefit improvement, cost reduction and those optimal trade-off is indispensable. In this paper, a quantitative analysis to determine the optimal train service patterns and train-sets necessary is proposed, under the skip-stop operation condition in the metro railways. The analysis models are formulated in mathematical programming model, and tested validity using the LINGO 7.0.
