Train Control System Requirements Analysis for Flexible Train Operation

초록

Conventional urban railways are in operation with fixed train-sets focused on operators without considering different traffic demands according to space and time variation. This causes to decrease transport share of railways by triggering an increase of passenger travel time depending on traffic congestion, headway and transfer during peak hours in a station. Although urban railway has advantages of economics and traffic efficiencies, the reasons why traffic consumers avoid it are transfer resulting from lack of a direct connection to destination and greater traffic congestion in station and travel time resulting from the transfer. Urban railway operator takes actions with passive ways such as headway adjustment according to time. This passive reaction, however, cannot satisfy expectations of urban railway consumers who want to travel without stops and transfers like a private car. Therefore, both urban railway consumers and operator are realizing the necessity for technology of new urban railway operation focused on consumers. This paper describes requirements of train control system development for train operation concentrated on users.
