Proposals of High-Speed and High-Dencity Train Operation System by On-Board Pattern Control ATC.

Demand for rail transportation is increasing rapidly in the big city areas. However for various reasons such as environmental concerns, it is not easy to expand capacity. In order to expand capacity and speed up service, a new system must be introduced. For the Automatic Train control (ATC) system, we peopose the on-board pattern control ATC system (referred to as A-ATC) be utilized. It achieves higher transportation efficiency through high-speed, high-dencity operation, while maintaining current levels of safety. The A-ATC system allows the deceleration control system to be set individually for each train, according to the vehicle type. By upgrading vehicle performance A-ATC upgrades performance of the ATC system as whole. We will be able to introduce the A-ATC system gradually, by minor modification of the current ATC system.
