Punctual train operation with energy-saving Driving Advisory System in dense traffic railway

This paper describes a concept based on energy-efficient train operation technology. It is known that the energy-saving train driving operation for a train takes the form of an operation of power-coast-brake. However, drivers cannot operate in such strategy when the previous train delays. Some drivers experientially drive trains without stopping between stations. But it is very difficult for less-experiential drivers to drive without stopping stations. We have developed prototype hardware and software for helping driver's operation and evaluated energy consumption and running time by numerical simulation.
