Abstract
Although rail transportation is conventionally considered to be environmentallyfriendly,
currently research is being carried out globally to find ways to improve
energy-saving in rail transportation. Development of an energy management
system for railways and new transport systems including the BRT (Bus Rapid
Transit) system has begun. The railway energy management system manages
and controls the use of energy for transportation as well as train operation.
An EE (energy efficient) train traffic control system is being developed in
order to reduce energy consumption in train traffic operation. This system is
mainly useful for urban railways. The control system reduces consumed running
energy by assigning several seconds of the scheduled margin times at platforms
to inter-stations. While taking care about delay of the trains, the control system
adjusts the arrival-and-departure time at stations without making passenger
aware of the difference from the usual.
The following methods can be considered in utilization; 1) drivers judge and
lengthen the running time appropriately according to the train operation
condition of routes; 2) the ground operation control device grasps train traffic
conditions and decides the arrival time at the next station and then orders the
time to each train using a ground-vehicle transmission system, while drivers
operate according to the guidance by the on-board driving assistance equipment;
3) trains run with automatic train operation equipment according to the order
from the ground operation control device.
By computer simulation for typical urban transport lines, the evaluation of an
EE train traffic control algorithm was carried out. As a result, it was confirmed
