Abstract
In the large cities of Asian countries, the traffic flow at many
intersections is controlled by traffic signals. Most of the
vehicles there are obliged to stop or to decrease their mean speed.
For the purpose of reducing the fuel consumption of vehicles, the
authors paid their attention to the method of passing through a
series of traffic signals and carried out the experiments for
several traveling modes of the vehicles.
As a result, we proposed to the drivers that they drove
according to the controlled-traveling-mode which consisted of
controlling the speed, the acceleration and the deceleration of the
vehicle according to the time interval of each traffic signal. When
a driver was forced to run in the controlled-traveling-mode instead
of the ordinary- traveling-mode, the fuel consumption of the
vehicle improved about 20 percent although the traveling time was
the same. The improvement was 10 percent for a group of traveling
vehicles. The improvement for the actual traveling on the road
could be also attained successfully, when the driver was warned
beforehand and given information of upcoming signals by the
subsidiary-device.
