To make use of a human approach report informatization energization device in the platform environment of the simulated station and to check the upper limit speed of the walking speed of an approaching individual who the visually handicapped can avoid a collision.
An experimental single-arm study.
General community public space.
Participants (or Animals, Specimens, Cadavers) :
19 blind people as a volunteer sample were requested cooperation from the Blind and Handicapped Association in Japan.
As a placebo that the device did not work randomly, an intervention was to the device to function.
Main Outcome Measure(s) :
The walking speed of the visually impaired and the speed of the approaching pedestrian was calculated. The time from the start of the initial approach of the approaching individual to just before the collision and the speed in the immediately preceding deceleration direction were obtained.
The trial conducted 112 trials. Under the condition that the user of the apparatus walks at approximately 0.9 m / sec,
Subjects succeeded in "preparing stop" before the collision, the average speed of the approaching individuals was 1.25 m / sec,
subjects failed to "stop" before the collision, the average speed of the approaching individuals was 1.47 m / sec.
The Successful speed for avoiding a collision was approximately 1.25 m / sec. It would also be necessary to develop an educational method to further improve this condition and to improve practicality based on clinical adaptation range and limit.
