Bus Stop Button / Preventing Misoperation

Bus Stop Button
Bus Stop Button

Children often mishandle a bus's opening button due to curiosity. To solve the problem, We redesigned the button by changing its installing height and operated method.
Before Modification:
The button is installed at a height where a six-year-old child can easily push. The button is pressed horizontally that increases the chance of mishandling.
Modified Design:
The redesigned button is installed at a height of 1300mm to 1400mm, and the passengers may only open the door by pressing the button downward instead of forward; therefore it is not available for children under six.
