Considering the disabled, the elderly and children needs ( especially the disabled and the blind paraplegic disabled ) to travel for blind people with disabilities , the design of the subsidiary facility design is specially designed Blind ; rely on a wheelchair to travel for lower limb paralysis people with disabilities , the design specially designed curbs ramps.
