Induction type street crossing assisting method for visually impaired people at large-scale intersection

The invention discloses a large-scale intersection visually impaired person induction type street crossing assisting method which comprises the following steps: firstly, arranging infrastructures and acquiring basic data; secondly, the processor calculates basic parameters based on information interaction of sensor data and bracelet data, judges whether a signal period needs to be adjusted or not and calculates a signal timing adjustment scheme; then, a voice prompt output scheme is determined according to a calculation result; and finally, judging whether the visually impaired person finishes crossing the street or not, and if so, ending the signal voice prompt output. According to the large-scale intersection street-crossing assisting method for the visually impaired people based on the induction type equipment in the flat peak period, the street-crossing safety of the visually impaired people can be effectively improved in the flat peak period, meanwhile, the street-crossing decision-making difficulty and
