According to the formula:

L_i-L_i+1＝M_i；

the result M obtained by calculation_iLess than 0, Li minus L is selected_i+2；

Obtaining a formula:

L_i-L_i+2＝M_i+1；

the result M obtained by calculation_iGreater than or equal to 0, L is selected_i+1Minus L_i+2；

Obtaining a formula:

L_i+1-L_i+2＝M_i+1；

i in the formula is less than or equal to n-2, when the subtraction is carried out for the last time, a subtracted number is selected when the calculated result is less than 0, the subtracted number represents the distance of the nearest rider, and the subtracted number is selected when the calculated result is greater than or equal to 0, and the subtracted number represents the distance of the nearest rider;

the help seeking unit sends an independent reminding bullet frame to the mobile phone terminal of the nearest rider selected finally to remind the rider of being the person nearest to the rider needing rescue.
