Braking point determining method of rail transit train operation path

The invention discloses a braking point determining method of a rail transit train operation path. The braking point determining method comprises the following steps: determining a train operation path; confirming speed limiting sections for which braking points need to be set in sequence; determining highest operation speed and traction distance of the train; if the highest operation speed is equal to a limiting speed, obtaining a train braking distance; if the distance difference is more than an error threshold, correspondingly changing the traction or constant speed operation distance into half of the difference; repeating the steps; if the highest operation speed is less than the limiting speed, reducing the highest operation speed by half of the difference; figuring out train traction and braking distances; if the distance difference is more than the error threshold, repeating the calculation by using a processing method that the highest operation speed is equal to the limiting speed; and finally, detect
