Abstract
The present invention provides a method and system for segmentally limiting the speed of a vehicle. The method comprises: receiving characteristic parameters of a route sent by a vehicle monitoring platform, and respectively expanding a plurality of road segments of the route into a plurality of rectangles; dividing the plurality of rectangles into blocks sequentially; calculating a minimum enclosing rectangle of the at least two rectangles, and counting vertex information of the minimum enclosing rectangle of each block so as to establish a hash table; obtaining an instant longitude and latitude of a moving vehicle, searching in the hash table so as to determine a block where the vehicle is located, and judging a road segment where the vehicle is currently located; and comparing a current speed of the vehicle with a limiting speed of the road segment where the vehicle is currently located, judging whether the vehicle exceeds the limiting speed.
