METHOD AND APPARATUS FOR OBTAINING AREA SPEED LIMIT VALUE AND TERMINAL DEVICE

The present disclosure provides a method for obtaining an area speed limit value. The method includes: mapping, to a coordinate system, a track section on a train running line in electronic map data; respectively storing, into a temporary speed limit information list and a constant speed limit information list in a one-to-one correspondence mode, speed limit data of a temporary speed limit and speed limit data of a constant speed limit of the train in the track section according to coordinates of the track section in the coordinate system; combining speed limit data in the temporary speed limit information list with speed limit data in the constant speed limit information list to obtain a strictest speed limit list of the train; and obtaining, by searching the strictest speed limit list, a strictest speed limit value of an area corresponding to a real-time coordinate position of the train.
