Abstract

The present invention provides a lane matrix model and its construction method, reading method and device, wherein the lane matrix model is characterized in that it includes: lane matrix elements corresponding to lanes in several lane group units in map data; And filling matrix elements, connecting with the lane matrix elements on the row and column where the lane matrix elements are located, so as to form a matrix structure. The invention can realize lane-level navigation guidance, is beneficial to improving the crossing passing speed and reducing the possibility of traffic accidents.

Description

technical field [0001] The invention relates to a lane matrix model and its construction method, reading method and device, belonging to the technical field of navigation. Background technique [0002] In the existing navigation technology, it can only provide route guidance for the road, but for the lanes of the road network, only the lane conditions at the intersection will be displayed, and it will not make judgments on the continuous changes of the lanes ahead of the road, nor will it be accurate. Deduce the lane-level route that the vehicle passes through in order to pass the intersection smoothly. [0003] For example, when a guided vehicle is approaching an intersection and intends to turn left, the existing technology can only prompt the driver that the two lanes on the left in front of the intersection are left-turn lanes, but cannot guide the vehicle on how to reach the above-mentioned left lane from the current lane. turn lane. As far as the driver is concerned,...
