Problems solved by technology
At present, most of the traffic light positions are usually provided by map vendors, but due to the limitation of the collection cycle, the update cycle of the traffic light position data provided by map vendors will also be longer, which will lead to delays in the traffic light data of the map application in the terminal , and then errors occur when providing route planning and navigation to users, which affects user experience

The present invention provides a method and device for mining traffic light data based on trajectory data. The method includes: collecting data information of each location point in a designated area and driving trajectory data within a preset range of each location point; obtaining the In the driving trajectory data, the driving trajectory data of each traffic light position point within the first specified range is used as the first driving trajectory data; the driving trajectory data within the second specified range of each non-traffic light position point in the driving trajectory data is obtained. Trajectory data, and as the second driving trajectory data; by analyzing the remaining driving trajectory data outside the first driving trajectory data and the second driving trajectory data in the driving trajectory data, determine Unmarked traffic light location points. Based on the method provided by the embodiment of the present invention, the location of suspected traffic lights can be known accurately and in time, and accurate route planning and route navigation can be provided to users subsequently.
Description
technical field [0001] The invention relates to the technical field of data mining, in particular to a method and device for mining traffic light data based on trajectory data. Background technique [0002] With the improvement of people's living standards, personal vehicles are gradually increasing. In addition, with the development of network technology, people usually rely on electronic maps for route query and navigation when traveling. As an important traffic facility, traffic lights play a pivotal role in traffic route planning. At present, most of the traffic light positions are usually provided by map vendors, but due to the limitation of the collection cycle, the update cycle of the traffic light position data provided by map vendors will also be longer, which will lead to delays in the traffic light data of the map application in the terminal , and then errors occur when providing route planning and navigation to users, which affects user experience.
