METHOD AND DEVICE FOR SELECTING INFORMATION TRIGGER POSITION

摘要

The invention discloses a method and device for selecting information trigger position, which relate to the field of intelligent traffic information service, and can display graphical real-time traffic information on a terminal in appropriate time. The method comprises: selecting a pre-estimation information trigger position (101); acquiring a reference speed at which a vehicle runs from the pre-estimation information trigger position to a graph representation position according to a pre-estimation information trigger distance between the pre-estimation information trigger position and the graph representation position and the historical time recording value during which the vehicle runs for the pre-estimation information trigger distance (102); acquiring an appropriate practical information trigger distance according to the reference speed and a preset reference time, and thus determining an appropriate practical information trigger position (103).: Fig. 1
