The method includes steps of receiving a detection information outputted from an on-vehicle detecting device, wherein the detection information includes a host-vehicle absolute coordinate, a host-vehicle course, a host-vehicle speed, a relative speed between an object and the host vehicle, and an initial relative coordinate between the object and the host vehicle; respectively performing matching procedures to the host-vehicle absolute coordinate and the initial relative coordinate by respectively adding estimated coordinate shifts to obtain a matched host-vehicle absolute coordinate and a matched relative coordinate; performing a coordinate rotation transformation to the matched relative coordinate to obtain a matched transformed coordinate; merging the matched host-vehicle absolute coordinate and the matched transformed coordinate into crossroad-section map data to form crossroad dynamic map data; and sharing the crossroad dynamic map data.",
