Other AbstractThe present invention relates to a multi-scale space-time hot point path detection method based on rapid road network modeling. The multi-scale space-time hot point path detection method comprises: constructing a road network by using large-scale track data; based on the constructed road network, carrying out road matching on the track; converting the track point sequence into the grid sequence covering the road; and carrying out hot point detection. According to the present invention, the multi-scale space-time hot point path detection method under the road-network-free topology support is provided so as to achieve the rapid road network construction based on the large-scale track data and the effective detection on the high flow path in the road network; and the high precision road network topology support is not required, the particular type of the data is not required, the positioning data of any existing positioning equipment can be used, and advantages of low economic input, rapidness, high efficiency and the like are provided.
