Abstract
The present disclosure relates to systems and methods for identifying a closed road section. The systems may obtain a first heat map representing a first density of tracked vehicles in a target area over a first time period and a second heat map representing a second density of tracked vehicles in the target area over a second time period; determine a difference map between the first heat map and the second heat map; determine one or more candidate regions based on the difference map; identify one or more candidate links associated with the one or more candidate regions in a road network map; determine one or more confidence levels associated with the one or more candidate links based on the one or more candidate regions; and identify one or more closed road sections based on the one or more confidence levels.
