Abstract
The present disclosure relates to systems and methods for monitoring traffic congestion. The systems may perform the methods to obtain traffic data associated with speeds or locations of a plurality of vehicles at a first time point; determine a plurality of congested links based on the traffic data; determine one or more congested areas by searching for congested links that are topologically close and clustering the congested links generated by the search; for each of the one or more congested areas, determine whether the congested area is a normal congested area or an abnormal congested area; and display congestion information associated with at least one of the one or more congested areas, wherein the congestion information may include a designation indicating whether the at least one of the one or more congested areas is the normal congested area or the abnormal congested area.
