According to the method, a
traffic flow time sequence partitioning model based on similar evolution mode clustering and dynamic
time zone partitioning is provided, the dynamic time-space characteristics of
traffic flow changing along with time are tried to be excavated for the first time, and the challenge of
traffic flow time non-stationarity in short-time traffic flow prediction is solved. The invention specifically comprises the following steps: firstly, automatically identifying road sections with similar traffic flow evolution
modes in a road network by using an
affinity propagation clustering
algorithm (APC); and secondly, for the intra-day evolution difference of the traffic flow, performing dynamic
time zone division on the traffic flow in the similar evolution mode by using a curvature K-Means
algorithm, and mining the space-time state characteristics of the road network traffic flow in a deeper level; after similar mode identification and automatic
time zone division, performing modeling on traffic flows in different time zones in different
modes, and quantifying the state information of the traffic flows, so that the prediction precision of the model is more accurate; and finally, verifying the validity of the provided model by using a real
data set.
