Query: TSSRGCN: Temporal Spectral Spatial Retrieval Graph Convolutional Network
  for Traffic Flow Forecasting   Traffic flow forecasting is of great significance for improving the
efficiency of transportation systems and preventing emergencies. Due to the
highly non-linearity and intricate evolutionary patterns of short-term and
long-term traffic flow, existing methods often fail to take full advantage of
spatial-temporal information, especially the various temporal patterns with
different period shifting and the characteristics of road segments. Besides,
the globality representing the absolute value of traffic status indicators and
the locality representing the relative value have not been considered
simultaneously. This paper proposes a neural network model that focuses on the
globality and locality of traffic networks as well as the temporal patterns of
traffic data. The cycle-based dilated deformable convolution block is designed
to capture different time-varying trends on each node accurately. Our model can
extract both global and local spatial information since we combine two graph
convolutional network methods to learn the representations of nodes and edges.
Experiments on two real-world datasets show that the model can scrutinize the
spatial-temporal correlation of traffic data, and its performance is better
than the compared state-of-the-art methods. Further analysis indicates that the
locality and globality of the traffic networks are critical to traffic flow
prediction and the proposed TSSRGCN model can adapt to the various temporal
traffic patterns.
