A multi-pattern deep fusion model for short-term bus passenger flow
Yun Bai, Zhenzhong Sun, Bo Zeng, Jun Deng, Chuan Li
Short-term passenger flow forecasting
is one of the crucial components in transportation systems with data support
for transportation planning and management. For forecasting bus passenger flow,
this paper proposes a multi-pattern deep fusion (MPDF) approach that is
constructed by fusing deep belief networks(DBNs) corresponding to multiple
patterns. The dataset of the short-term bus passenger flow is first segmented
into different clusters by an affinity propagation algorithm. The passenger flow distribution of these clusters is subsequently analyzed for identifying different patterns. In each pattern, a DBN is developed as a deep representation for the passenger flow. The outputs of the DBNs are finally
fused by chronological order rearrangement. Taking a bus line in Guangzhou city
of China as an example, the present MPDF approach is modeled. Five approaches,
non-parametric and parametric models, are applied to the same case for
comparison. The results show that, the proposed model overwhelms all the peer
methods in terms of mean absolute percentage error, root-mean-square error, and
determination coefficient criteria. In addition, there exists significant
difference between the addressed model and the comparison models. It is recommended
from the present study that the deep learning technique incorporating the
pattern analysis is promising in forecasting the short-term passenger flow.
