Abstract

In short-term traffic volume clustering, one important issue is the representation of traffic profiles. This article focuses on how the LOESS smoothing technique enhances the clustering effect and what the best value of parameter span of LOESS is. This article used K-Means clustering algorithm and compared the clustering effect using raw data and smoothed data. The experiment result shows when the traffic profiles are slight smoothed, the clustering effect enhances from 39.15% to 66.48%. And the best range of parameter span is 0.2~0.4 to keep the balance of clustering effect and profiles details. This article verifies the promotion effect of LOESS smoothing technique in short-term traffic volume clustering and gives advice on the best value of LOESS parameter.
