Description
Method for traffic anomaly detection using STM is presented. A novel distance metric is proposed because standard metrics are inapplicable for the anomaly detection when using the STM.
Summary
- A novel approach for measuring the anomaly level on the road networks using GPS traffic data Speed Transition Matrix (STM)[1] is a novel traffic data technique used for traffic-related analysis.
- In this article, the method for traffic anomaly detection using STM is presented.
- Comparison of the proposed metric with other common metrics (Image by: The proposed metric based on the distance between the COMs of the observed STM and the median STM, which represents the normal traffic conditions, is presented.
