  Online traffic news web sites do not always announce traffic events in areas
in real-time. There is a capability to employ text mining and machine learning
techniques on the twitter stream to perform event detection, in order to
develop a real-time traffic detection system. In this present survey paper, we
will deliberate the current state-of-art techniques in detecting traffic events
in real-time focusing on five papers [1, 2, 3, 4, 5]. Lastly, applying text
mining techniques and SVM classifiers in paper [2] gave the best results (i.e.
95.75% accuracy and 95.8% F1-score).
