Automatic incident detection on freeways based on Bluetooth traffic monitoring

•Developing an automatic incident detection (AID) method for freeways, based on Bluetooth data and an unsupervised anomaly detection approach.•Demonstrating the developed AID method using real traffic data collected by a network of Bluetooth sensors installed in Ayalon Highway, Tel Aviv.•Special emphasis is made in using data provided by Bluetooth sensors without assuming knowledge about incident information.
