Detecting Hazardous Vehicles and Disseminating Their Behavior in Urban Areas

Speeding cars and motorcycles constantly varying their speed, changing lanes or committing other apparent traffic violations as well as police cars and ambulances responding to incidents, are examples of vehicles that demonstrate hazardous traffic patterns. We propose a detection and a broadcasting protocol that run on top of vehicular ad-hoc networks and effectively alert drivers about such hazardous vehicles in urban environments.
