Enhancing Automatic Incident Detection Techniques Through Vehicle To Infrastructure Communication

One of the fundamental requirements of a traffic management system is the ability to determine when an incident has occurred so that proper responses can be initiated. Automatic incident detection (AID) has been considered a method for quickly detecting potential incidents on the road. Although vehicular ad hoc networks (VANETs) started mainly for safety applications, surprisingly a very few work have been done in VANETs for automatic incident detection while most of the research went for developing routing protocols and privacy techniques. In this paper, we introduce a novel incident detection technique for non dense traffic flow by taking advantage of communication between cars and some roadside infrastructure installed on the road every mile or so. The proposed technique can provide a great enhancement to the existing AID techniques specially under sparse traffic where most of them fail to detect non blocking incidents.
