Abstract: Most existing incident detection algorithms use inductive loops, a relatively old sensor technology that obtains data at specific points along the roadway. This paper discusses the use of vehicle to roadside communications (VCR), the enabling technology for electronic toll collection, to highway incident detection. We describe how point-to-point data (such as travel times ) provided by VCR can be used as the basis for more successful incident detection than before. In particular, we describe how VRC data can be used to develop several new patterns-based algorithms that use VRC. Preliminary results are given along with suggestions for further research.
