Research Tries to Replace Human Analysis.(probabilistic neural network may be used in traffic incident detection)(Brief Article)
Advanced Materials & Composites News, December, 1999
Baher Abdulhai, assistant professor and manager of intelligent transportation systems (ITS) research for the University of Toronto (Department of Civil Engineering, University of Toronto, Toronto, Ontario, Canada M5S 1A4; Email: Baher@ecf.utoronto.ca) presented a paper discussing automatic incident reporting technologies. Abdulhai discussed using different artificial neural net algorithms to analyze highway data and correctly identify an incident.
The system studied in this work is a probabilistic neural network (PNN). PNN uses probabilistic models to determine if an incident has occurred. The PNN needs a "smoothing" factor called "sigma" for each parameter (such as time or distance between vehicles, speed, etc.) modeled. Using PNN, a human has to determine...
