Using Image Pattern Recognition Algorithms for Processing Video Log Images to Enhance Roadway Infrastructure Data Collection

This Innovations Deserving Exploratory Analysis (IDEA) project developed generalized algorithms to automatically detect and recognize more than 670 different types of traffic signs specified in the Manual on Uniform Traffic Control Devices (MUTCD) by using video log images that are widely available. The developed algorithms provide new capabilities for automating the traffic sign inventory by means of batch processing, which significantly reduces the time and cost spent by state departments of transportation for acquiring traffic sign inventory data. Tests show that the developed detection and recognition algorithms are promising for developing an intelligent sign inventory and management system.
