The objective of this project is to develop vision-based systems that can be used to evaluate road signing and lining that has become defective due to damage and/or wear and tear. Such a system could enable the automatic detection of defects and could provide objective performance parameters for these important road safety features. The system has the potential for reducing risk to contractors working on the road as well as increasing the safety of road users. It would also reduce the costs associated with maintaining the highway by eliminating time-consuming manual assessment.
