Abstract:

Road signs are an important part of the infrastructure and are needed to ensure smooth and safe traffic flow. Faded, occluded, damaged or vandalized signs can confuse or misinform drivers and lead to unsafe driving behavior. Government agencies are tasked with maintaining good signage and part of it is regular inspections to detect problems. Current methods involve manual inspections, specialized vehicles, or citizen reports. They are tedious, expensive, or not always reliable. In this project the authors developed a traffic sign inventory and assessment system that built on a previously developed smartphone-based road inspection system. In the first version of the system the authors automatically detected road distress by using computer vision algorithms to find road cracks in the images. In this second version the authors extended it to detect road signs, specifically stop signs.
