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. E.g. if a driver is not able to see a stop sign, he
or she might drive into an intersection without stopping and cause an accident.
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 we developed a traffic sign inventory and assessment system that built on our
smartphone based road inspection system.
