Smartphone Based Traffic Sign Inventory and Assessment
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 smartphone based road inspection system. The system was tested in Cranberry Township, Pittsburgh, with the help of their maintenance department. They collected the road data with the collection system. The authors analyzed the data to find all the stop signs and determine any problems with it. The result was compared with a stop-sign inventory established independently from the system.
