Hundreds of thousands of miles of roadways in Arizona and a number of other states are part of a growing network of images detailing guardrails, street-signage, striping and other features central to understanding and improving highway safety.
Mapillary, a hosting platform for street-level imagery, has some 40 million images from 270,000 miles of roadways from state transportation departments in Utah, Florida, Arizona, Connecticut and Vermont. The images have been processed with “computer vision” to identify key items like signage and striping. The data is used by DOTs to examine any given stretch of highway for safety, suitability and other criteria.
