It's one of those things that you've always thought was true, but now we have proof. Ohio roads are terrible. According to lvl5, a group working in the self-driving cars field, after logging 5,000,000 plus miles of road, Ohio has the fourth worst roads in the country. Michigan, Iowa and Indiana roads are worse and it's no surprise that Florida and Hawaii are the best in the country. Here's what went into the study, according to Medium.com:
The country-wide dataset spans over five million miles of Payver driving data from the last year. The methodology for ranking these videos included randomly selecting video frames from the videos (in total, 15 million frames sampled), and excluding all but the surface of the road from predictions by a neural network. Their neural network measures quality in four distinct areas: road paint fading, pavement cracking, potholes, and surface flatness. The data was normalized by frame density, and filtered to remove areas with not enough data.
So next time you feel that thud when you're driving, don't worry, you're not crazy, the roads really are that bad.
