In addition to road maintenance, travel, infrastructure improvements, fighting weather conditions, and monitoring traffic patterns, we believe that empowering people with information about their commute is one of the best ways is one of the best ways to accomplish this.
To that end, ODOT reports current road activity, speeds, incidents, travel delays, closures, and severe weather conditions for all of Ohio’s Highways.
The API allows you to view up-to-date information about ODOT-managed roadways throughout Ohio.
The data we offer is updated up to every minute to provide users with a real time experience.
Who is this for?
Whether its aggregating data from multiple traffic sources, creating traffic prediction models, traffic alert apps or just for fun, the data from ODOT is considered public domain and therefore freely available to anyone.
