CARS Group 511/traveler information XML data feed access

Welcome to the Condition Acquisition and Reporting System (CARS) Group traveler information XML data feed access portal. This is a service that allows third parties (i.e. commercial traveler information vendors, transportation agencies, researchers, media and others) to access real-time data for use in applications and research efforts.

The highway data feed contains real-time event, closed-circuit camera (CCTV) and traffic speed data, where available, provided by the CARS Group agencies. The agencies providing this data include: Idaho Transportation Department, Indiana Department of Transportation, Iowa Department of Transportation, Kentucky Transportation Cabinet, Louisiana Department of Transportation and Development, Maine Department of Transportation, Minnesota Department of Transportation, New Hampshire Department of Transportation, and the Sacramento Area Council of Governments.

Types of highway data

The data feed includes:
  • All active incidents/accidents
  • Construction
  • Size and weight restrictions for truckers
  • Winter road conditions (where available)
  • Special events also available via 511 websites for each agency, including CCTV information.

Format and update frequency of the 511 highway data feed

The data feed is accessed through a Web connection and in XML format. The feed is updated as individual events become active, are updated or expire and removed from the feed.

How to get access
