Mashup Up Traveler Information Data to Tell a Story
Iowa DOT uses mashup data on the map (e.g., construction, winter) to help tell a traffic story so users can make better decisions.
Traveler Information Icon Color Change Based on Work Zone Data Exchange (WZDx)
Iowa DOT uses connected arrow boards to automatically report when lane closures are in effect in work zones (which is also an indication when workers are present). The connected arrow board indication is used to update the WZDx feed and Iowa DOT’S traveler information system which uses this information to update the icon color that is displayed on the Iowa DOT 511 website based on if the connected arrow board is on or off. There is a verified checkmark when the connected arrow board is turned on.
Iowa Counties’ Road Notifications Added as a Layer on the Iowa DOT 511 Website
In June 2024, a request from the Governor of Iowa via the Iowa DOT Executive Director was issued to find a way to display county road closures on the DOT 511 Site. The County Engineers Service Bureau already provide an Iowa 511 County Map. The information from the Iowa 511 County Map was launched as a new layer on the Iowa DOT 511 website on July 1 and on the mobile app July 9 with implementation from the Iowa’s traveler information consultant.
