The Vulnerable Road User Safety Assessment is an assessment of the safety performance of the state of Iowa with respect to vulnerable road users and the plan of the state of Iowa to improve the safety of vulnerable road users. It is required by law and is described under 23 U.S.C. 148(1).
The assessment is driven by demographic and performance-related data developed in consultation with local governments that represent high-risk areas. This assessment is used to identify areas of high risk to vulnerable road users, and then utilize that assessment to drive strategy and investment decisions around further safety improvements to mitigate identified safety risks.

responsibility to maintain. Each maintenance garage is displayed in a different color to show where one area of responsibility ends and another begins. Updated August 2016. All primary roads that Iowa DOT maintains color-coded by Maintenance Garage.This provides the previous years overview and crash\ndashboards back to 2018 (the crash dashboard was slightly different in\n2018). If users want to go back to\nprevious years to determine the performance of a work zone they can use these\ndashboards.
