Five Percent Safety Program - Iowa Report

Iowa's 5 Percent Safety Report

Proposed improvements and schedules

In establishing engineering, education, enforcement and emergency response priorities, state agencies consider factors beyond those depicted in this report. For instance, decisions regarding any roadway or intersection improvements are based on detailed engineering studies that consider the strategies most appropriate for site-specific conditions, as well as the cost and anticipated effectiveness of those improvements. Scheduling of these improvements is also contingent upon the availability of highway safety improvement funds.

The following information provides access to specifics regarding Iowa's most severe 5 percent safety needs.
