Teen driver studies
Dan McGehee, Michelle Reyes, Cher Carney, Public Policy Center, University of Iowa, December 2012.
This project builds on two successful rural and urban teen driving studies that have been completed in rural Iowa and urban Minneapolis. The study worked with 90 new drivers to evaluate and determine the value in feedback from video triggered events. Feedback was in the form of a "report card" sent to parents along with talking points and other driving information. A control group was used and they received no feedback.
There are a significant number of teenage fatalities each year in Iowa from vehicular crashes. While all states keep and analyze crash records, the amount of detail from each state varies. Specific crash-related factors may not reveal themselves in the overall state-based crash statistics.
The goal of this project is to perform a systematic review of breath alcohol ignition interlock devices (BAIID or IID) to understand how other states have integrated such systems into administrative and judicial practice and to make recommendations for best practices in the state of Iowa.
Projects at Work
This three-minute video highlights the Aurora Program, pooled-fund study SPR-3(042), that Iowa DOT has led since fall 2003. This has been a very beneficial project for the Iowa DOT and its partners.
