  1. Improving Highway Safety Iowa’s Efforts to Reduce Fatal and Serious Injury Crashes Jeremey Vortherms, PE State Transportation Safety Engineer July 17-18,2013

  2. Creating a More Effective Safety Program • Use all the funding • Evaluate the project selection strategy • Emphasize low cost solutions

  3. Using HSIP Funds • Obligations have increased • Partner with 3R and 4R programs • Maintain the intent of the HSIP program

  4. Evaluate the Project Selection Strategy

  5. Evaluate the Project Selection Strategy Some questions about your project selection you should consider: • Are you investing in high cost, spot locations or corridors? • Is your spending so dispersed that feels difficult to accomplish goals? • Are you getting to a few miles or to many? Could you get to more? • Which safety features have had the greatest positive impact to the most highway users? • Are your solutions & countermeasures matched to your greatest problems? • Are there opportunities to partner with other programs, jurisdictions? Can you extend a 3R project? Can you do more than usual in a safety project? • Are you balanced in your approach – segment only, intersection only, blended?

  6. Evaluate the Project Selection Strategy “If it’s good enough to be a policy, it is perfect to be in a safety project.”
