• Abstract:
  An analyst can integrate DDSA into an ICE with a few basic steps. This guide presented an overview of ICE and an example to compare intersection designs and address safety concerns. In this example, a roundabout was recommended as the preferred alternative. The analysis shows that the roundabout will provide a greater reduction in fatal and injury crashes while having similar operational characteristics as the other alternatives. The benefit-cost analysis found that the benefits exceed the costs for the recommended alternative, demonstrating that it is a sound safety investment that is one step closer to realizing the goal of zero deaths and serious injuries on the Nation’s roadways.
