The research team recently won a competitive FHWA project to evaluate dynamic speed feed back signs on rural roadway curves to determine how effective they are in reducing speeds and crashes. The FHWA project is funded at $300,000 and requires a 100% match. As presented to the IHRB board at the June 2007, this proposal to IHRB will provide partial match. Other sources of match include the Iowa DOT Office of Traffic and Safety, the Midwest Transportation Consortium (MTC), and the Texas Department of Transportation
