An Assessment of Safety and Geometric Design Criteria for Diverging Diamond Interchanges NCSU has recently invested in a FORUM8 Driving Simulator along with VR-Design Studio DS (formerly UC-win/Road DS) as part of this Transport Research Board funded project. The aim of the project is to investigate certain features of driver behaviour when confronted by a Diverging Diamond Interchange.

Chris Cunningham, the Director of the Highway Systems Group at the Institute for Transportation Research and Education at NCSU commented “We are going to use the FORUM8 driving simulator to look at various unique geometric design components of these Diverging Diamond Interchanges, such as the crossover design and the right and left turn movements at the off ramp, we believe that this is where drivers must look down an approach which may not be intuitive.”
