Optimizing Work Zone Zipper Merge Operations Using Driving Simulations

The zipper merge concept can reduce time lost in the queue prior to a work zone, driver frustration and accidents that commonly occur when less efficient merging techniques are employed. Even with these benefits, the zipper merge is not always the most ideal merging operation for all scenarios. Travelways with higher speeds, irregular lane setups, large variations in observed traffic speeds, and other situations might not be prime zipper merge candidates. This project will utilize a driving simulator study to help to identify the most appropriate travelway situations for implementing the zipper merge along with the most effective signage and sign packages to help the traveling public properly navigate the closure of lanes prior to a work zone.
