Abstract:

Researchers at the Texas Transportation Institute (TTI) and at the Center for Transportation Research (CTR) have developed recommendations to help establish and maintain complex work zones to reduce motorist confusion and make it easier to maneuver through the activity areas. Researchers employed test subject drivers to drive through a sample of complex work zones. This process was used to identify specific work zone features and driving situations that create motorist confusion and anxiety about the proper travel path through the work zone. With an improved understanding of the features and conditions that contribute to driving difficulties in these complex work zones, researchers next focused on determining why these features and conditions occur and on what can be done to eliminate them.
