• Abstract:
  The use of temporary median crossovers in work zones allows for the closure of one side of a multi-lane roadway while ; maintaining two-way traffic on the opposite side. This process provides the ability for construction and maintenance crews ; to construct, rebuild, or perform maintenance on a portion of one direction of a roadway segment while allowing roadway ; users continued access through the facility. A number of behavior studies were conducted on single-lane and dual-lane ; crossovers at work zone locations in the State of Nebraska resulting in general guidelines for optimal geometric design ; features of such work zone elements.
