Abstract:This report describes the methodology and results of analyses performed to identify and evaluate
alternative methods to control traffic entering a lane closure on a two-lane, two-way road from low-volume
access points. Researchers documented the state-of-the-practice regarding temporary traffic control at lane
closures on two-lane, two-way roads in Texas, and examined existing and innovative devices and strategies
that could be used to control traffic entering from low-volume access points. Researchers also compared the
benefits and costs of various temporary traffic control alternatives for low-volume access points. Motorist
surveys and field studies were conducted to assess motorist understanding and the operational and safety
effectiveness of two innovative devices to control traffic at low-volume access points. The findings from
these tasks and studies were used to develop guidelines regarding the appropriate traffic control for low-volume access points within a lane closure on a two-lane, two-way road.
