Work zone safety is paramount to state departments of transportation for the traveling public and work crews. Temporary traffic control procedures can help ensure safe and effective operations under a variety of work conditions, especially for mobile operations on two-lane roadways. However, poor driver behaviors around mobile operations are a major concern to workers. Behaviors include distracted and impaired driving, excessive speeds, tailgating of the work vehicles, and rear-end collisions with truck-mounted attenuator vehicles or with other vehicles already queued behind the work activity. 

Under NCHRP Project 03-132, The Texas A&M Transportation Institute was asked to develop guidelines to enhance the safety and effectiveness of mobile operations on two-lane, two-way roadways under variable conditions.

In addition to the final report published as NCHRP Web-Only 354, a guidelines document and presentation of research results is available at https://doi.org/10.17226/26893.
