Development of Guidelines for Nighttime Road Work to Improve Safety and Operations

Work zones pose safety problems for both motorists and workers. While work zones result in significant amounts of congestion and associated delay, lead to accidents and related losses, cause adverse impacts on communities and business, and increase driver frustration, the need to construct new highway facilities, preserve existing roadways, and perform maintenance make work zones unavoidable. Growth in traffic volume has led many agencies to defer road work activities to off-peak hours to avoid congestion. Nighttime work, however, raises additional safety problems. Some guidance and minimum requirements for dealing with these situations are provided in the Manual on Uniform Traffic Control Devices (MUTCD), but these are not considered sufficient for the planning, design, implementation, and operation of road work at night. Project 17-17 developed guidelines for nighttime road work to improve safety and operations and also developed procedures to facilitate making decisions about undertaking nighttime work. The objectives of this project are to (a) enhance the guidelines for nighttime road work to improve safety and operations, (b) conduct additional case studies to verify the applicability and demonstrate the flexibility of the procedures, and (c) develop a fully self-contained training package to introduce the Procedures and Guidelines.
