Practices in One-Lane Traffic Control on a Two-Lane Rural Highway
Temporary traffic control (TTC), also known as maintenance of traffic, is critical to minimizing congestion and maintaining mobility during planned and unplanned activities as well as providing a safe work zone for both road users and workers. This synthesis identifies innovative practices and devices for establishing one-lane traffic control on rural two-lane highways. Specifically, this synthesis sought to identify practices and lessons learned in many areas, including construction versus maintenance activities, day and nighttime operations, length of lane closures, delay and other operational impacts, treatments for side roads and driveways, corridor management of work zones, and innovative devices used to support one-lane two-way (1L2W) operations. A literature review and detailed survey responses from 45 departments of transportation (DOTs) are presented. Survey questionnaire results indicated that human flagger control is the most common traffic control method utilized in 1L2W operations. Other findings show that pilot cars and temporary traffic control signals (TTCSs) are frequently used by state DOTs. Over 66% of the reporting state DOTs use design criteria such as maximum length of closure, maximum traffic volumes, maximum target vehicle delays, and maximum speed limit for selecting the traffic control method in 1L2W operations. State DOTs frequently use a combination of self-managed control, flagger, and TTCSs to control traffic on side roads within a single-lane TTC zone.
