It provides examples of traffic control setups and discusses safety practices suggested for these operations. Ñ Highway Agency Staff will find this Handbook helpful in assessing mobile … NOTE: Users of this Handbook should be aware that changes to the provisions in this Handbook may occur as a result of the Final Rule on Proposed Revision 2 of the Manual on Uniform Traffic Control Devices (MUTCD). The Final Rule on Proposed Revision 2 is expected to be published late in 2003. This Handbook is intended for use by a wide range of highway practitioners. It emphasizes that adequate advance planning and time to set up and remove good temporary traffic control is essential to ensure the safety of workers and road users

8. Where parked vehicles and other daytime conditions restrict access to the roadway for sweeping and other pavement operations, working at night may provide the needed roadway access without major disruption to daytime traffic patterns. 9. On highways with narrow median shoulders, safe daytime access to the median to remove debris and repair or replace traffic control devices often requires a full lane closure resulting in major traffic congestion. These operations can often be conducted as a mobile operation at night when traffic volumes are low, with minimal impact on traffic flow. Typical Mobile Night Operations- These operations are carried out routinely in some highway agencies, while other agencies restrict mobile night operations, or all night operations, to emergency responses, or to major construction projects. Highway work often carried out as mobile night operations include the following: • • • • • Pavement marking installation – new markings and restriping. Longitudinal markings are most common, but intersection and special markings are also done at night. • • • • • Pavement marking removal – to revise traffic patterns or prepare pavement for new markings. • • • • • Raised pavement markers – new installations and lens re- placement. • • • • • Shoulder rumble strips – installation. • • • • • Pavement sweeping – where parked vehicles or traffic limits daytime access. • • • • • Pavement sampling – coring, pavement soundings, skid tests, etc. • • • • • Pavement repairs – limited in scope, such as pothole patching and other small repairs. • • • • • Debris cleanup – both routine cleanup and removal of debris, and emergency removal of storm debris and spilled material. • • • • • Vegetation control – application of herbicides adjacent to shoulders. • • • • • Traffic signal repairs – routine lamp replacement and emergency repairs. • • • • • Post mounted delineators – repair, replacement, installation. • • • • • Small roadside signs – repair, replacement, installation. • • • • • Cleaning drainage facilities – catch basins, drop inlets, etc. • • • • • Emergency repairs – miscellaneous operation necessary to restore safe highway operation that can be completed within a few minutes. Operations requiring longer exposure of work crews should use stationary traffic control setups. • • • • • Incident management – Unplanned incidents may require the setup of detours, road closures, diversions, etc. to control traffic through or around the incident area. While the established traffic controls may need to remain in place for an extended period, the operation to set them up may be handled as a mobile operation during night hours. Likewise, planned incidents such as movement of oversize loads may occur at night, and fall into the category of mobile operations…..
