• If these requirements cannot be physically implemented, then MUTCD PART 6 TEMPORARY TRAFFIC CONTROL standards shall apply as the minimum. The traffic control plans are to be used along with sound judgment. Proper planning, a good safety conscious attitude and full participation from the persons involved in the work zone are all prerequisites to good traffic control. Aspects of the roadway environment such as weather, time of day, traffic volumes, traffic speed, roadway geometry, roadside conditions, and your inventory of traffic control devices should all be considered when implementing the guidelines.

• Work Description:

• Work Schedule (days, hours)

• Night Operations?

• Night Operations Lighting Plan and temporary illumination equipment (except in emergency situations) conforming to the NCHRP Report 476, titled “Guidelines for Design and Operation of Nighttime Traffic Control for Highway Maintenance and Construction” (Bryden and Mace, 2002b) shall be used to illuminate all traffic control stations.
  

• Work Duration

  Select Long-term Stationary (3+ days) Intermediate-term Stationary (1-3 days) Short-term Stationary (1+ hrs/single daylight period or 1+ hrs night) Short Duration (Up to 1hr) Mobil Operation (Intermitent/Continuous) Emergency Situation (Unplanned Only)

  • Long-term Stationary (3+ days)
  • Intermediate-term Stationary (1-3 days)
  • Short-term Stationary (1+ hrs/single daylight period or 1+ hrs night)
  • Short Duration (Up to 1hr)
  • Mobil Operation (Intermitent/Continuous)
  • Emergency Situation (Unplanned Only)

• When the flagger is moving with the operation, all signs associated with the flagger shall be moved ahead whenever the work advances more than two (2) miles from the first advanced warning signs. The 'Flagger Ahead' sign must be within 1500ft of the flagger and the flagger must be seen from the sign. At no time can it be closer then as described in the sign spacing chart.

• Considering the safety issues inherent to night work, consideration should be given to enhancing traffic controls to provide added visibility and driver guidance, and increased protection for workers, work vehicles, equipment and stationing uniformed law enforcement officers and lighted patrol cars at night work locations where there is a concern that high speeds or impaired drivers might result in undue risks for workers or other drivers.

• Short-term closures may be allowed without advanced public notification for emergencies or off-peak closure (night closure). Check with the region traffic office prior to implementing the closure.
  
  Note: Emergency situations are exempt from illumination requirements. For the purpose of this rule, emergency means an unforeseen occurrence endangering life, limb, or property.
  

• Traffic Control Plan

  Typical Application

  Site Specific

• In general, the procedures illustrated represent minimum solutions for the situations depicted. Except for the notes (which are clearly classified using headings as being Standard, Guidance, Option, or Support), the information presented in the typical applications can generally be regarded as Guidance.

• Modifications To Fulfill Special Needs

  Yes

  No

• Approved traffic control plans (TCP) are required for flagging, as with all work zones, and the flagging station must be incorporated into and be an integral part of the TCP. If the approved TCP’s in the M54-44 or other approved plans do not adequately address a specific work zone, the Region Traffic Office should be contacted to assist with developing an acceptable TCP.

• Night Hours: 1/2 Hr before sunset to 1/2 Hr after sunrise
  
  For nighttime flagging, flaggers shall be illuminated by an overhead light source providing a minimum vertical illuminance of 10 fc (108 lux) measured 1 ft (300 mm) out from the flagger’s chest. Lighting systems with flood, spot, or stadium type luminaire(s) shall be a minimum of 10 ft (3 m) above the pavement and shall be aimed downward at the work and rotated outward no greater than 30 degrees from nadir (straight down). Luminaire(s) shall be shielded to minimize glare to approaching traffic and trespass light to adjoining properties.
  
  A supply of emergency flares shall be on-site for use in the event of unanticipated situations such as traffic accidents, equipment breakdowns, failure of lighting equipment, etc. .

  Moderate Volume (~12 vehicles/min/lane)

  High Volume (>20 vehicles/min/lane)

• Work Location

  Select Work Affecting Pedestrian and Bicycle Facilities Work Outside of the Shoulder Work on the Shoulder with No Encroachment Work on the Shoulder with Minor Encroachment Work Within the Median Work Within the Traveled Lane Work Within an Intersection Work in the Vicinity of a Grade Crossing

  • Work Affecting Pedestrian and Bicycle Facilities
  • Work Outside of the Shoulder
  • Work on the Shoulder with No Encroachment
  • Work on the Shoulder with Minor Encroachment
  • Work Within the Median
  • Work Within the Traveled Lane
  • Work Within an Intersection
  • Work in the Vicinity of a Grade Crossing

• When existing pedestrian facilities are disrupted, closed, or relocated in a TTC zone, the temporary facilities shall be detectable and shall include accessibility features consistent with the features present in the existing pedestrian facility.

• For work at an intersection, advance warning signs, devices, and markings should be used on all cross streets, as appropriate. The typical applications depict urban intersections on arterial streets. Where the posted speed limit, the off-peak 85th-percentile speed prior to the work starting, or the anticipated speed exceeds 40 mph, additional warning signs should be used in the advance warning area.

• When paved shoulders having a width of 8 feet or more are closed, at least one advance warning sign shall be used. In addition, channelizing devices shall be used to close the shoulder in advance to delineate the beginning of the work space and direct motor vehicle traffic to remain within the traveled way.

• When work takes up part of a lane, vehicular traffic volumes, vehicle mix (buses, trucks, cars, and bicycles), speed, and capacity should be analyzed to determine whether the affected lane should be closed. Unless the lane encroachment permits a remaining lane width of 10 feet, the lane should be closed.
  
  A lane width of 9 feet may be used for short-term stationary work on low-volume, low-speed roadways when vehicular traffic does not include longer and wider heavy commercial vehicles.

• If work in the median of a divided highway is within 15 feet from the edge of the traveled way for either direction of travel, TTC should be used through the use of advance warning signs and channelizing devices.

• When grade crossings exist either within or in the vicinity of a TTC zone, lane restrictions, flagging, or other operations shall not create conditions where vehicles can be queued across the tracks. If the queuing of vehicles across the tracks cannot be avoided, a uniformed law enforcement officer or flagger shall be provided at the crossing to prevent vehicles from stopping on the tracks, even if automatic warning devices are in place.

• Adjustments in the location of the advance warning signs should be made as needed to accommodate the horizontal or vertical alignment of the roadway, recognizing that the distances shown for sign spacings are minimums. May include Mobile or Rolling Slowdowns where the work and shadow vehicles cannot pull over to allow vehicular traffic to pass frequently, a DO NOT PASS sign may be placed on the rear of the vehicle blocking the lane and shall use high-intensity rotating, flashing, oscillating, or strobe lights.
