Temporary Traffic Control Permits

The safe and reasonable flow of pedestrian traffic should always be maintained. If an existing pedestrian facility is impacted by a short-term or short-duration work area, establishing and alternative pedestrian route may not be necessary if the work can be halted and pedestrians can continue to use the existing pedestrian facility in a safe manner. This shall be determined by Temporary Traffic Control (TTC) staff.

If a pedestrian facility must be intermittently closed due to conflict with construction activities, pedestrian spotter(s) shall be deployed at the work area for the entire duration of time the closure is in place. Pedestrians may be delayed for short periods of time for project personnel to remove obstructions or overhead hazards to ensure safe passage.

Pedestrian spotters’ sole duties shall be monitoring for pedestrians, alerting project personnel of approaching pedestrians, and provide assistance to pedestrians with disabilities as needed. The spotter shall always stay focused on these duties and avoid distractions (no use of cell phones, headphones, etc.). At no time shall pedestrian spotters redirect or escort pedestrians away from the existing pedestrian facility. Spotters shall always wear high visibility apparel. Flaggers or off-duty officers may be used as pedestrian spotters but are not required.

Additional warning signs and/or ADA compliant channelizing devices may be used with pedestrian spotters to support safe passage of the pedestrian facility through the work area. A Temporary Pedestrian Access Plan (TPAP) may be required by TTC Staff for review.

Automated Flagger Assistance Device (AFAD) operations must abide by the standards set forth in the MUTCD Sections 6E.04‐06. AFADs are remotely operated traffic control devices enabling flaggers to be positioned out of the traffic lane(s) and are used to control traffic in advance and within work zones.

These devices are designed to be remotely operated. AFAD configurations using stop/slow or red/yellow lens applications are permitted in Mesa. AFAD operators shall be flagger certified in accordance with Section 5.2 of the Mesa Temporary Traffic Control Manual. An AFAD shall be remotely operated by an operator who is trained in the operation of AFADs. The operator shall not leave the AFADs unattended while they are in use. The use of AFADs shall conform to the methods noted in the MUTCD Section 6E.04.

Additionally, a single AFAD operator may operate more than two AFAD devices as approved by TTC Staff and/or the Mesa Traffic Engineer. AFADs can be used on local and collector roadways with a single lane of traffic per direction, posted speed of 35 MPH or less, and where traffic volumes do not exceed 5,000 vehicles a day. AFADs should be placed along the shoulder section of the roadway and not in conflict with traffic or traffic control devices such as traffic signals or pedestrian hybrid beacons. Maximum spacing between devices should not exceed 800 feet. A fail‐safe plan addressing malfunction of an AFAD must be in place and submitted to Temporary Traffic Control Staff prior to permit approval.
