What does 'positive protection' mean in work zone traffic control?
Answer: Using concrete barriers or other rigid devices to physically separate workers from live traffic
Positive protection means using physical barriers such as temporary concrete barrier (TCB) to prevent errant vehicles from entering the work area, protecting workers from traffic hazards.
What is the required inspection frequency for a temporary traffic control setup on an active FDOT project?
Answer: Daily inspection by the inspector and documented on the daily work report
The inspector must document a daily inspection of all traffic control devices to verify compliance with the approved MOT plan, noting any deficiencies and required corrections.
What is a 'temporary traffic signal' used for in a work zone?
Answer: To coordinate alternating one-way traffic flow through a single-lane section
Temporary traffic signals coordinate alternating one-way traffic flow through sections where only one lane is available, such as bridge rehabilitation or single-lane rural road work.
What are 'drums' or 'channelizing devices' used for in a work zone?
Answer: To delineate the edge of the travel lane and guide traffic through the work zone
Drums and channelizing devices are high-visibility orange delineators placed along the edge of the travel lane to guide drivers through lane shifts, tapers, and channelized paths in the work zone.
What must an inspector do when traffic control devices are found to be missing or non-compliant during a nighttime inspection?
Answer: Require the contractor to correct deficiencies immediately or shut down work until corrections are made
Missing or non-compliant traffic control devices pose an immediate safety risk; the contractor must correct deficiencies immediately, and if unable to do so, work must stop until compliant conditions are restored.
What is the 'activity area' in a work zone traffic control plan?
Answer: The portion of the work zone where construction activities actually take place, including the work space and buffer space
The activity area is the section of the work zone that contains the actual construction operations, including the work space where workers are active and the buffer space between traffic and workers.
