What is the purpose of a 'Portable Changeable Message Sign (PCMS)' in a construction work zone?
Answer: To provide dynamic messages about work zone conditions, delays, or alternate routes
A PCMS displays variable text messages that can be updated to inform drivers of current work zone conditions, delays, lane closures, or alternate routing.
What is a 'flagger' required to use when controlling traffic in a FDOT work zone?
Answer: A STOP/SLOW paddle, a high-visibility safety vest, and if needed at night, a flashlight or wand light
FDOT flaggers must use a STOP/SLOW paddle, wear a high-visibility safety vest, and use lights (flashlight or wand) when flagging in low-light or nighttime conditions.
What minimum taper length is generally required for a lane closure on a 55 mph roadway?
Answer: 495 feet
Taper length for lane closures is calculated as L = W × S²/60 for speeds ≤45 mph or W × S for higher speeds; on a 55 mph roadway, a typical 12-foot lane requires approximately 660 feet, with FDOT minimums around 495 feet.
What is a 'buffer space' in a traffic control work zone?
Answer: An unoccupied distance between the traffic control devices and the actual work activity, providing recovery space for errant vehicles
The buffer space is an unoccupied area between the last traffic control device and the beginning of the work activity, providing a safety zone that errant vehicles can enter without striking workers.
When must a Maintenance of Traffic (MOT) plan be submitted and approved by FDOT?
Answer: Before any traffic control devices are placed or any lane closures are made
The MOT plan must be reviewed and approved by FDOT before any traffic control devices are placed or lane closures are implemented to ensure proper sequencing and design.
What does a 'road user cost' provision in a construction contract address?
Answer: Financial incentives or disincentives tied to how long a lane or road is closed, compensating road users for delay
Road user cost provisions establish a daily dollar value for each day a lane or road is closed beyond a specified threshold, incentivizing the contractor to minimize traffic disruption.
