The TTCP legend should include which of the following elements?

• A. Device types, placement, spacing, timing, sequence
• B. Weather forecast
• C. Vehicle models
• D. Contractor names

Answer: (A)

The legend in a TTCP communicates how to read the plan by stating what each symbol and abbreviation means, so everyone on site interprets the setup the same way. It should specify the types of traffic control devices used (cones, barrels, barriers, signs, etc.), where those devices are placed, how far apart they should be spaced, how long they stay in place (timing), and the order in which they’re deployed or removed (sequence). This clarity is essential for creating a safe, orderly work zone and for coordinating how traffic is diverted or narrowed as work progresses. Weather forecast, vehicle models, and contractor names aren’t part of the TTCP legend. Weather notes may influence planning elsewhere, but they don’t define the standardized meanings of plan symbols. Vehicle models and contractor names aren’t relevant to understanding the traffic control layout either.
