What is the most common TTC finding?

Device spacing and taper lengths that do not match the design speed, and pedestrian routes that disappear between phases.

Do signalized intersections need separate TTC review?

Yes — signal work, detection, and pedestrian signals each need a maintained condition through every phase.

Plan Review Checklists

Temporary Traffic Control (MOT) Plan Review Checklist

Short answer

Reviewing temporary traffic control plans means checking that each phase keeps traffic and workers separated — correct taper lengths, device spacing, buffer zones, and pedestrian routes — and that the right Standard Plans 102-series indexes are cited for each operation.

Maintenance of traffic plans protect workers and the traveling public at the same time — they are drawn to be safe under speed, volume, and phase conditions that change daily on site. The review is about conformance to MUTCD and the 102-series Standard Plans, plus whether the phasing sequence actually works.

Most TTC findings are geometric (tapers and spacings that do not fit the posted speed) or sequencing failures (a phase that leaves no pedestrian path).

What a review of traffic control plans checks

Every construction phase has a TTC layout — nothing is left to "field adjust".
Taper lengths and buffer spaces are correct for the posted design speed.
Channelizing device spacing matches the 102-series requirements for the condition.
Pedestrian and bicycle routes are maintained or detoured through every phase.
Temporary barrier and end treatments cited to the correct 102-series indexes.
Advance warning sign sequences complete and correctly spaced.
MOT notes cover night work, drop-offs, and driveway/business access.
Phasing narrative and the phase plans are consistent with each other.

The 102 series is the vocabulary

FDOT’s 102 series indexes define the standard TTC layouts — lane closures, shoulder work, barrier installations, pedestrian detours. Citing them imports requirements the plans must then satisfy: each index’s SPI lists what the plans must show, and the library on this site carries those requirements per index.

Phasing is the hard part

Individual phase sheets can each be compliant while the sequence between them fails — a phase that paves over the only detour lane, or closes the pedestrian path the previous phase established. Review the sequence as a movie, not as stills.
