Field Review
After determining what signs are needed and approximately
where they should be located based on the (TMUTCD),
traffic engineers conduct a field review to refine sign locations.
Most of the field work required for plan preparation is to:
- determine estimated roadside sign post lengths for large guide signs
- determine overhead sign support spans, tower heights and drill shaft foundations, and
- determine any site restrictions and document existing or proposed conditions that could affect sign visibility.
