Design Criteria
AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals, 5th Edition (LTS-5); Structures Manual Volume 9, FDOT Modifications to LTS-5; Structures Manual Introduction, I.6 References. Design Assumptions and Limitations
The maximum span length for the Concrete Poles with Signal Cable is 250 feet. See the PPM, Volume 1, Chapter 29 for more information.
See notes on the Design Standard and Structures Manual Volume 9.
The following computer-based design programs available for use on the Structures Design Office Website:
•FDOT Strain Pole Program
•University of Florida Bridge Software Institute ATLAS Program
For Pole Types P-III through P-VIII, design poles within the following limits:
30 ft. ≤ Length (L) ≤ 65 ft.
Pole Height (H) ≤ 50 ft.
Foundation Depth (D) ≥ 7 ft.
Determine maximum loads to be placed on poles, and select the required pole type meeting the requirements of Table 17725-I and Table 17725-2 below.
