Design Services Branch Standards and Tools
Below are standards and tools used in the design of traffic signals and roadway lighting.
For questions or comments, contact Ted Swansegar.
CADD Standards and Traffic Operations Cell Library
The Kentucky Transportation Cabinet uses Microstation Version 8 for all design plans. All plans must comply with the standards set forth by the Division of Highway Design. The links below provide access to these standards and a cell library for use in all traffic signal and roadway lighting plans.
Materials and Estimate Spreadsheets
The Division of Traffic Operations supplies certain materials for traffic signal installations. For accounting and project management purposes, an Install Items List and Release of Warehouse Materials Form shall be provided with all traffic signal plans for projects and permits.  For projects, an estimate spreadsheet shall be provided for traffic signal and lighting plans. Below are downloadable Excel versions of these spreadsheets:

Traffic Signal and Roadway Lighting Standard Detail Sheets
The Division of Traffic Operations has developed Standard Detail Sheets for inclusion in traffic signal and roadway lighting plans. Below are links to the Standard Detail Sheets.  They are listed in the order they are to be inserted into a plan set.​
Sign Details Sheets are made available on this webpage for convenience only.  Any questions regarding the content of these drawings should be directed to the Division of Highway Design.

Steel Strain Pole Analysis (SALSA)


This program calculates the required strengths for steel strain poles, steel mast arm poles, and steel highmast poles based upon the AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, 2013 Edition.

A web application for SALSA is now available.  All users will need to request a login/password.  Please email Ted Swansegar for access.  Prequalification in Electrical Engineering Traffic Signal Services is required to receive access to SALSA.
