Traffic Signal Design Manual
This manual establishes uniform procedures for the design preparation of traffic signal plans and installation in the City of Redmond. It is not intended as a textbook or as a substitute for solid working knowledge, experience, and judgment of the principles of traffic signal design, but rather as a guideline to uniformity and to provide the designer with sufficient information to prepare the desired plans with a minimum of uncertainty.
There are three "types" of documents.
1. Traffic Signal Design Manual - This is the manual itself, it includes guidelines for general traffic signal design requirements, typical process for installation of a traffic signal, City's signal plans format preferences, and City's signal design requirements.
2. Redmond Special Provisions to the Standard Specifications
3. Sample Plans
