To manually download the Structures Manual: Save the PDF files to a computer or server location following the steps below. Note that the executable download version of the Structures Manual is the preferred method of delivery. This manual presumes that a traffic engineering study traffic signal control is needed. This document is intended to provide guidelines for certain considerations involved in the design of such devices. Some of the information contained in this manual reflects departmental policy and State Traffic Commission Regulations as of July 2009. ALDOT traffic signal design elements not addressed by the ITE Manual of Traffic Signal Design include: • Types of signal heads allowed by the ALDOT (e.g., 4-section heads are not 2.0 TRAFFIC SIGNAL DESIGN GUIDELINES 2.1 SIGNAL DESIGN ELEMENTS Any traffic signal proposed for installation on City streets shall meet the minimum criteria as outlined in the on Uniform Traffic Control DevicesManual (MUTCD) and the Alabama Department of Transportation (ALDOT) Traffic Signal Design Guide & Timing , latest Manual editions. ¦ Manual Notice 2019-1 1.

For this reason, standard references for intersection lighting are listed below. 1. Street lighting design should meet or exceed average luminance per the current AASHTO publication, "Roadway Lighting Design site conditions. The structural design of these facilities is addressed in the Bridge Design Manual and Design Manual M 22-01. 17.1.2 Site Reconnaissance General procedures for site reconnaissance are presented in Chapter 2. Prior to the site reconnaissance, the location of the structures should be staked in the field, or an Statewide Traffic Signal Design and Timing Manual. The purpose of the project was to assist the Alabama Department of Transportation (ALDOT) in streamlining the plan preparation and review process, establishing standards for signal design, and providing guidance to designers and maintenance personnel in setting signal timings.
