• Abstract:
  The Tennessee Department of Transportation (TDOT) Traffic Design Manual provides information on Traffic Signal Design, Signing and Pavement Markings, Roadway Lighting and Intelligent Transportation Systems. While the chapters on Signing and Pavement Markings, as well as the chapter on Roadway Lighting, have been recently revised, the Traffic Signal Design chapters did not specifically reflect the standards of the 2009 Manual on Uniform Traffic Control Devices (MUTCD) and current signal timing guidelines. The subject manual also lacked the provision of relevant information regarding Traffic Signal Inspection Guidelines and Traffic Signal Maintenance Guidelines. Furthermore, the chapter on Intelligent Transportation Systems (ITS) has been partially revised, but still lacks additional information on Systems Engineering Analysis, Project Stage Diagram and Device Procurement. Since TDOT does not maintain traffic signals, it is very important for TDOT to make current and detailed documentation available to agency designers, consultants and city/county administrators to provide better operations and maintenance of traffic signal control devices. The manual update, provided to the Traffic Operations Division at TDOT, consists of a comprehensive review of available standards and guidelines related to the design, operation and maintenance of traffic signals. In addition to that, the proposed revision of the ITS chapter provides agencies with relevant and consistent information on policies, guidelines and standard procedures related to Intelligent Transportation Systems, Systems Engineering Analysis templates, Project Stage Diagrams and Device Procurement. The project also updated TDOT 730 Traffic Signals Specifications.
