A Plans Preparation Manual includes information regarding what aspects of traffic signal plans?

The Plans Preparation Manual is a crucial resource in the development of traffic signal plans, as it outlines essential guidelines to ensure that these plans meet the necessary standards. The manual typically specifies the required amount of detail to be included in the traffic signal plans, ensuring that they are comprehensive enough for constructors and other stakeholders to understand and implement effectively.

It also dictates the proper format in which to present this information, allowing for consistency across various projects and making it easier for engineers, contractors, and inspectors to read and interpret the plans. Adhering to the guidelines set in the Plans Preparation Manual helps facilitate a smoother project execution process and enhances communication among all parties involved, essential for the successful deployment and maintenance of traffic signal systems.

The other options, while important aspects of project management and execution, do not specifically pertain to the content and structure of traffic signal plans as outlined within the Plans Preparation Manual.
