What type of plans are indicated by a sheet number prefix of T?

The type of plans indicated by a sheet number prefix of T refers specifically to Traffic design plans. Plans are categorized with specific prefixes to streamline project organization and ensure clarity in documentation. The “T” prefix uniquely designates traffic-related designs, which can encompass signalization along with other traffic management features.

Given that traffic design plans encompass features such as traffic signals, signage, and roadway markings, they play a critical role in the overall traffic flow and safety of roadway systems. This makes the identification of these plans essential for understanding their purpose and for effective planning and implementation in engineering projects.
