Which of the following sheets typically includes a detailed layout of traffic patterns?

The correct choice is traffic design standards because this sheet is specifically dedicated to outlining the different traffic patterns and the associated design principles that govern them. Traffic design standards provide guidelines for traffic control devices, lane configurations, intersection designs, and other elements that contribute to the flow of traffic. These standards ensure that traffic patterns are not only efficient but also safe for all road users.

Other sheets like structures plans and signalization plans focus on different aspects of road construction. Structures plans usually deal with the design of bridges, retaining walls, and other structural components, while signalization plans specifically pertain to the placement and operation of traffic signals and related control devices. Roadway plans encompass the overall design of the roadway itself, including alignment, cross-section, and grading, but they may not provide the same level of detail regarding traffic patterns as traffic design standards do.
