In which exhibit can you find typical cycle lengths?

• A. Exhibit 19-7
• B. Exhibit 12-3
• C. Exhibit 15-6
• D. Exhibit 20-1

Answer: (A)

Typical cycle lengths can be found in Exhibit 19-7, which typically contains data regarding signal timing and traffic operations. This exhibit is part of resources focused on traffic engineering and signalized intersections, providing valuable information to civil engineers and transportation planners regarding design and operational standards.

Cycle lengths refer to the total time it takes for a complete sequence of signal phases at an intersection. Understanding typical cycle lengths is crucial for optimizing traffic flow, ensuring efficient signal operation, and enhancing roadway safety. This type of information aids traffic engineers in determining optimal signal timings, which are essential for managing intersections effectively.

The other exhibits mentioned may contain relevant transportation data but are not specifically focused on typical cycle lengths, making Exhibit 19-7 the correct reference for this information.
