Vehicle movements are typically recorded in what that is included in the plans for a traffic signal?

Answer: B — Timing Chart

The correct answer is that vehicle movements are typically recorded in a Timing Chart. A Timing Chart provides a structured overview of how long each movement phase will last for various traffic conditions. It allows traffic engineers to optimize the flow of vehicles and pedestrians through the intersection by specifying the timing for each signal phase, which is critical for maintaining traffic efficiency and safety. A Timing Chart can also integrate information on vehicle movement patterns, including the expected volume during different times of the day, which directly informs how long each signal phase should operate. Recording vehicle movements in this way helps in adjusting signal operations to meet fluctuating traffic demands. While Movement Charts detail the specific vehicle and pedestrian movements at an intersection, they do not typically include timing information. Similarly, a Signal Plan primarily focuses on the layout of the traffic signals and associated infrastructure rather than the timing of signal phases. Tracking Sheets are more oriented towards monitoring and recording ongoing signal performance and adjustments over time, rather than capturing the planned movements and their timings.
