Which analysis method is commonly used for evaluating traffic signal performance?

The Highway Capacity Manual (HCM) methodologies are widely recognized and used for evaluating traffic signal performance. The HCM provides standardized procedures and tools to analyze traffic flow at intersections, including those controlled by traffic signals. It offers criteria for assessing the operation of traffic signals, such as delay, levels of service, and queuing, which are essential for understanding how well a signal is performing in terms of optimizing traffic movement and minimizing congestion.

The methodologies outlined in the HCM take into consideration various factors that influence traffic signal operations and provide the means to conduct detailed analyses, ensuring that traffic signals are functioning efficiently to meet the demands of moving vehicles and pedestrians. The HCM's approach also allows for the benchmarking of different signal designs and configurations, providing vital information that can be used in planning and operational decision-making.

Other options focus on different aspects of transportation engineering, which may not be specifically tailored for analyzing traffic signal performance.
