What procedure should be followed when benchmarking traffic signal operations?

When benchmarking traffic signal operations, comparing performance metrics against standards is essential. This process involves evaluating the current performance of traffic signals in relation to established benchmarks or standards, which may include factors such as traffic flow, signal timing efficiency, and safety outcomes. This comparative analysis helps technicians and engineers identify areas for improvement, optimize signal operations, and ensure that the traffic signal system is meeting desired performance criteria.

Monitoring these metrics provides insight into how well the traffic signals are functioning and whether they are effectively managing vehicle and pedestrian traffic. It also allows for evidence-based decisions to be made for any necessary changes or upgrades to improve overall traffic management.

The other options do not directly pertain to the benchmarking process. Updating hardware, conducting surveys, or hiring evaluators might be part of broader operational improvement strategies but do not specifically address the act of benchmarking performance against established metrics.
