How often are CTA performance metrics assessed?

The correct choice highlights that CTA performance metrics are assessed regularly through surveys and statistics. This means that the Chicago Transit Authority employs a systematic approach to evaluate their services by collecting data periodically. This allows them to have a consistent and ongoing understanding of service quality and operational efficiency, ensuring that they can identify trends, measure improvements, and address any areas that require attention more effectively.

By using regular assessments, the CTA can adapt to changing ridership patterns, service demands, and other variables that affect public transit. This continuous evaluation is essential for maintaining high standards and ensuring that transit services meet the needs of the community. It also helps in making data-driven decisions that can lead to improved performance in the long term.
