Performance metrics

Performance metrics are designed to measure the Chicago Transit Authority’s success in meeting its goal of providing on-time, clean, safe, efficient and courteous service.

Transit Asset Management

Transit Asset Management (TAM) is a business model that prioritizes resources based on asset conditions and performance to provide safe, cost-effective, and reliable public transportation. TAM is also the subject of a set of new federal regulations and reporting requirements with which CTA must comply beginning in October 2018. Beyond ensuring compliance with federal requirements, the goal of the TAM Plan is to improve the quality of information available to optimize the allocation of maintenance and capital planning & investment resources.
