SAM Data Quality Programme 2026
Procurement Image
In 2026, SAM is launching a data quality programme to improve the accuracy, consistency, and long-term value of the data flowing into our systems. As transport services become more integrated and increasingly data-driven, clear standards and reliable information are essential to support effective decision-making, meaningful insights, and better outcomes for passengers, operators, and local authorities. The programme brings together standards, guidance and system changes designed to ensure data submitted to SAM is robust, comparable and fit for future use.
One of the key elements: the move to the LocDef211 national standard for bus stop identification. It sets out why adopting LocDef211 is critical to reducing errors, improving consistency and enabling better analysis across datasets, supporting our broader ambition to raise data quality across the network.
