transit asset management, asset criticality, MAP-21


All transit agencies are required to make decisions about their assets. Decisions range from long-term strategic decisions, such as capital replacements or extensions, to short-term operational decisions, such as prioritizing unplanned maintenance or taking an asset out of service. Determining the criticality of its assets can help an agency understand their relative importance, thereby helping prioritize decisions and work activities more effectively and consistently.
