"In its eighth year of publication, the Safety Management Information Statistics (SAMIS) Annual Report continues to provide uniformly collected comprehensive safety and security data. These data are collected from all recipients or beneficiaries of Urbanized Area Formula funds through the National Transit Database (NTD) Reporting System. Additions to this year's report include a thematic map of states' relative transit collision rates, a series of graphs analyzing grade-crossing collisions, a reorganization of the security data tables, and safety and security information for Purchased Transportation. Purchased Transportation consists of public transit agencies or private carriers who provide public mass transportation services under contract to recipients of Urbanized Area Formula funds."
