CC Cable Car Streetcar type of passenger vehicles operating by means of an attachment to a moving cable located below the

CR Commuter rail A transit mode that is an electric or diesel propelled railway for urban passenger train service consisting of local short distance travel operating between a central city and adjacent suburbs. Service must be operated on a regular basis by or under contract with a transit operatorfor the purpose of transporting passengers within urbanized areas, or between urbanized areas and outlying areas. Such rail service, using either locomotive hauled or self propelled railroad passenger cars, is generally characterized by multi-trip tickets, specific station to station fares, railroad employment practices and usually only 1 or 2 stations in the central business district. It does not include heavy rail rapid transit or light rail/street car transit service. Inter city rail service is excluded, except for that portion of such service that is operated by or under contract with a public transit agency for predominantly commuter services. Predominantly commuter services means that for any given trip segment (i.e., distance between any 2 stations), more than 50% of the average daily ridership travels on the train at least 3 times a week.
Only the predominantly commuter service portion of an inter city route is eligible for inclusion when determining commuter rail route miles.

DR Demand response A transit mode comprised of passenger cars, vans or class C buses operating in response to calls from passengers or
their agents to the transit operator, who then dispatches a vehicle to pick up the passengers and transport them to
their destinations. A demand response operation is characterized by the following: a) the vehicles do not
operate over a fixed route or on a fixed schedule except, perhaps, on a temporary basis to satisfy a special need; and, b) typically, the vehicle may be dispatched to pick up several passengers at different pick-up points before taking them to their respective destinations and may even be interrupted en route to these destinations to pick up other passengers. The following types of operations fall under the above definitions provided they are not on a scheduled fixed route basis: many origins many destinations, many origins 1 destination, 1 origin many
destinations and 1 origin 1 destination.
