Van
A 20-foot long or shorter vehicle, usually with an automotive-type engine and limited seating that normally is entered directionally through side or rear doors rather than from a central aisle, used for demand-responsive, vanpool and lightly patronized motor bus service. Also a vehicle having a typical seating capacity of five to 15 passengers and classified as a van by the vehicle manufacturer. A modified van is a standard van which has undergone some structural changes, usually made to increase its size and particularly its height. The seating capacity of modified vans is approximately nine to 18 passengers. Modified vans also may be referred to as "cutaway vans."

Vanpool
A voluntary commuter ridesharing arrangement, using vans with a seating capacity greater than seven persons (including the driver) or buses, which provides transportation to a group of people traveling directly from their homes (or a pre-arranged meeting place, such as a park-and-ride lot) to their regular places of work within the same geographical area, and in which the commuter/driver does not receive compensation beyond reimbursement for his or her costs of providing the service. Also an arrangement in which a group of passengers share the use and cost of a van in traveling to and from pre-arranged destinations together. Generally, carpooling agreements are not arranged by contract, whereas vanpool and buspool agreements are contractually binding.

Variable cost
A cost that varies in relation to the level of operational activity.

Variety of Transportation Choices
Transportation choice means providing residents with multiple, safe and connected options- driving, rail and bus transit, bicycling, walking - to get from one place to the other. Providing choice ultimately enables regions and communities to move toward a less congested transportation system and cleaner air.

Vehicle maintenance
All activities associated with revenue and non-revenue (service) vehicle maintenance, including administration, inspection and maintenance and servicing (cleaning, fueling, etc.) vehicles. In addition, it includes repairs due to vandalism and accident repairs of revenue vehicles.

Vehicle miles
The total number of miles traveled by transit vehicles. Commuter rail, heavy rail and light rail report individual car miles rather than train miles for vehicle miles.

Vehicle miles of travel (VMT)
The number of miles traveled within a specific geographic location by vehicles for a period of one year. VMT is calculated either by using two odometer readings or, in the absence of one of the odometer readings, by regression estimate.

Vehicle miles operated
Sum of all miles operated by passenger transit vehicles, including mileage when no passengers are carried. When vehicles are operated in trains, each vehicle is counted separately (e.g., an eight-vehicle train operating for one mile equals eight vehicle miles).

Vehicle operations
All activities associated with the subcategories of the vehicle operations function: transportation administration and support; revenue vehicle operation; ticketing and fare collection; and system security.

Vehicle revenue miles/hours
The miles/hours a vehicle travels while in revenue service. Vehicle revenue miles/hours exclude travel to and from storage facilities, training operators prior to revenue service, road tests and deadhead travel, as well as school bus and charter services.

Vehicle trip
A trip by a single vehicle regardless of the number of people in the vehicle.

Vehicles available for maximum service
The number of revenue vehicles available to meet annual maximum service requirements. This includes spares, out-of-service vehicles and vehicles in or awaiting maintenance, but excludes vehicles awaiting sale and emergency contingency vehicles.

Vehicles in total fleet
All revenue vehicles held at the end of the fiscal year, including those in storage, emergency contingency and awaiting sale.

Vehicles operated in maximum service
The number of revenue vehicles operated to meet annual maximum service requirements. This is the revenue vehicle count during the peak season of the year, on the week and day that maximum service is provided. Vehicles operated in maximum service exclude atypical days or one-time special events.

Virtual office
A type of telecommute in which workers are equipped with the tools, technology and skills to perform their jobs from anywhere the person has to be -- home, office or customer's location. Also known as a "mobile office."

VOC
Volatile Organic Compound. See "fossil fuel."
