A '''Telebus ''', '''Dial-a-bus ''', or '''Dial-a-ride ''' service is a bus service that operates in a mode partway between a normal scheduled bus service and a taxi. The academic name for these services is demand responsive transport. Telebuses typically have a scheduled route, but passengers can ring and book a pick-up within an area served by the route, and the bus route is modified to make the pick-up. Drop offs anywhere within the area can also be accommodated. The aim is to extend public transport services to the front door of all residences, or from any place to any place.
Some services operate exclusively for disabled or elderly passengers; other services are open to the general public.
The term Paratransit has been used as a term for Telebus service. But possibly because paratransit sounds to the uninitiated like a service for the disabled, other terms such as Telebus have become more popular, particularly for services not primarily intended to service disabled passengers. Often paratransit is used to mean Demand responsive transport that is limited to disabled passengers.
