Demand Responsive Transport or Demand-Responsive Transit (DRT) or Demand Responsive Service〔(NTD Glossary ) US National Transit Database〕 or Dial-a-Ride Transit (DART)〔(Winnipeg Transit )〕〔(King County Transit )〕 or Flexible Transport Services〔(CONNECT is a Coordination Action in the Sustainable Development Thematic Area of the European Union's 6th Framework Program, successfully ended on December 2005 ).〕 is "an advanced, user-oriented form of public transport characterised by flexible routing and scheduling of small/medium vehicles operating in shared-ride mode between pick-up and drop-off locations according to passengers needs".〔(Synopsis of DRT ) European Commission Directorate-General for Energy and Transport〕 DRT systems typically provide a public transport service for areas of low passenger demand, such as rural areas, where a regular bus service would not be viable.〔〔(www.drtbus.co.uk ) What is DRT?〕 DRT services may also be provided especially for disabled passengers, as with paratransit programs. Ridership on DRT services is usually quite low (less than ten passengers per hour), but DRT can provide coverage effectively.〔(A Guide for Planning and Operating Flexible Public Transportation Services )〕〔(Human Transit: Can a "flexible route" solve the problem of low ridership due to low density? )〕 DRT schemes may be fully or partially funded by the local transit authority, as providers of socially necessary transport. As such, operators of DRT schemes may be selected by public tendering. Other schemes may be partially or fully self-funded as community centred not for profit social enterprises (such as a Community interest company in the UK). DRT schemes may also be provided by private companies for commercial reasons; some conventional bus operating companies have set up DRT-style airport bus services, which compete with larger private hire airport shuttle companies. == Differences from other modes of transport == * Regular transit bus routes: DRT employs flexible routes and schedules〔 * Shuttle bus services: DRT departure and arrival points are not necessarily fixed〔 * Deviated Fixed Route Service: Transit service that operates along a fixed alignment or path at generally fixed times, but may deviate from the route alignment to collect or drop off passengers who have requested the deviation〔 * Paratransit: DRT is available to the general public, whereas paratransit is available to pre-qualified user bases, especially for people with disabilities and the elderly * Share taxis: DRT is pre-booked in advance, whereas share taxis are operated on an ad-hoc basis * Taxicabs: DRT generally carries more people, and passengers may have less control over their journey on the principle of DRT being a shared〔(Demand Responsive Transit service (DRTs):PersonalBus - Tuscany - Florence - Italy ) Report by EU Project Penelope (Promoting ENergy Efficiency to Local Organisations through dissemination Partnerships in Europe) 3 September 2002〕 system as opposed to an exclusive vehicle for hire. Additionally, journeys may divert en route for new bookings.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Demand responsive transport」の詳細全文を読む スポンサード リンク
