DRT can be used to refer to many different types of transport. When taxicab

s were first introduced to many cities, they were hailed as an innovative form of DRT. They are still referred to as DRT in some jurisdictions around the world as their very nature is to take people from point-to-point based on their needs.
More recently, DRT generally refers to a type of public transport. They are distinct from fixed-route services as they do not always operate to a specific timetable or route. While specific operations vary widely, generally a particular area is designated for service by DRT. Once a certain number of people have requested a trip, the most efficient route will then be calculated depending on the origins and destinations of passengers.

Share may refer to:
* Share, to make joint use of a resource (such as food, money, or space); see Sharing

s are another form of DRT. They are usually operated on an ad hoc basis but also do not have fixed routes or times and change their route and frequency depending on demand.
Some DRT systems operate as a service that can deviate from a fixed route. These operate along a fixed alignment or path at specific times but may deviate to collect or drop off passengers who have requested the deviation.

Operation
DRT services are restricted to a defined operating zone, within which journeys must start and finish. Journeys may be completely free form, or following skeleton routes and schedules, varied as required, with users given a specified pick-up point and a time window for collection. Some DRT systems may have defined termini, at one or both ends of a route, such as an urban centre, airport or transport interchange

services, which compete with larger private hire airport shuttle companies.
Health and environmental effects
DRT can potentially reduce the number of vehicles on the road, and hence pollution and congestion, if many people are persuaded to use it instead of private cars or taxis.[
For a model of a hypothetical large-scale demand-responsive public transport system for the Helsinki metropolitan area, simulation results published in 2005 demonstrated that "in an urban area with one million inhabitants, trip aggregation could reduce the health, environmental, and other detrimental impacts of car traffic typically by 50–70%, and if implemented could attract about half of the car passengers, and within a broad operational range would require no public subsidies".
]
Licensing
DRT schemes may require new or amended legislation, or special dispensation, to operate, as they do not meet the traditional licensing model of authorised bus transport providers or licensed taxicab operators. The status has caused controversy between bus and taxi operators when the DRT service picks up passengers without pre-booking, due to the licensing issues. Issues may also arise surrounding tax and fuel subsidy for DRT services.
Effectiveness
Ridership on DRT services is usually quite low (less than ten passengers per hour), but DRT can provide coverage effectively.
List of current DRT systems by country
Since the mid-2010s several DRT projects started up but failed.
In the US several DRT operators appeared and promptly failed, due to either lack of customers or health and safety issues. 2019 trials in London found that "satisfaction was really high"; users scored the service at 4.8/5 and praised ease of use, safety, cleanliness and accessibility. But low take-up, misunderstandings about who the service was for, and safety concerns about unlit stops—together with problems due to the covid pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identifi ...
from 2020—caused the trials to fail.[
Lukas Foljanty, a shared-mobility enthusiast and market expert, keeps track of the different DRT schemes around the world and thinks a tipping point may have been reached in 2022. There were at least 450 schemes around the world, and in 2021 fifty-four new projects started within a three-month period.]
David Carnero of Europe-wide DRT technology company Padam said that successful DRT requires subsidies, must be delivered at scale, and must be part of an integrated, rather than competitive, transport policy.[

United Kingdom
Some DRT schemes were operating under the UK bus-operating regulations of 1986, allowed by having core start and finish points and a published schedule.[ Regulations concerning bus service registration and application of bus-operating grants for England and Wales were amended in 2004 to allow registration of fully flexible pre-booked DRT services.][Registration of Flexible Local Bus Services and Related BSOG Regulations]
UK Department for Transport Some services, such as LinkUp, only pick up passengers at 'meeting points', but can set down at the passenger's destination.
The Greenwich Association of the Disabled had earlier developed a prototype service, GAD-About, which offered pre-booked door-to-door transport for its members, inspired by similar minibus usage in church and youth clubs. That was then cloned as an easily scalable module, under the aegis of London Transport, to become the Dial-a-Ride service launched as part the general services of Transport for London (TfL), rather than as a bus service.
