The different configurations of Demand-Responsive Transport

Demand-Repsonsive Transport is flexible and can operate in different configurations: in line (fixed or virtual) or in zonal (free-floating, multi-zones or feeder)

Fixed line

Fixed line

The fixed route configuration is based on predefined stops served in a predictable order and at predictable times. The passenger is thus informed in advance and can anticipate his ride.

Virtual line

Virtual line

The virtual line configuration consists of a regular line where only the reserved stops are served. In this way, theitinerary can be followed in its entirety, or partially.



The electron-free configuration allows pick-up the passenger, regardless of his location, to drop off in a specific area without any time constraints. This configuration is to be preferred in the case of large territories where transport services are insufficient or too expensive.



The multi-zone configuration allows the service of several zones in a precise order. If the sequence of these zones is fixed, theitinerary within each zone is flexible and optimized.



The DRT zonal feeder service allows passengers to be picked up at a specific stop and dropped off in another zone, and vice versa. This type of line respects a schedule constraint, with fixed times that can be consulted in advance. It is a configuration to be favored for station/airport shuttles, or for school transportation.

The DRT  software: An essential tool for network management

The DRT software:
an essential tool for the good management of its Demand-Responsive Transport service

The objective of any good DRT software is to facilitate the use of the service while simplifying its management and providing real-time, reliable and complete information. It must be able to facilitate the users' experience in their booking and travel, the drivers' experience in their service, and the operators' one in their operation management.

As a true management and monitoring tool, the DRT software must make it easy to compile statistics to adapt the solutions to the needs and continuously improve service.

The DRT software: how does it work ?

The principle of the DRT software is very simple. It takes the form of a a suite of booking interfaces for users (application, website, interface for call center), a navigation interface for drivers and a management interface for operators.

  • When a passenger wishes to book a ride, he/she simply needs to go to his/her preferred booking interface (application, service website) or call the booking centre. He/she must then enter or communicate the desired ride, date, number of passengers, departure and arrival times.
  • The driver receives on his/her navigation interface (mobile or tablet application) a dynamic roadmap as it evolves in real time according to bookings and itinerary optimisations calculated automatically by several algorithms.
  • The management interface allows the configuration, analysis and monitoring of data relating to the service: geography, bookings, driver shift, lines, etc.
