How to set up a Dynamic Demand-Responsive Transport (DDRT) service

Dynamic Demand-Responsive Transport (DDRT) is a flexible public transport model that uses technology to match passenger demand with vehicle availability in real time. Unlike fixed-route services, DDRT allows passengers to book journeys when and where they need them, typically via an app, website, or phone.

DDRT typically operates within a defined zone or between key hubs, uses smaller vehicles (e.g. minibuses, taxis) to serve dispersed or low-density areas and features dynamic bookings, routed and scheduled based on demand

DDRT can be open to the general public or targeted to specific user groups and often integrates with wider public transport networks

When to use DDRT

DDRT is particularly effective when:

• traditional bus services are underused or financially unsustainable
• communities are spread out or have limited access to fixed-route services
• there is a need for first-mile/last-mile connections to transport hubs
• flexibility is required to meet varying travel patterns (e.g. shift work, rural access)
• you want to reduce social isolation by improving access to essential services

Resources

To plan and operate a DDRT service, the contracting organisation will need to:

• define the service area, operating hours, and eligibility criteria
• procure a technology platform for bookings, routing, and real-time tracking
• contract a suitable fleet operator (e.g. community transport, taxi firm)
• promote the service and provide user support
• monitor performance and adapt the service based on feedback and data

The technology provider typically offers passenger and driver apps, a central operations dashboard, real-time routing and scheduling algorithms, and data analytics and reporting tools.

Typical costs

Costs vary depending on the scale and technology used. Key cost areas include:

• the technology platform: you will pay licensing or subscription fees for booking and routing software
• vehicle operation: driver wages, fuel, insurance, vehicle tax and maintenance
• marketing and support: paying for outreach, training, and customer service
• monitoring and evaluation: data analysis and service optimisation

Funding may come from local authority budgets, rural mobility grants or innovation funds and/or partnerships with health, education, or social care providers.

Legal requirements

DDRT services must comply with:

• local licensing regulations for vehicles and drivers (e.g. taxi/private hire or PSV)
• data protection laws for handling passenger information
• accessibility standards, ensuring services are inclusive and equitable

If operating as a public service, the service may need to be registered with the Traffic Commissioner depending on its structure.

Next steps

You may find it helpful to consider these steps:

1. Assess local needs: identify gaps in existing transport provision and potential user groups
2. Engage stakeholders: involve local communities, transport operators, and service providers early
3. Select a technology partner: choose a platform that meets your operational and user needs
4. Design the service: define zones, hours, vehicle types, and booking methods
5. Pilot and evaluate: launch a trial, gather feedback, and refine the service before scaling up
