As cities grow and travel patterns become more dynamic, traditional fixed-route transit systems often fall short of meeting modern mobility needs. That’s where Demand Responsive Transport (DRT) comes in—offering flexible, adaptive solutions to address variability in public transport demand.


DRT nedir?


What Is DRT?

DRT refers to transit systems that adjust routes and schedules based on actual passenger demand rather than fixed timetables. It is especially useful in:

  • Low-density or rural areas

  • Off-peak hours

  • Regions with unpredictable demand


By responding to real-time or observed demand, DRT enables operators to deliver more efficient and tailored services while minimizing resource waste.


Types of DRT Systems

DRT systems are generally categorized based on their level of flexibility:


1. Fully Flexible Systems

Vehicles are dispatched entirely based on passenger requests. These services typically operate through mobile apps or call centers, allowing real-time bookings—similar to on-demand minibuses or shuttles.


2. Semi-Flexible Systems

These operate on a predefined route but can deviate slightly or skip/add stops depending on demand. Common in rural areas, this model balances reliability and adaptability.


3. Low-Flexibility Systems

Routes are mostly fixed, but stopping at certain locations is demand-dependent. Often used during evenings or low-demand periods to reduce unnecessary stops.


Why It Matters

DRT systems offer cities a smarter way to serve passengers where and when they are needed, without compromising operational efficiency. They:

  • Increase service coverage

  • Improve cost-effectiveness

  • Enhance user satisfaction
