Demand-Responsive Transit

Detailed overview of innovation with sample startups and prominent university research

What it is

Demand-responsive transit (DRT), also known as microtransit or on-demand transit, is a flexible transportation service that operates based on real-time passenger requests. Unlike fixed-route bus services, DRT vehicles adjust their routes and schedules dynamically to pick up and drop off passengers at locations convenient to them. This innovative approach to public transportation provides a more personalized and efficient alternative, particularly in areas with low-density populations or for connecting riders to existing transit hubs.

Impact on climate action

Demand-Responsive Transit revolutionizes low-carbon mass transit by optimizing routes based on real-time demand, reducing empty trips and congestion. By efficiently utilizing resources, it minimizes emissions and encourages public transportation use. This innovation fosters a shift towards sustainable urban mobility, contributing significantly to climate action and reducing environmental impact.


  • Mobile Applications: DRT relies heavily on mobile applications, allowing passengers to request rides, track vehicle locations, and make payments.
  • Real-Time Data and GPS Tracking: GPS tracking of vehicles and real-time data on passenger requests are crucial for enabling dynamic routing and scheduling.
  • Optimization Algorithms: Sophisticated algorithms are used to efficiently match passengers with vehicles, optimize routes, and minimize waiting times and detours.
  • Cloud Computing and Data Analytics: Cloud platforms process and analyze data from vehicles and passenger requests, enabling real-time decision-making and system optimization.
