In the race to modernize public transport, many cities have fallen into a common trap. They see "Demand-Responsive Transport" (DRT) and think of it as a government-subsidized Uber. They focus on the app, the immediate booking, and the door-to-door convenience.
But there’s a problem: If you run your buses like taxis, you get taxi economics. You end up with expensive vans scrambling to respond to last-minute requests, driving half-empty across the city. This isn't a modernization of the bus; it’s just a very expensive way to compete with ride-hailing apps.
In this article we explore:
We need to move away from the "expensive van" narrative and toward a model of Cost-Effective bookable predictability.
The "Scramble" vs. The "System"
The core difference between a tech-enabled taxi (the model used by some DRT, on-demand bus providers) and a modern DRT bus service comes down to data and visibility.
Imagine four people in the same neighborhood all need to head toward the city center at roughly 8:30 AM.
- The Taxi Model (Last-minute only): Passenger A books at 8:15. A vehicle is dispatched immediately. Passenger B books at 8:17. Passenger A is already moving, so a second vehicle is dispatched. By 8:25, you have four different vehicles on the road for four people. This is the "on-demand scramble". It’s inefficient, expensive, and increases congestion.
- The Bus Model (Advanced Booking): Because the system encourages advanced booking, the algorithm "sees" all four passengers the night before (or even an hour before). It realizes they are all in the same area. It assigns one 6-seater minibus to pick up all four. Optimising bus use, saving the cost of multiple buses on the road a boosting sustainability value.
Independent studies show that many reactive, unstructured microtransit services average around 2.5–2.7 rides per vehicle-hour. Pre-optimized services, such as Liftango's DRT solution, can perform significantly better. For example, one of our UK DRT services achieved an average of 3.5 passengers per vehicle-hour in 2025, clearly outperforming typical reactive models.
Independent reporting also suggests that in larger city deployments, where demand is high and full pre-optimization is possible, structured systems can reach up to 9 rides per vehicle-hour.
The result? Equal or better passenger service, offering flexibility alongside the certainty missing from last-minute service models, with an increased reduction in operating costs and carbon. That’s a DRT bus service, not a taxi service.
Why Advanced Booking is the "Secret Sauce"
Many platforms treat advanced bookings as an afterthought, only assigning a driver 30 minutes (or less) before the trip. We believe that guaranteed bookings are the backbone of public transit.
Commuters, people with medical appointments, and students don't want "flexibility" as much as they want certainty. By guaranteeing these trips in advance, we give the matching algorithm the data it needs to optimize the route.
The Rule of Thumb: More data in advance = better route planning = higher efficiency.
When trips are booked this way, each reservation is locked into its assigned time slot, not left to chance shortly before departure. Passengers know their ride is confirmed, their pickup window is protected, and their arrival time is planned for. That certainty builds trust in the service while giving the system richer data earlier, enabling smarter routing, higher vehicle utilization, and fewer empty miles.
The result: reliability for riders, reduced congestion and stronger transport networks - especially in areas where traditional public transit falls short and shared mobility can fill the gap.
Bridging the Gap, Not Replacing the Route
True DRT shouldn't compete with fixed-route buses; it should feed them. In places like Sharjah or West Yorkshire, our DRT services are working best when it acts as the "connective tissue" of the city - linking neighbourhoods with core transport corridors rather than duplicating them. The same logic applies across all modes: true DRT feeds rail, connects into bus spines, links with ferry terminals, and complements existing transport systems wherever demand is too thin or dispersed for a full fixed route. When properly integrated with aligned transfer points, coordinated fares, and clear passenger information it strengthens the entire network instead of competing with it.
DRT offers the personalized routing of a car at the price of a bus. For example, services we run across the UAE, have fares of around $2 - $3, keeping it affordable, and making the service accessible to everyone, not just those who can already afford a private car.
This pricing model is only sustainable if the buses are operating with high "pooling" rates, something you can’t achieve if you’re just chasing last-minute pings like a ride-hail app and misses the point of supporting all communities.
The Bottom Line: Run Buses Like Buses
The goal of DRT isn't to turn the city into a fleet of private shuttles. It’s to make the bus work for the modern world.
We need to move away from the "expensive van" narrative and toward a model of Cost-Effective bookable predictability. When we prioritize integration, advanced booking, and passenger pooling, we aren't just giving people a ride, we’re building a sustainable transit network.
Flexible buses that work like buses - not expensive taxis pretending to be DRT.
