Demand responsive bus service

In 2019-20 we ran two service trials in the London Boroughs of Sutton and Ealing to explore how demand responsive buses could:  

  • Complement current public transport services 
  • Reduce car dependency

How it works

Demand responsive bus services take multiple passengers heading in the same direction and book them into a shared vehicle. 

The services operate from 'corner to corner', so there are no fixed routes or bus stops. The app shows people a clear map of where their virtual bus stop is instead. 

The trials 

We ran the GoSutton trial service in collaboration with ViaVan and Go-Ahead.

It operated from 28 May 2019, Monday to Sunday 06.30 to 21.30. Journeys cost between £2 and £3.50 (depending on time of day and journey length).


We ran the Slide Ealing trial service in collaboration with RATP and MOIA.

It operated from 13 November 2019, Monday to Sunday 06:00 to 01:00. Journeys cost £3.50 (with promotions available).

Buses picked up and dropped off passengers within 150 metres of requested destinations. Passengers could book journeys by phone or through the GoSutton or Slide Ealing apps. 

We suspended and closed the trials in Spring 2020 following Government advice to stop non-essential travel.

Research findings 

The trial learnings and technology are already informing a range of projects within TfL and nationally. 

We also committed to publishing the research following the trial conclusion. Read the findings in our report below.
