How do you calculate journey times?

An overview of how our public transport, driving, cycling, and walking models work.

Updated over a week ago

Our method of calculating travel times depends on the mode of transport.

Public Transport

Our public transport journey times are calculated using actual public transport timetables. We gather up all available timetable data, and consolidate it into a holistic model for all modes of public transport combined.


Our driving model is built from the ground up, and combines a range of data sets to construct speed profiles based around properties of the network such as road types, the surrounding area, and features of the road itself. These speed profiles are then benchmarked on test maps, fine-tuned, and then set live.


Our cycling model calculates cycling speeds based on elevation, ranging from 5 km/h to 60 km/h depending on the gradient.


Our walking model applies a standard walking speed 1.4 m/s
