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.
Driving
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.
We build representative samples of drive times from other leading providers to benchmark our speed profiles against, ensuring that we always match up extremely closely.
We use these same samples to model congestion levels across the course of a 24 hour period on a typical midweek day.
Cycling
Our cycling model calculates cycling speeds based on elevation, ranging from 5 km/h to 60 km/h depending on the gradient.
Walking
Our walking model applies a standard walking speed 1.4 m/s
