The OS MasterMap Highways Network with Average Speed product identifies the average speed travelled across all roads in Great Britain at different times of day. The average speed is calculated based on detailed historical speed information, which is collected annually by in-vehicle telematics devices and mapped to each unique OS MasterMap RoadLink TOID. The average speed value is provided in both directions. The average speed is provided in km/h and for each road link.
The average speed product provides a detailed breakdown of the speed travelled at different times of day. The times of day available are as follows:
07:00 – 09:00 Monday – Friday (Peak AM)
10:00 – 16:00 Monday – Friday (Off Peak)
16:00 – 19:00 Monday – Friday (Peak PM)
19:00 – 23:00 every day (Evening)
00:00 – 04:00 every day (Night-time)
Weekend
