Is ther a UK page that has these official classifications? They maybe of

Rather than the density.. traffic speed could be more usefull? Example 
traffic_speed=20 @ 6:00-19:00 Mon-Fri , traffic_speed=15 @ 9:00-17:00 
Sat-Sun (yes, busier on the weekends!)/.
/If no traffic_speed then routers use the max_speed../
