>>But these tags would mostly need time specifications too:
>>  expected_speed_00:00-09:00 = 120 Km/h
>>  expected_speed_09:00-11:00 =  30 Km/h
>>  expected_speed_11:00-16:00 = 120 Km/h
>>  expected_speed_16:00-22:00 =  30 Km/h
>>  expected_speed_22:00-24:00 =  30 Km/h
>>  expected_speed_holiday = 0 Km/h

How would this work, as If i walk along the side of a dual carrageway the 
data would say average speed 3.5mph.  In contrast a car may say 70mph, 
therefore the average speed of the road is about 37mph so incorrect, as on 
foot I could have gone faster, but was limited by my own phisical abilities 
rather than the road and its features.
