We are currently looking at surface corrections and how to approach them in our models. Could you please confirm or clarify the following:
When surface types mentioned in CRTN are used e.g. Bitumen, the surface correction is only applied for road links with a speed of >75 km/h
When a user-defined 'Correction' is applied (and you put your correction in dB in the texture depth field), is this applied to ALL road links, or just those with a speed of >75 km/h??
