Title: Surface Corrections
Post by: Peter_Arup on February 13, 2009, 04:16:00 PM

Roger/Alan

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??

Peter,

The manual correction is applied at all speeds.
