I have a project that involves porting a lot of information from ordnance survey to a spatial database. From that database I'm going to extract the information I need for a routing application. However, I have a problem as I'm not sure how no turn works.
I have trawled through the ordnance survey documentation but haven't been able to work out how no turn in the environment qualifiers apply. My question is, from the data in ordnance survey, how do you find out which links you can't turn onto (from link x)?
Any help would be appreciated.
