In the NSG the start/end of Traffic Sensitive info, reinstatement categories, private/public extents, etc. is recorded with grid coordinates.
In OneNetwork when a street is (correctly) identified as being both part private and part public the entire USRN line is coloured pink (designation on part of street).
If the layer instead showed the correct extents of special designations in each section it would be more useful for activities such as reviewing Traffic Sensitive streets.
