* Restricted marking for motorway/trunk/primary
* Add access marking for highway=pedestrian
* Update functions.sql
highway=pedestrian should support restricted access
* Change pedestrian access marking colour
Change pedestrian access marking colour to common light shade of grey.
Also consolidate names.
* Interpret additional access tags
mode specific access tags relevant to primary mode of highway interpreted to determine access marking for:
Road types (motorcar > motor_vehicle > vehicle)
Footway (foot)
Cycleway (bicycle)
Bridleway (horse)
* Function load in CI
* Add carto_path_primary_path
* Moving customers, permit
Following discussion moving:
access=customers -> "restricted" marking
access=permit -> "no" marking
* Major changes in response to comments
Functions renamed for clarity
Changed logic for mode-specific tags, only ignoring 'unknown' values
unknown access type return for unknown/uninterpretable
path promoted to cycleway/bridleway in SQL rather than MSS
* Use foot primary mode for highway=pedestrian
* Typo fix
* Remove incorrect END statements
* Fix regression on introducing explicit unknown
* Fix regression for highway=path
* Alter 'destination' outcome for 2-state access
'destination' on path / footway etc. interpreted as 'yes' (matching current behaviour)
* Simplify functions.sql
Reduce number of functions
Tidy comments
* Tidy access functions
Consistent formatting of CASE/WHEN
Use more idiomatic COALESCE(NULLIF(...),)
* Update functions.sql
Change argument name accesstag -> accessvalue
Improve documentation
Simplify logic for promoted paths
* Remove obsolete comment from MML
* Avoid unknown overload
Return "unrecognised" rather than "unknown" if access restriction is not one of recognised values
* Extend code comments
Note on short-circuiting logic in carto_highway_int_access
* Fix broken bridge on path
Bridge not being rendered on highway=path
