Advice: Do not abbreviate or contract name tags; for example, use Saint Margaret instead of St Margaret. Why? Think search engine design; maximal up-front quality information, automated presentational reduction for dense cartography (e.g. OS A–Z). The short_name key is ideal for this.

Footpaths: Use surface=bitmac, rarely surface=tarmac[adam], nearly never surface=asphalt. See difference between tarmac, asphalt and bitmac.

Notable Information:

• According to Department for Transport and Speed Awareness Instructors, non-motorway dual on/off-slips are 60 mph if not otherwise signed.
• Private, unadopted roads may tolerate certain types of trespass, but they remain private regardless of physical barrier or signage. Speed limits do not apply when interpreting ‘to which the public has access to’ in the legal sense (rather than physical) from UK Road Traffic Act 1988 s. 192.

Areas worked on: Road names, Speed limits (prefer GB:national over GB:nsl_single), Tertiary/Unclassified road references (highway_authority_ref), Power networks, Public transport routes, Post boxes, Winter salting routes, Schools, Churches, Give-way signs (for routing cost estimates at same classification cross-roads), Village signs, Building addresses.

Inspiration: The 16 months it took TeleAtlas to update their map after I reported car/truck-blocking bollards near my home with a photo. In that time frame, I had contributed to Norwich mapping to near total road network completion. The continued uselessness of TomTom at updating their own map from volunteered speed limit feedback. The abhorrent tax upon tax upon tax of OS maps.
