Speed limits on major roads in the UK
Ito Map is a global slippy overlay map service from Ito World which offers a range of map views to highlight many 'hidden' data layers within OpenStreetMap. See Ito Map ideas page for details and discussions about additional map layers.

Ito Map was released for the UK and parts of northern Europe on 18 March 2011 and was extended to cover the USA, Canada and the Caribbean on the 23 March 2011. It went global on 31 March 2011 with a further four rail related layers added on 7 April 2011. A 'building heights' layer was released on 12 April 2011. Since then new layers have been added. In August 2012 British Isles nodes were added with some new layers with support for them. In September 2012 to coincide with SOTM the ability to click on maps and get additional information was added. Ito Map was developed by Ito World with support from Ideas in Transit, a five UK government funded research project.
The map data is normally updated after 7 days.

Below are just some of the map layers available within Ito Map. Check the product itself for the complete current list. You can request new maps or suggest changes to existing maps using the Ito Map ideas wiki page.
The barriers overlay highlights a number of different types of barrier=*. Hedges are shown as red, fences as green, walls as blue and central_reservation is light blue. Other types of barrier are currently shown as black.
Buildings and addresses
Shows building=*s as red if there is no associated addressing using addr=* or name=*. Buildings coloured green have a house number using addr:housenumber=*, blue ones have a house name either using name=* or addr:housename=*. Address ranges using addr:interpolation=* are shown as green/blue lines.
A view showing ways which are tagged with fixme=*.
Green space access
The 'Green space access' layer shows public accessibility to green spaces (see linked article for details).
The Layer overlay shows ways tagged with layer=*. Layers 2,3,4 and 5 are in shown in orange, layer 1 in red, level 0 in green, level -1 in blue and levels -2, -3 and -4 are in light blue.
An Ito Map overlay showing navigable waterways which are tagged with waterway=* and a value of canal, drain, stream or river. If they also have boat=yes they are shown in red and if boat=no are shown in blue; rivers without either are shown in black. The coastline is green, lakes are brown and reservoirs in purple. waterway=riverbank is not displayed to avoid obscuring the colour coding of the river itself.
Railway loading gauge
Highlighting the number of tracks in railway=tracks. Note that it is generally considered preferable to create a way for each track in which case a twin track line will be shown as two parallel way with tracks=1 rather than one way with tracks=2.
Ito Map overlay showing railway elements. railway=rail is shown in black. ways with railway=rail and also railway=siding (or yard or spur) are shown in light blue. railway=subway is shown in red, railway=light_rail in blue.
The deprecated railway=siding is shown in red. railway=platform are also currently shown in red. railway=narrow_gauge is shown in green.
Speed limits km/h
Ito Map overlay showing the value in maxspeed=* for all ways with highway=* suitable for km/h areas. yellow for maxspeed of 'none'. dark blue for 130/120/110. light blue for 100, purple for 90/80, red for 70/60 orange for 50 and green for 5/10/15/20/30/40. Where a maxspeed is set to another value is it shown as 'tan'. If maxspeed is not set then for road classes of tertiary and higher then roads are shown in black.
Speed limits km/h: major roads
Ito Map overlay showing the value in maxspeed=* for highway=motorway, highway=trunk and highway=primary for areas where speed is shown in km/h. Yellow is used for ways with maxspeed set to 'none', dark blue for 130/120/110, light blue for 100, purple for 90/80, red for 70/60 and orange for 50. Where a maxspeed is set to another value is it shown as 'tan'. If maxspeed is not set then for the above road classes the road is shown in black.
Speed limits mph
Ito Map overlay showing the value in maxspeed=* for all ways with highway=* suitable for areas that use miles per hour. Yellow for maxspeed of 'none' (some states in the USA), dark blue for '70 mph' (and '70mph'), light blue for 60/65 mph, purple for 50/55 mph, red for 40/45 mph, orange for 30/35 mph and green for 5/10/15/20/25 mph. Where a maxspeed is set to another value, it is shown as 'tan'. If maxspeed is not set then, for road classes of tertiary and higher, roads are shown in black. Note that speeds must end in 'mph' with an optional but preferred space between the number and the letters 'mph'.
