Visually differentiate roads speed limits

[ignaciolep]

Need: Be able to see on map each segment speed to know where is missing or incorrect.

Proposal: Add a new map data layer that would render a color line or halo next to each roads segment that have the maxspeed tag, using different colors to visualize each speed range.

For example:

kmh:
10: dark red (10-19 kmh)
20:
30:
40:
45:
50:
60:
70:
80:
90:
100:
110:
130+: dark green

mph:
5: dark red
10:
15:
20:
25:
30:
35:
40:
45:
50:
55:
60:
65:
70:
75:
80:
85+: dark green

Maybe this is a job better suited for an OSM-Validator, showing segments which have big differences in speed Limit with adjacent segments.

ITO World has a map showing missing speed limits from major/minor roads: http://product.itoworld.com/map/125
They also have maps showing the speed limits in km/h, mph and both: http://product.itoworld.com/map/group/19

That's the idea. Something like that but integrated in iD, would enable editors to contribute speed limits by easily visualizing where the speed limit is missing or wrong.

The just-merged KeepRight integration #5201 includes a check for missing maxspeed tag. That's a good start for now, but I agree it would be nice to give users more of an ability to add custom styling to highlight issues with the map that they are interested in.
