I thought this was already common around the world, say in Europe. Where 4 lane / artery / highways get brighter, whiter (bluer) lights, while 2 lane feeders and smaller roads have warmer yellow lighting. It produces an interesting nighttime aerial effect as the color indicates the nature of the street. I can't find any source to corroborate so I'd love if someone with more worldly travel experience could corroborate. I first became aware of the phenomenon playing Cities: Skylines, a European developed city builder game which features the multi-colored street lights in European skins.

IDK, but this could simply be an effect of bigger roads getting more frequent upgrades, and/or bigger roads tolerating a larger cost per light since the total cost per meter of road is already higher.

  Have more faith in European engineering and regulation, it's something we excel at :-) There are 9 grades of lighting, ranging from that required on a motorway interchange, through urban motorways, rural motorways, major roads, etc, to residential areas. Here's the relevant standard: http://vili.pmmf.hu/~mate/oktatas/VilTech_levelez%F5/EN13201%20Guide.pdf http://vili.pmmf.hu/~mate/oktatas/VilTech_levelez%F5/EN13201... (BS = British Standard, but EN = European Norm, so the British Standard implements the European Standard. [I think that's how it works.]) This is the code of practise for Britain: http://persona.uk.com/orga46newark/ha_docs/disposit_docs/dd101-dd200/dd164.pdf http://persona.uk.com/orga46newark/ha_docs/disposit_docs/dd1... The "Manual for Streets" has an overview, from p120: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/341513/pdfmanforstreets.pdf https://www.gov.uk/government/uploads/system/uploads/attachm... (Similar documents should exist for every EU country, but the British ones are in English and easiest to find with Google.)
