I know who the lighting designers are for Melbourne City Council. Whilst street furniture in general wouldn't be a problem for astronomy and the catenary lighting in the alleys of Chinatown are examples of good lighting, maybe you don't want a lot of this in residential suburbs. There's a large intersection in Melbourne lit by blue light from a catenary, this might be decorative but not astronomy friendly.
To demonstrate that not all street lights are created equal, there is tria/testing area outside of the Eureka Skytower, it is easy to pick out because the lights under test are so different from each other, it's worth a look.
Obviously Melbourne City Council get a huge say in how the lighting is done and it's mostly appropriate for a city, this isn't the case in the suburbs.
