How do they decide if a road is a street or an ave, drive, blvd etc?

Answer 1

By 'they' I assume you mean the secret cadre responsible for behind-the-scenes urban development decision-making. Planning councils will always try to make it seem that public consultation plays a role in such decisions, but in fact these matters are manipulated by an elite clandestine group of grey eminences suffering from nothing better to do with their time, and who were sick of having out of date maps in their glove compartments (or GPS systems) anyway.

This group meets on a monthly basis in luxurous settings around the world and informally examines all current urban planning developments under way. Being familiar with global local histories and current with dozens of newspapers, they usually take an hour or two to determine appropriate names for all as-yet-nameless streets, plazas, courtyards, parks, and so on. As you might imagine, 'in jokes' often factor in, however - sadly - these would be incomprehensible to any not of their ilk.

'Avenues' and 'Streets' are assigned based on consistency with the local infrastruture, 'Boulevards' are invariably used by the cognoscenti for strolling (and are chosen accordingly), 'Courts', 'Places', 'Drives' etc. are thrown in to break up the monotony and, as previously suggested, to confuse those not in the know and divert unwary delivery drivers.

Then the 'fun' begins as members of the group wager on each others success or failure in the complex political manoeuvering necessary to influence these decisions in real time. Fortunes are won and lost (ho hum).

Of course, this polyglot group (known simply as the 'nomopoly') has many other interests. But to list even a fraction of them would be incredibly boring.

At one time a rival group calling themselves 'Technocrats' advocated for a rational transportation & energy system that might have resulted in astonishing efficiencies (by current standards), but their political skills were hopelessly lacking and - for practical purposes - they soon vanished (although technically their organization still exists).

Answer 2

Streets and avenues intersect, not parallel. Boulavards have a traffic divider in the center. Drives are usually in residental areas.

Answer 3

The person who names it decides if it sounds cool to say Street or Avenue. No, I think it has something to do with N, S, E, and W directions.

Answer 4

no clue

to confuse us maybe

my street has a: street , court, terrace, place, etc.

it makes life difficult for delivery people

my housemate used to just buy whatever food was delivered
so he would get a surprise dinner

after the 100th time redirecting the delivery people I don't blame him

Answer 5

i think a boulevard is classified by having plants down the middle (or maybe thats an Ave?)

Answer 6

in my town streets run north south ave run east west

Answer 7

depends what word flows best with the other name.

Answer 8

It's random, there is not rhyme or reason, seriously.
