For those outside Sydney, the New South Wales state government recently opened a new spaghetti intersection just west of Sydney's Central Business District.
It was supposed to solve traffic. Instead, it's turned into a giant car park:
"For the third straight day, motorists and bus passengers endured bumper-to-bumper traffic on the City West Link and Victoria Road. A trip from Haberfield to the Anzac Bridge on the City West Link averaged an agonising 44 minutes in the morning peak on Wednesday.
"Several months ago, Transport for NSW’s modelling had suggested traffic from the interchange would add only five to 10 minutes to trips on Victoria Road through Drummoyne and over the Iron Cove Bridge during morning peaks.
"Those travel delays have now blown out."
So what do motorists say when their shiny new road that was supposed to solve traffic instead turns into a massive traffic jam?
'Dude! Just one more lane!'
From the article:
"[Roads Minister John] Graham and his Transport boss Josh Murray appear reluctant to do what many motorists reckon is the obvious solution.
"That is, add lanes or make changes at the pinch-points that are causing the pain. A three-lane to one merge point from Victoria Road onto the Anzac Bridge, along with two lanes merging into one on the City West Link, are proving to be painful bottlenecks."

You're viewing a single thread.
@ajsadauskas induced demand is a stupid concept. If adding options increases traffic that means your.city is not serving residents. The point of a city is all the places people can get in them, if you have no place to go then move to Montana or someplace else with noplace to go. Note that I didn't say add more lanes, lanes are not very cost effective'
The reason adding one more lane is wrong is by the time slowdowns occure people are already packing cars in 6 times more dense than is safe and so you need not one more lane but 6 times as many lanes. That is expensive no matter how you look at it. (And probably requires layers of bridges and tunnels)
you need not one more lane but 6 times as many lanes
@fuck_cars @sydneytrains @urbanism @ajsadauskas That is about the right level of freeway for a city (entire MSA) of about a million people. I believe that the picture is for a city population of 7 million.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !fuck_cars@lemmy.ml, !sydneytrains@aussie.zone, !urbanism@slrpnk.net
The point is, if you spend the money on other modes of transport you can serve those residents without the negative externalities that come along with more traffic.
