Whoopsie! Sydney’s road planners just discovered induced demand is a thing, after opening a new motorway.

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.”

I think H.O.V. lanes are necessary, and the passenger limit should be such that traffic moves quickly in them They will require separate ramps from everyone else.

@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)

@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.

More lanes won’t help, but what the hell are those pinch points? 3 lanes down to 1? Did they never drive in a car?

Create post

This community exists as a sister community/copycat community to the r/fuckcars subreddit.

This community exists for the following reasons:

  • to raise awareness around the dangers, inefficiencies and injustice that can come from car dependence.
  • to allow a place to discuss and promote more healthy transport methods and ways of living.

You can find the Matrix chat room for this community here.

Rules

  1. Be nice to each other. Being aggressive or inflammatory towards other users will get you banned. Name calling or obvious trolling falls under that. Hate cars, hate the system, but not people. While some drivers definitely deserve some hate, most of them didn’t choose car-centric life out of free will.

  2. No bigotry or hate. Racism, transphobia, misogyny, ableism, homophobia, chauvinism, fat-shaming, body-shaming, stigmatization of people experiencing homeless or substance users, etc. are not tolerated. Don’t use slurs. You can laugh at someone’s fragile masculinity without associating it with their body. The correlation between car-culture and body weight is not an excuse for fat-shaming.

  3. Stay on-topic. Submissions should be on-topic to the externalities of car culture in urban development and communities globally. Posting about alternatives to cars and car culture is fine. Don’t post literal car fucking.

  4. No traffic violence. Do not post depictions of traffic violence. NSFW or NSFL posts are not allowed. Gawking at crashes is not allowed. Be respectful to people who are a victim of traffic violence or otherwise traumatized by it. News articles about crashes and statistics about traffic violence are allowed. Glorifying traffic violence will get you banned.

  5. No reposts. Before sharing, check if your post isn’t a repost. Reposts that add something new are fine. Reposts that are sharing content from somewhere else are fine too.

  6. No misinformation. Masks and vaccines save lives during a pandemic, climate change is real and anthropogenic - and denial of these and other established facts will get you banned. False or highly speculative titles will get your post deleted.

  7. No harassment. Posts that (may) cause harassment, dogpiling or brigading, intentionally or not, will be removed. Please do not post screenshots containing uncensored usernames. Actual harassment, dogpiling or brigading is a bannable offence.

Please report posts and comments that violate our rules.
