"Adding highway lanes to deal with traffic congestion is like loosening your belt to cure obesity." - Lewis Mumford in 1955.
We’ve known this for a LONG time, but we’ve put massive energy, money, space, and time into pretending we don’t know it. #InducedDemand#lawofcongestion

Public space is the most valuable resource of #cities, and they squander it on cars. Not "but I need to drive" or "economic activity and essential mobility blah blah blah", we could have all of that with a fraction of the asphalt. Not even "driver convenience". No, it's just stupid extra lanes for the worst drivers to pass law-abiding ones and go wait at a red light sooner, and empty free parking. Wasted. #InducedDemand#CarsRuinCities#Urbanism
@daihard@LukeBornheimer but the status-quo of a 4-lane arterial through the countryside is itself absurd (as is the tendency to excuse cars being the only option for that long-tail of use cases even when they're only 4 miles). Even in the context of SF where the population is much denser and some places might require car access, the lane allocations of existing space are the main thing keeping people driving. There needs to be space & status for bikes. #InducedDemand
... it's profoundly sad, how engineers can take a class on hydrology and recognize [how the system / network design creates a flood] ...walk down the hall to a traffic class, and look at the same system dynamics and not reach the same conclusion." #StrongTowns#InducedDemand
A man on a bike was killed with a drunk driver here seven years ago next week, and nothing has changed except the paint wearing off. Does #PBOT have no respect for people on #pdxBikes, or do they not know how to do better? #Drivers from Beaverton aren't a force of nature, they're simply a result of choices made by "professional Engineers" (like that lane width 🙄 .) #InducedDemand created by the policy of maintaining extra freeway lanes on our surface streets.
People who honk at other #drivers need to realize that they are not doling out justice, just being rude to everyone around them, like loudly farting in an elevator but intentionally. Maybe if they got a ticket in the mail for $165 (ORS 815.225)
And the driver who ran the red from the right, is making a u-turn here to turn right because she's skipping the left-turn queue onto Barbur from Terwilliger northbound / freeway offramp. 🙃 #InducedDemand
people keep literally saying exactly how to transform your city urgently and without a lot of money but mayors and traffic Engineers just roll up the windows and stare straight ahead at a red light. #ClimateAction#Transportation#InducedDemand#TacticalUrbanism#JFDI
@Ramonsta72
Durchfahrverkehr in Städten durch Hochstraßen zu begünstigen führt nur zu mehr Kfz-Verkehr - an Stellen, wo Menschen sich hauptsächlich aufhalten (#induceddemand). Insofern sind Hochstraßen nur vordergründig (aus den von Dir genannten Gründen) eine gute Idee. Nach Hinten raus sind sie es nicht.
The barrier to #30daysOfBiking for most people was never the weather, hills, or distance, it has always been the luxury car and/or SUV #drivers with tinted windows who don't stop for crosswalks, or otherwise brandish their vehicle as a weapon to cow people into giving up their rights to public space.
Of course, the #drivers who FTY at #crosswalks and block #BikeLanes also came up the other side of the hill, using the small neighborhood street (which lacks sidewalks on one side, barely complete on the other) as their cut-thru to avoid driving on nice big streets that go around the hill to within a block of the school with nice 💸💸 traffic signals. This is what you get for leaving every street open to cars for cutting through in every direction: every street has too many cars. #InducedDemand
“For years, advocates have been sounding the alarm on the worsening epidemic of traffic violence in our community and proposing solutions which have been ignored by the City Council,” Sarah Iannarone, executive director of nonprofit The Street Trust, said in a press release. “Of course the problem continues to worsen.”
@greendesignek “Where we have invested, we have had success,” Mapps said -- ignoring that the entire network is an ongoing investment in cars-first-always-only and continued failure to urgently reduce and reallocate car space is an ongoing investment in killing 60-70 ppl/yr with Portland traffic. #InducedDemand will just keep doing its thing for as long as we let it.
We have a big problem in #DavisCA with folks who pretend they're riding a e-assist cycle when they like those laws, only acting like a motor vehicle when they like those laws.
This guy illegally passed me on the right when the light turned green (right turn only lane), then pulled ahead and onto the cycle path. It's a Vespa-like motor scooter.
We have a place in town that calls itself AMP Bikes that sells these and food delivery now races along cycle paths and MUP. #BikeTooter#Cycling
@meganL I think the phenomenon of #InducedDemand also applies when the vehicle operator does what seems obvious / what they believe they can get away with. Infrastructure shapes behavior, but the people who build infrastructure are bad at understanding or predicting behavior. The Dutch have this problem with gas scooters too (and maybe high-power ebikes?) but it seems like that was a policy choice of banning them from the roadway. 🤷
interview with "Megan Kimble, an Austin-based journalist and the author of the new book City Limits: Infrastructure, Inequality, and the Future of America's Highways. In the book, she follows the story of three major freeway fights playing out in the state of Texas over the period of about four years while channeling the movement of freeway removals and #reparations nationwide." #InducedDemand#NoMoreFreeways#CarsRuinCities
The city #transportation system at each end of the #trains is as much a part of the #InducedDemand as the service itself. If you get there and require a car for #mobility, maybe needing to take slow, infrequent #transit to an airport on the edge of town to get a rental, the train has lost its edge vs #shortHaulFlights in time, if not expense. Taking a folding bike on the train is an okay workaround for some, ridehail/taxi activity at train stations suggests a need for bikeshare + #cargoBikes
I'm feeling grumpy so I'm finally gonna say some stuff about the book Killed by a Traffic Engineer and why it's a stupid title for a book if you want it to create change in how streets are designed. https://islandpress.org/books/killed-traffic-engineer

@HayiWena would a "reasonable Engineer" "improve traffic conditions" by maintaining designs that yield a network which is clearly hostile to alternative means of transportation, given the decades-long-studied irrefutable fact of #InducedDemand? "in accordance with ... municipal regulations, standards and manuals" - but the MUTCD, at least, says explicitly that the guidance is no substitute for an Engineer's judgement. Certainly there is windshield bias of judge/lawmakers, but buck stops where?
