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
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
"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
“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.
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?
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. 🤷
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
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
@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
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.
Of course PBOT is going to immediately launch operation "think about it for a while" after driverists cut down their signs they stuck in the street for telling cars what to do, not like they always send crews out ASAP removing any guerrilla devices that potentially obstruct cars (oh wait...) Department of Letting Cars Boss Us Around here needs a better acronym. #Vision60or70something#PBOT#Portland#transportation#LowTrafficNeighborhoods#CarSupremacy#pdxBikes
@bluGill I think it's partly a blindness to the #InducedDemand, a mindset that these thousands of cars per day worth of thru traffic are going to be on some street anyway and that it costs the same whether they stay on the frequently-resurfaced arterial or the neglected side streets. The amount that could be saved in the long run by restricting car traffic to access-only is already invisible, besides being a long-term systemic drain on the budget, & many of the benefits are out of PBOT's scope.
The Regional Plan Association comes out against the NY State Department of Transportation's anticipated proposal to widen Route 17 in Orange County:
"To achieve the State’s climate goals, to promote choices across the state, and to ensure a healthy future, we must say no to any highway widening, including along Route 17. Investments in safety, transit, bicycle, and walking infrastructure where appropriate, and commitments to alternative land use patterns are essential."
"One editorial opined that the new parkways would, by relieving the traffic load on the Southern and Northern State Parkways, 'Solve the problem of access to Moses' Long Island parks for generations.' The new parkways solved the problem for about 3 weeks. '[...]3 weeks after they opened that I decided to go out to Jones Beach on a Sunday', Paul Windels recalls, '[...]by God it was as jammed the Southern State ever was!'. Moses announced that he had the solution: build 45 miles of new parkways."
"But traffic on the 4 other East River bridges was not falling off at anything near a comparable rate. The 8 million cars & trucks that Moses had forecast would use Triborough each year were supposed to be cars & trucks that had previously used the other bridges - particularly the Queensboro. Not only Moses, but all traffic experts [sic] who had studied the problem had agreed on that. Otherwise, where would these cars & trucks come from?" #InducedDemand
"Somehow, in ways [the traffic 'experts'] did not even pretend to understand, the construction of t[he Triborough] bridge, the most gigantic and modern traffic sorting and conveying machine in the world, had not only failed to cure the traffic problem it was supposed to solve, but had actually made it worse."
My new hill to die on as an urbanist transportation engineer is stop requiring traffic studies with development applications. They are an insidious cousin of parking minima, where some licensed engineer applies the ITE Trip Generation Manual, a collection of weak statistical analyses of very small samples, to figure out "how many cars to accommodate."
“There is a large and preventable burden of respiratory health due to current urban and transport planning. Our health and wellbeing should be the core of planning and policy-making.”
@BrentToderian It's been a slippery slope from "allowing for the movement of people and goods", to the non-movement* of overpriced status symbols and social armor that we see in cities today (*interspersed with lurching violent displays of power). People need to understand that #InducedDemand means you get the traffic that you build for, and what you see is exactly what our current models, standards, and "best practices" of #trafficEngineering will deliver: more cars, deaths, and congestion.
At Port Phillip Council tonight, councillors claimed that "you can't ride a bike if you're grocery shopping, if you''re dropping your kid at dance class, if you've got a couple of kids to take somewhere, if you're old, if you're disabled, if you don't want to get wet". It's like they haven't seen a bike outside of the Tour de France! #cycling#melbourne#CoPP#BikeLanes
