We're looking for a Transportation Researcher with a passion for sustainable and equitable transportation strategies and a background in planning, engineering, or a related field. Applications due May 5. https://ssti.us/join-our-team/
"75% [of drivers yield to people in a crosswalk] at 20mph — a speed at which traffic rarely moves on auto-centric U.S. streets... 30mph, just one in eight of them yielded" #VisionZero#CarsRuinCities#trafficEngineering
So, in 1959 some bright sparks decided that San Francisco needed a freeway loop around its downtown, and built this thing right through the Mission. Its rightmost lane is, horizontally, perhaps six lateral feet from the sidewalk and twenty or so feet up.
Turns out this is what happens when it's rained. Every ten seconds or so a large puddle re-forms up there, and the next big vehicle throws a curtain of water all over the sidewalk and the walkway at Rainbow Grocery.
This evening there was a man just hanging out on a bench just outside the splash zone warning people about it, but also laughing at the stupidity of it all.
@Iragersh the profession of #trafficEngineering has ceded their authority to traffic counts and highway design manuals, but I think street design could do a better job than industry regulation, and quite a lot sooner if they would delegate the placement of jersey barriers to children.
#PBOT's "traffic calming" projects are such kid-gloves weaksauce that doesn't pretend to control the kinds of drivers who are actually making our streets feel unsafe. Their machines are 5-7000lb lumps of steel being flung around at 30mph with 400hp and Portland has, after a decade of organizing by neighbors and careful work by professional #trafficEngineers, delivered like a dozen rubber bumps and some paint. #tacticalUrbanism is this stuff but overnight, & then iterate
It is so exciting to see traffic signal programming like this in Madison. This is from one of our city traffic engineers (who also happens to be a regular cyclist).
“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.
@jimvernon This is more of a #trafficEngineering question, as to whether it should be standard practice to put stuff in the way of impermissible maneuvers, where kids are crossing a high-speed street.
"The reaction from walkers, bikers, families, and nearby business owners was overwhelmingly positive."
“We'll have to see how we can apply pressure and what it takes to get the city leaders to listen or do something for safety.” (Try not letting #trafficEngineers over-inflate the costs with their convoluted excuses for trying to preserve car speeds.)
People have presented congestion pricing as though its only benefits were funding the MTA or reducing congestion, but Sadik-Khan has at least one more:
"To reap a huge street dividend. Congestion pricing is projected to reduce traffic by 20 percent. That means one in five cars will disappear. So there’s an opening for the city to innovate and create separate lanes for e-bikes, scooters, and mopeds that don’t belong in regular bike lanes or mixed in with traffic."
"This is the standard method that the Netherlands uses to prevent people from driving through a neighborhood, and they make the streets safer and more enjoyable for everyone who lives there."
Q8. Summer gatherings like concerts or ballgames can bring together large collections of bikes. Seeing these makes me feel happy. If/when you have been around a large group of bikes, where were you, and what was happening that brought all those beautiful cyclists together? #BikeNite
The Bureau and Budget Advisory Committee is having a hard time figuring out how to spend too much money on cars and then also somehow spend money we don't have on adding safety, staff treats the committee like a panel of fundraising advocates, total farce #VisionZero#Portland#pdxTraffic
My 12yo is waging a protest against gravity being hard, I mean I totally understand how PBOT and our entire city govt is institutionally wishing cars would pay full price but be cheap and the streets would be empty like a car commercial but bustling with economic activity, and all of it electric & powered by cinnamon-scented #UnicornFarts. #climateWishing#CarsRuinCities#InducedDemand#ScienceDenial#TrafficEngineering
Florida's #CompleteStreets guidance tells road designers how to translate context into target speeds, including transitions through rural town centers.
It also tells local governments what their built environment should look like.
