Driving in Portugal a couple of weeks ago was the first time I had really experienced frequent roundabouts...
...and wow are they addicting!! So many times where you can just fly on through what would have been a slow stop-and-go at a stop sign or a several minute wait at a light.
I really hope Japan picks them up!

“You don’t need an expensive overpass; you don’t need a well-designed underpass. You just need to use a different type of curb.”

And then the koalas just vanished...
Speeding cars, road designs, roaming dogs and disease are the biggest koala killers.
Logging and sprawl should also be added to the list of extinction makers"A database tracking hospital admissions and deaths reveals the devastating impact cars, disease and dogs are having on the South East Queensland koala population"
.
"In the five years between 2009 and 2014, 52% of reported wild koala deaths were caused by car strike, 34% were from a chlamydia-related disease and 14% were because of a dog attack."This equates to 1,431 koala deaths from a car strike, 943 chlamydia-related deaths, and 395 dog attack deaths in just five years."
"Remember that these deaths were just the reported cases, so the real numbers would be significantly higher."

Never understood why Canadians & Americans seem to not like the roundabout. It keeps traffic flowing & statistically it causes less collisions.
I see a lot of local opposition whenever they're discussed.

I'm reviewing older studies and thought I'd share this one from Charlotte, NC.
Incorporating #CompleteStreets elements into road project adds a little to the costs, but overall fluctuations in construction costs dwarf those. https://doi.org/10.3141/2393-15

@capntransit @jerryschippa I was just going to bring that discussion over here.
There's been some research looking at traffic impact studies and trying to make them better. But researchers also warn they might not hold up in court much longer, given their shaky foundation. https://ssti.us/2023/04/03/researchers-warn-traffic-studies-could-face-more-legal-scrutiny/

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.

Chicago offers lessons in automated traffic enforcement:
1. Fines and late fees can be a huge burden for some.
2. Disadvantaged communities may bear the brunt.
3. It can seem like a money grab (or actually be one).
4. Safe road design is also important.

When someone is hit by a car, says @kmralph on @freakonomics, we often ask: What were they wearing? Where were they crossing?
But if we focus on drivers, we see that while they hit 284 people in Edmonton one year, they hit 5,500 other stationary objects. https://freakonomics.com/podcast/why-is-the-u-s-so-good-at-killing-pedestrians/

Traditionally, speed limits were set based on how fast the top 15% of drivers travel. State agencies in Minnesota, Massachusetts, Washington, and others are leaning into new approaches that prioritize safety and speed management. https://ssti.us/2023/05/30/state-dots-are-helping-locals-set-lower-speed-limits/

On Twitter, @boenau points out the AASHTO Green Book is more flexible than some road designers seem to think. https://twitter.com/Boenau/status/1661335068063809536
But a 2010 article found:
30 states require wider lanes than in the Green Book.
9 require a larger minimum turning radius.
12 require design speeds 5-10mph above the speed limit. https://t.co/kRBLdd5hYZ
Chicago reached a deal with the IDOT to use design vehicles smaller than 65'. https://www.illinois.gov/news/press-release.25918.html

Australia’s rising road toll
“Data shows an increase in #speeding and running red lights in NSW and Victoria. ‘People have less patience with #traffic now after the #roads were much quieter for years.”“There were 1,204 deaths on Australian roads in the 12 months to 31 March, an almost 6% increase. Of the total deaths, 557 were drivers, up 2.2%, while 189 were passengers, up 3.8%. #Pedestrian deaths increased by 22.6%, rising to 163, while motorcyclist deaths climbed 7% to 246.”
“People in regional Australia were almost five times more likely to die in road #crashes than those living in cities last year, the latest statistics show.'
“#Children involved in a fatal crash are eight times more likely to have been struck by an SUV than a standard car.”
“The exponential rise in freight truck and heavy vehicle movements has far outstripped population growth.”
Reduce #RoadFatalities> “Design roads to appear riskier, which would slow down traffic and force users to consider each other. As driving becomes automated and requires less constant attention, it has de-skilled us as drivers.”
#Infrastructure for #walking and #cycling would help. Meanwhile, #Bellingen widens country roads..https://www.theguardian.com/australia-news/2023/may/21/australias-rising-road-toll-how-the-pandemic-and-a-love-of-big-cars-are-putting-lives-at-risk

A major proponent of #sharrows in the 90s says, “I was wrong.”
“Simply put, sharrows don’t do what we hoped they would. Studies back up that claim.”

This article is spot on. I only took one Transportation Engineering course in my undergrad program.
My masters program was much better, including a Sustainable Transportation course by Norman Garrick that completely changed my thinking.

At #TRBAM Carlos Braceras, head of the #Utah DOT, says a project’s Purpose & Need should look beyond movement and safety for cars. He mentions four pillars: 1) improve health, 2) connect communities, 3) provide mobility, 4) help economy.
He also mentions the I-15 EIS process, which is an impressive effort. https://i15eis.udot.utah.gov/

It's not that #AdvisoryBikeLanes won't work in the US. It's that we won't implement them in a way that would work. Just like so many other #RoadDesign ideas that we try and copy from Europe without actually understanding or definitely not embracing the contexts in which they work.

Bad #RoadDesign is responsible for far more crashes and deaths than it gets blamed for. But sometimes it really is just crap driving that gets people killed, even when the #infrastructure is decent.
IDK...how do we get drivers to care?
