Florida's 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. freakonomics.com/podcast/why-i

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. ssti.us/2023/05/30/state-dots-

On Twitter, @boenau points out the AASHTO Green Book is more flexible than some road designers seem to think. twitter.com/Boenau/status/1661

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. t.co/kRBLdd5hYZ

Chicago reached a deal with the IDOT to use design vehicles smaller than 65'. illinois.gov/news/press-releas

“The exponential rise in freight truck and heavy vehicle movements that has far outstripped population growth.”

You know about "induced demand", where you build or widen roads/highways and then you have more cars, more congenstion it just keeps filling up with cars it never ends? WELL! Allow me to introduce to you "traffic evaporation" in which you make the car traffic GO AWAY, POOF! GONE! How? Make transportation better for other kinds of traffic!

This article is spot in. 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.

"To create a Vision Zero plan in Maine, GPCOG hosted four public forums last fall drawing roughly 100 people. An online survey has generated 150 responses, and people have marked 120 “hazards” on a map of area roads. The agency hopes to gather more feedback in the coming weeks to inform a draft report that will go to the Portland Area Comprehensive Transportation System board for approval."

At Carlos Braceras, head of the 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. i15eis.udot.utah.gov/

It's not that 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 ideas that we try and copy from Europe without actually understanding or definitely not embracing the contexts in which they work.
