Are you wondering how to take CAVs into account when developing airport landside traffic flow simulations? 🤔 We got you covered! 😉 Find our guidance at this link: https://nap.nationalacademies.org/read/28600/chapter/22. 🚗 Then read our Philly application example: https://nap.nationalacademies.org/read/28600/chapter/8. ✈️

SFMTA came back and made an attempt at clarifying their weird attempt at one quarter of a Dutch junction.
It's better, but that's not saying much. And the rubber marks on the bike-only side tell me some other cyclists might have a harsher opinion than this.

Have you heard of the concept of #ForgivingDesign?It comes from #TrafficEngineering and is a principle to forgive the errors of users/operators of motor vehicles.
Our built environment is designed to reduce risks and make operation of cars safe, independent of the operator’s expertise or skill.
This explains lane-departure alerts, off-ramp embankments, and even anti-lock brakes.
Highly recommend #StrongTowns if you’re on the road.

What's going on with these clusters of "unsafe backing" crashes around our courthouse?
Is this a sign all the angled parking should be switched to "back-in"? The most straightforward cause would seem to be people backing into the intersections from angled parking.
Maybe some could be from delivery trucks parked in the street? Not sure why they would be backing up though. Seems like they stop, unload, roll forward.

In #PavedParadise, @henrygrabar reminds us that several ITE leaders have denounced how its parking demand estimates have been used.
“We expected you to be smart!” says one former VP.
“Nobody on the ground knows ITE has changed their tune,” adds Daniel McKenna-Foster.

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.

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

FHWA just published preliminary VMT numbers for 2022. Americans drove slightly more than the previous year, but still less than before the pandemic. Interestingly, traffic delay was still around 50% lower than pre-pandemic, according to INRIX. https://ssti.us/2023/03/06/americans-are-still-driving-less-than-before-the-pandemic/

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/

#2 The value of travel speed is not often what we think
Investments aimed at moving traffic faster have some benefits, but new research suggests increased speeds don’t offer the same benefits as shorter travel times. As societies become more prosperous, speed becomes less important and bears very little relationship to overall time spent traveling.
