The US Is Counting Traffic Deaths Wrong By emphasizing the number of people killed per mile rather than deaths per capita, traffic safety groups risk normalizing the factors that make American roads so deadly.

β€œMeasuring deaths per mile lowers the ceiling on what even the best-crafted safety strategy can achieve. Yes, building less dangerous cars and more forgiving roads would help... But another way to save lives deserves far more attention than it gets: Stop forcing Americans to drive so much.”

At ~$1 billion/day, the US has spent as much on the war in Iran in ten days as the entire FY25 budget for the National Science Foundation ($10 billion).

Trump's FY26 budget request for the agency declined to $3.9 billion, due to a "realignment of resources in a constrained fiscal environment."

β€˜Flying Cars’ Will Take Off in American Skies This Summer The federal government announced a new pilot program designed to get new kinds of ultralight vehicles and β€œeVTOLs” up and running around the countryβ€”even if they’re not fully FAA-certified.

We already have an epidemic of cars hitting people and buildings, sometimes intentionally as weapons of terror. So explain to me how flying cars will work without TSA-level security to prevent someone from flying one of these into my house or my children's school.

From historical maps to lived experiences: A community-engaged approach to 3D urban modeling of neighborhoods prior to urban highways and urban renewal

The latest publication from the Ghost Neighborhoods project where we are generating 3D urban models from historical Sanborn fire insurance maps. These maps exist for 12,000 places across the USA for the period 1880s-1960s. Our techniques - including community engagement - can be applied widely

Why changing speed limits in Ohio is harder than you think | Getting There Changing Ohio's speed limits isn't as simple as a phone call. Learn why a formal study is required and how it impacts road safety.

Are there any studies to support this? I know traffic engineers believe this, but traffic engineers believe a lot of things that vary from theory and evidence:

Sometimes lowering the speed limit might make roads more unsafe, not less, ODOT spokesperson McGuire said.

Study: Most Of America's Paint-Only Bike Paths Are On Our Deadliest Roads β€” Streetsblog USA Even worse, most Americans see these terrible lanes and think, "I'd be crazy to ride a bike" β€” and the cycle continues.

Most American "bike lanes" are little more than lines of paint at the edges of deadly roads β€” and that lack of protected infrastructure is keeping many would-be riders out of the saddle, a new study confirms.

Whether you use it or not, better public transit makes your commute better A surprisingly small drop in cars on the road can dramatically ease congestion, and public transit is one way to get there.
