“For every mile they transport a person, they are also driving around empty”: Here’s a puzzle. S.F. is one of our most walkable and transit-friendly cities … and yet auto congestion there is worsening. Why? Some point to ride-sharing services and, now, Waymo. Is it time for an urban congestion fee? https://www.sfchronicle.com/sf/article/traffic-congestion-walkable-22403512.php

The “Grand Plan”: Atlanta is crisscrossed by freight train lines. But what if the state gov’t helped railroad companies bypass the city entirely? The state’s price for helping the railroads could be control of the urban lines that are no longer needed. And what could this mean? A vast expansion of rail #transit. https://saportareport.com/vision-to-dramatically-increase-passenger-rail-in-metro-atlanta/columnists/mariasmetro/maria_saporta/

E-bikes are how we will change mobility in cities by getting people on two wheels who wouldn’t ordinarily try #cycling. But we must regulate e-bikes because hospital ERs are filling up with children with traumatic brain injuries. Ask the doctors: This is not a problem among adult riders … it’s teens. https://www.wbur.org/news/2026/08/19/bikes-injuries-deaths-scooters-massachusetts-pedestrians #publicsafety

“GET OUT OF THE WAY!” There are problems that cities should aspire to. Here’s one: Your bike trails are so crowded that the behavior of a few becomes a problem for the rest. This is a reason we have local gov’ts. They can set rules for people to enjoy places … while not thinking they own them. https://www.phillymag.com/news/2026/08/13/aggressive-cyclists-philadelphia/ #cycling

Will Zohran Mamdani be a successful mayor of NYC? Well, tough job and some of his promises were unrealistic, so it’s too early to say. Still, he should get universal acclaim for appointing Janette Sadik-Khan to NYC’s #transit board. Who is she? She’s the one who began a transformation of NYC’s streets 20 years ago … and wrote a book about it. https://nyc.streetsblog.org/2026/07/30/q-and-a-new-mta-board-member-janette-sadik-khan-yaps-with-streetsblog

“Twenty is plenty”: E-bikes could be a game changer for urban #mobility, cause millions who drive to try #cycling for short trips … including the elderly and those with physical impairments. But for this, we must make e-bikes safe.

Dunno. There are ways of measuring congestion (NYC has transponders on taxis so it can see how long trips take.) Others use cellphone data. So it's knowable, but I don't think the impact on congestion by Waymos is yet known.

#Solar power flips the business model of utility companies on its head. Fossil fuels are expensive to extract and transport but the power they generate travels over long-amortized infrastructure. So, fixed costs small, variable costs high. Solar has big upfront costs for homeowners, but from that point on, energy is essentially free. This terrifies #utilities. https://www.nytimes.com/2026/07/21/upshot/solar-panels-prices-batteries.html

Most cities are located on rivers, and if they are inland cities, those rivers probably have dams. They were built to power mills in the days before electricity. Bottom line: They aren’t needed today. Now cities like Mpls are considering … should we remove these dams and restore the river to its natural flow? https://www.mprnews.org/story/2026/07/02/what-would-removing-twin-cities-locks-and-dams-mean-for-the-mississippi-river

A decade ago, a British think tank produced a study of how people meet and do enjoyable things together … like play bingo or join amateur rugby clubs. (It was titled “Clubbing Together.”) Why should we care about such things? Because urbanism is about connecting people. And casual connections can lead to civic involvement. https://www.nytimes.com/2026/06/29/nyregion/nyc-lonely-making-friends.html

Cars cause many problems in cities, one of which is their voracious appetite for #parking, which raises costs for all. But here’s something you haven’t considered: Vehicles are getting so big that they almost cannot fit into conventional parking spaces. Typical space: 18 ft deep, 7.5 to 9 ft wide. Ford F-150: 19 ft long, 8 ft wide. https://www.ajc.com/news/2026/06/are-cars-getting-too-big-for-atlantas-parking-lots/

S.F.’s #transit systems saw a huge exodus of riders during Covid. Just as officials despaired this was permanent, something odd happened: Riders are returning. Why?

Why nobody liked Lindsay: NYC salutes its most cherished heroes with parades along Broadway. There will be a first-ever parade today for the NBA champions, the Knicks. But wait.

Urbanists should take a deep breath when states regulate e-bikes by setting speed limits and age restrictions. It isn’t always an attempt to rein in alternatives to driving.

It costs $11 million or more to build a single mile of a six-lane highway in the most urban areas, not including land costs. Mpls has nearly 100 miles of bike lanes along its streets plus an equal amount in off-street trails. In the past decade, the city spent $26 million building this #cycling infrastructure. 200 miles of bike lanes vs. a little more than two miles of highway. This is a bargain. https://www.minnpost.com/fact-briefs/2025/07/has-minneapolis-spent-billions-of-dollars-on-bike-lanes/
