Our historic buildings come from an era when our cities were far denser than they are today. It is not enough to preserve buildings simply because they’re beautiful or historic or architecturally significant. We must revive them and bring them back to life. Otherwise, our cities will be little more than building museums.

Density is an Historic Resource by Bill Lindeke. This is great.

I accidentally took two photos of the Minneapolis skyline from the same spot, seven months apart. So I mashed them up.

Look at what my friends can do!

Check out MNKINO, an excuse to make a short video and show it to people, and Composer Quest, a podcast about making songs. They’re both local, organic, and sustainable.

It’s legal for suburban teenagers to drive, so I have to share the road with these people.


MPR’s headline: Minneapolis drivers see slight increase in congestion due to bike lanes

The original Fivethirtyeight headline: Bike Lanes Don’t Cause Traffic Jams If You’re Smart About Where You Build Them

You really shouldn’t conflate “congestion” and “street use.” If more people use a street without harming each other, that’s a good thing. Congestion only happens when the volume of traffic approaches the street’s capacity and the throughput declines. (Throughput is the number of things that move past a point in a channel per unit of time.)

There’s a really good part of Traffic by Tom Vanderbilt where he describes the throughput of a highway approaching rush hour. Before rush hour, cars are going 70mph, and they’re pretty spaced out. Throughput is 10,000 cars per hour. At the beginning of rush hour, it’s starting to get busy. The speed of traffic has declined to 50mph, but because traffic is denser, the throughput has actually increased to 12,000 cars per hour. At peak traffic, though, fender-benders and lane-changes have ripple effects that slow everyone down a lot. The speed has declined to 35mph and the throughput is just 8,000 cars per hour.

So from a holistic perspective, the optimal use of scarce road space is just after cars have to slow down a little, right before you reach capacity. That’s the sweet spot when you’re facilitating the most human activity with an expensive resource. Up until then, you’re just wasting money and space.
