The City of Sacramento is soliciting comments on its Interstate 5 / Richards Boulevard Interchange Project. Please take a look and comment. My comments are summarized as: The safety justification doesn’t hold water. The interchange itself has no fatal collisions and no severe injuries during the period of time analyzed (safety starts at about 9:56 […]

The City of Sacramento recently release a new 311 app. I have been using this app (iOS version), mostly to report issues with construction signing. The app is broken! What are the issues? If you switch away from the app to some other app, the app logs you out, and you have to log in […]

Thanks for the website Mapping Inequality: Redlining in New Deal America, I have better copies of the Sacramento redlining map, which was produced in 1937 by the Federal Home Loan Bank Board and the Home Owners Loan Corporation (HOLC). These were government sanctioned zonings meant to guide banks to only loan to certain kinds of […]

The 2017 video, Why We Cycle, was offered for free streaming for one day, yesterday. Though the freebie is over, I highly recommend you watch the video; at $4.99 it is still a great deal. This video has brought joy to me in ways that I haven’t felt in a while, and I think it […]

The last month has brought an awareness to many people about what essential is. I doubt if you asked people in January who the essential workers are, you would have gotten an answer that matched who turned out to be essential. I probably would have missed most of them. It is not the rich, or […]

I have long been interested in access to parks, what the availability of parks is to people, and wanted to map this. It is just today that I was finally able to start doing this. I acknowledge the support of the Sacramento Area Council of Governments (SACOG) GIS staff, without which I could not have […]

We can’t go back to the way things were before! To the car-dominated world where walkers and bicyclists were considered second-class citizens, worthy of consideration only when it did not inconvenience the privileged drivers of cars. The streets are largely empty (except for some essential drivers and too many joy-riders). The air is clean. The […]

Maps have suddenly become the preferred method for presenting information, which is a good thing. But I see so many maps that don’t present what they are claiming to present, or supporting the story being told in the text. Ack! Since coronavirus maps are the rage, I’ve selected two to show. These are from the […]

The Manual for Uniform Traffic Control Devices (MUTCD), and the California equivalent, are standards for the design and placement of traffic control signs. They have the force of law for any federal or state funded roadways, but there is no enforcement mechanism, so signs that do not meet these standards can certainly be found, both […]

Now, on to why I brought up the topic of prudent drivers. A prudent driver on a two lane (one lane in each direction) roadway largely controls the behavior of irresponsible drivers. On wider roads, with two lanes or more in a direction, whether a one-way or two-way, the irresponsible driver can do as they […]
