Bicyclist Killed In Hit-And-Run

A 23-year-old bicyclist was killed by a hit-and-run driver Sunday near the MSU campus. Here’s a report from KSMU, including an interview with me. Here a Google Earth look at the intersection (click for larger image). That’s a look from roughly the perspective of the west-bound bicyclist looking toward south-bound traffic. The sight lines are […]

The Heart of the Matter

Note: Nothing new to read here — just thinking out loud and boiling things down. The rules of safe movement are these: First come, first served. Drive on the right. Pass on the left. Everything should follow from these rules. Everything includes (but is not limited to): Traffic laws Traffic controls Engineering of streets and […]

Flip-side of the Amsterdam Coin

The damned thing is done. Sort of. It’s not what I had originally intended. Last year, when I published a tongue-n-cheek trailer for this video, I was planning a documentary about bicycling in Springfield, Missouri with comparisons to Amsterdam (realizing, obviously, that such comparisons are difficult at best given the radically different contexts). The comparison […]

On Paying Attention

So there I am this morning stopped at the light at Elm and Kimbrough heading east toward MSU. I’m first in line. The switch at this intersection often doesn’t trip for bicycles. There was very little traffic. A guy in a minivan pulls behind me — and we wait. After a bit, I decide to […]

Lane Position and the Sun

Hit from behind is the rarest of car-bicycle collisions in urban areas. The general rule of thumb is: The danger is in front of you at intersections. This picture, however, illustrates, a situation where the danger is behind, and the proper choice of lane positioning is not intuitive for many people. Another general rule of […]

Ol’ Time Traffic Engineering v. People

Here’s the conclusion: The 20th-century model of traffic engineering is not only outdated, but is also downright hazardous to public health and economic development. Every year, communities around the world are demonstrating that there is another way. Treating a community’s streets like a sewage system that flushes cars through quickly and efficiently has been a […]

Where Can (Should) You Ride?

Here’s what Missouri law states (307.190): Every person operating a bicycle or motorized bicycle at less than the posted speed or slower than the flow of traffic upon a street or highway shall ride as near to the right side of the roadway as safe, exercising due care when passing a standing vehicle or one […]

I Like To Watch And Listen

Every now and then I like to go to YouTube and watch traffic crash videos. You’ll find plenty of them because many people in Russia (and a few other countries out that way) run dash cams — I assume for insurance reasons. The following video is typical: You can also find many videos showing pedestrians […]

On The Showing Of Photos

What does it mean to show a photograph of a poorly-designed bicycle lane? Recent chatter from the lane-painting wing of bicycle-advocacy-land has taken the publishing of such images to task for the oft-imagined sin of over-generalizing about all bicycle infrastructure. For a good example of this, just read my post from yesterday. Let’s re-visit a […]

Don’t Be Mad At Me

I know nothing about psychology beyond the introductory class I took in college in the 1970s. That said, and given the discussion in my post yesterday about the psychology of motorist anger, I want to propose this: People, in general, do not like being the focus of anger. I believe, with nothing more than anecdotal […]

Of Motorist Rage and the Free-Rider Bicyclist

The BBC published an interesting column yesterday about the psychology of motorist rage toward bicyclists. The upshot is that, apparently, motorists are upset most because bicyclists are free-riders in traffic: they do not pay for the system, and many do not follow the rules. Here’s the money quote: So now we can see why there is […]

Of Goals and Point of View

Long-time Carbon Trace reader Robert (also a professional bicycle advocate and educator) asked this question in the comments to my post on the recent deadly right-hook crash in Boston: Do you think that bicycle facilities can be designed in such a way as to eliminate the dangers and delays? My short answer: No. He was […]

Where The Danger Is

So you’re riding along in bicycle lane thinking you’re safe because, well, isn’t that what we’re led to believe? Isn’t that why bicycle lanes are painted in the first place? They are not painted to solve any traffic problem that exists, i.e. help the orderly and safe flow of traffic according the well-establish rules of […]
