The following slides were recently reposted by Dan Gutierrez on the Cyclists are Drivers Facebook site he moderates after I posted a request there. They are from the comprehensive copyrighted presentation Dan originally posted on-line (which can now be viewed here: Old Road I (now TS101) Introduction).
This material is a small part of the groundbreaking work produced by Dan Gutierrez and Brian DeSousa.

The slide below was posted by Dan in response to a reference to the non-visual Five Layers of Bicycling Safety. This is the final slide in a five-slide series which he posted, followed by a detailed explanation:

Dan Gutierrez: The important talking point about this diagram is that the layers are cumulative and build upon each other, with the first 4 to eliminate crashes, to hopefully NEVER reach layer 5, which is only useful AFTER a crash occurs. The main motivation for making this diagram is to show that bicyclist skill development is the 1st through 4th lines of crash avoidance, and that helmet use does NOTHING to avoid crashes, but is useful if a crash occurs.

I spent a lot of time working on this diagram to get the right look and feel for the colors and sizes so it would look like a buildup.

In light of my increased knowledge today versus 2007, I might be tempted to color the 5th layer a shade of red and the 4th layer yellow or orange, to emphasize that they are reactive, vs the proactive first three layers.          [My emphasis.]

Below are Dan Gutierrez’s five slides titled Integrated “Skill Layers” after I edited the colors of the 4th and 5th layers to reflect Dan’s current views noted above. In addition, Dan pointed out subsequently that these five slides precede a sixth slide with a pie chart titled Skill Layers Cut Crash Causes, showing which skills remove which crash types.

Dan Gutierrez: Layer 3 – If you look at Cycling Savvy, it embraces elements of this layer, which were not a key focus of Bike Ed at the time. I see Cycling Savvy as the refined end product of the curriculum basics Brian and I were trying to persuade the League to embrace. I’m glad that Mighk and Keri created a real program that teaches these lessons. Note that transitions between control and sharing is now referred to as control and release (and re-establishment of control) in CS.

Skill Layers 5b

Note that the last layer is “Injury Reduction.” When all the other layers fail the danger of injury can be mitigated by wearing a bicycle helmet and cycling gloves. But this should not be treated as the first line of defense, contrary to the U.S. emphasis on helmet wearing and mandatory bicycle helmet laws that reinforce this view.

This material was created by Dan Gutierrez and Brian DeSousa after they had perfected helmet-mounted videotaping when bicycling on-road. Dan and Brian founded Dual Chase Productions, LLC, to promote their extensive on-road taping of each other when riding close together in line. As part of that effort they produced and sold a CD called Integrated Traffic Cycling ™ dated June 10th, 2007.

Later, Dan and Brian published updated and expanded information on-line, some of which can be found on Dan’s Facebook page at Old Road I (now TS101) Introduction as noted above. They have unique backgrounds which contributed to the value of this material, as shown in the first slide below, which is actually the last in the above series.

The second slide below states John Forester’s “Integration Principle,” illustrated in slides 3 and 4 which follow it.
