Documenting near misses

[smbi...@earthlink.net]

I urge all of you to watch this video .  It demonstrates how to use an incredibly useful data collection tool for near misses.  As you all know, near misses never get into documents used by public policy makers to determine how safe or dangerous a street or intersection is.  Armed with near-miss data, advocates can get the attention of policy makers, even sometimes law enforcement.

 

Stay safe,

Is this being used by cyclists in the Solana Beach area where the stupid Class 4 has increased falls and injury exponentially?

Hi Pete. What is a Class 4? I've never heard of the term.  

Best, Damian

A Class 4 bikeway is separated from travel lanes by a vertical curb, bollard, planter, parked cars etc..  “Cycle Track”

Class 1 is a bike path, 2 is a bike lane, 3 is a bike route designated road

Oh, Class 4 bikeway. Right. Well familiar with those. I thought Pete was talking about a new e-bike term that was starting to be used -- Class 1, 2, 3 and now 4 (??) e-bikes. (LOL) 

Thanks!

Thankfully, there is NO such federal or any state definition of a supposed Class 4 (it's just some people's attempt at humor or to be clever)! CVC 436.1 and this bill by Senate Blakespear, SB-1167 will finally end that nonsense once and for all!!!

In CA a "separated bike lane" or Cycletrack is technically a Class 4 bikeway. Segregation.

A correction that may help us in the future regarding bikeway classes and electric bicycle classes. Bikeway classes use Roman numerals. Electric bicycles use Arabic numerals. 

Here's what Gemini provided.

 The California Highway Design Manual (HDM), specifically within Chapter 1000 ("Bicycle Transportation Design"), defines and describes the four primary classes of bikeways using Roman numerals.

According to the HDM and the California Streets and Highways Code (Section 890.4), the classifications are:

Official California Bikeway Classifications

• Class I Bikeway (Bike Path): Provides a completely separated right-of-way for the exclusive use of bicycles and pedestrians, with cross-flow by motorists minimized.

• Class II Bikeway (Bike Lane): Provides a striped lane for one-way bike travel on a street or highway.

• Class III Bikeway (Bike Route): Provides for shared use with pedestrian or motor vehicle traffic and is identified by "Bike Route" guide signs.

• Class IV Bikeway (Separated Bikeway): Also known as a "cycle track" or "protected bike lane," this is for the exclusive use of bicycles and includes a required physical separation (such as grade separation, flexible posts, or barriers) from through vehicular traffic.

---

Important Context

• Hierarchy: The HDM explicitly states that these designations are not a hierarchy (i.e., Class I is not inherently "better" than Class II); rather, each class is chosen based on the specific needs and constraints of the roadway.

• Evolution of Class IV: While Classes I, II, and III have been in the manual for decades, Class IV was officially established more recently following the Protected Bikeways Act of 2014.
