Don’t Door Me!

This is an excellent article not just about dooring accidents, but about bike lane design standards, how bicycle accidents are counted and how the system continues to implement design standards that are sub-standard.

Where Bike Lane Design Collides with Savvy Cycling

National and state databases only include crashes involving motor vehicles in transport. Since a parked car is not in transport, and a bicycle is not a motor vehicle, crashes where a bicyclist hits a parked car door are excluded.


Dooring accounts for 12 to 27 percent of urban car-bike collisions, making it one of the most common crash types.

Cyclists with iPods hear the same as motorists listening to nothing

Finally, researchers have asked the question and found that cyclists with iPods or earbuds on listening to music can actually hear more than drivers and passengers inside automobiles with the windows up listening to nothing.

“We quickly established that cars are remarkably soundproof. We measured the average peak of ambient traffic noise inside the car (with the motor running) to be 54dB, which is 26dB quieter than outside the car. We rang a bike bell right outside an open car window and measured it from in the car at 105dB. With the window closed, the same bell registered just 57dB.”

BAD NEWS SHARROWS some infrastructure worse than none

From a study out of University of Colorado sharrows may actually do more harm for bicycle riders than good.

Some Bike Infrastructure Is Worse Than None at All

But far from giving cyclists a safer ride, or even doing nothing at all, sharrows might actually be doing some harm by tugging bikes into moving traffic. Some research has found they do reduce dooring (when the door of a parked car hits a cyclist). But only one study to date looked at whether or not sharrows had any impact on overall car-bike collisions—and that study found they could be increasing the risk of injury.

Walk Bike To Work Or School – Get Started

A Beginner’s Guide to Biking to Work

If that bicyclist whizzing by seems a little happier than the average gridlock-bound car commuter, you’re not imagining it: A recent study found that two-wheeled commuters were happier than their gas pedal-stomping, car-caged peers.

Becoming a bike commuter might seem daunting, but the benefits can be worth it: exercising regularly, saving money, decreasing your carbon footprint, absolving yourself of guilt over that break-room doughnut.

It is not just for adults – kids also benefit from walking or biking to school. For added safety, folks create walking busses or bike trains. October 10, 2018 was the national #WalkToSchoolDay but why not try to make that everyday?

Bicycle Helmet Testing – IIHS & VA Tech

It’s about time that bicycle helmets got more rigorously tested, say, like motorcycle helmets have for years.

Bike helmets in the U.S. are required by the Consumer Product Safety Commission (CPSC) to pass a series of tests in which helmets are struck against an anvil at a set speed. The only requirement is that the helmets prevent head impact accelerations over 300 g, a level associated with skull fracture or severe brain injury. There is no requirement for helmets to limit concussion-level forces, which are more common among bicyclists in crashes.

A few take aways: more expensive isn’t better, more coverage isn’t better.

Perhaps surprisingly to some, the “urban” style helmets that look like they cover more of the head appear to provide less protection than the sleeker road helmets, the Virginia Tech team said.

The researchers found that bicycle helmets offered different types of protection. Not all bicycle helmets protected well against concussion. Bicycle helmets also may not protect adequately for the way cyclists often hit the ground at an angle. With cyclist fatalities up 20% in the last ten years, improving and formally testing bicycle helmets is a huge step forward.

Urban-style helmets — which have nearly solid covers with few vents — and those that haven’t adopted the latest anti-concussion technology were more than twice as likely to result in injuries, researchers from Virginia Tech and the Insurance Institute for Highway Safety found in a study released Tuesday.

San Diego Vision Zero Portal

**Update July 9, 2018
While it is really great we finally have our own Vision Zero San Diego website and portal, unfortunately the data posted on launch was very misleading and greatly understated the actual fatalities in 2016 which were actually about twice as many. Mistakes like this won’t help use data to identify the main dangerous streets and improve our roads with a priority of focusing on where most people are getting hurt and killed.

According to KPBS,

The city’s webpage, which was launched in May, states there were 33 traffic deaths in 2016 and 21 deaths in 2017. Police data show the number in 2016 was actually 64 — more than twice what the webpage states — and that 2017 actually saw 35 traffic deaths.

Another section of the webpage includes three public service announcement videos produced by the city, each one stating there had been 37 traffic deaths in 2017.

To add emphasis to how dangerous our roads are, and why we need the Vision Zero data to prioritize fixing our streets, another KPBS story published June 23, 2017, “In San Diego, Cars Are Deadlier Than Guns

In pure numbers, more people die from car crashes in San Diego than are murdered. The city’s police department counted 260 traffic deaths on city streets from 2012 to 2016, and 206 murders over the same time period. Adding in the number of people who die on San Diego freeways, which are governed by Caltrans, there were more than twice as many traffic deaths as there were murders.

Chilling Report on Hit and Run Epidemic

The Washington Post had a disturbing article on the steadily increasing hit and run incidents since 2009, “Cyclists say chilling report on hit-and-run crashes points up need to redesign streets for safety.”

The AAA Foundation for Traffic Safety said in a report this week fatal hit-and-run crashes have reached the highest point on record in 2016, having increased by more than 7 percent every year since 2009. Nearly 65 percent of the victims are bicyclists and pedestrians.

Auto insurance uninsured driver / under insured (UIM / UM) coverage can help you and even your passengers with a hit and run unidentified vehicle. In addition, your auto insurance protects you even when you are a pedestrian, or riding a bicycle.

In California, your insurance company is required by law to include uninsured motorist coverage as part of every automobile policy written, unless you specifically decline it, in writing. Coverage is usually designated on the face page of your automobile insurance policy by the letter or letters “U” or “UM”.

Some insurance companies try to talk motorcycle owners into waiving UM and UIM coverage. Do not let this happen. Never waive UM or UIM coverage.
