Morning Links: LA raises speed limits, Vision Zero holds course, and LA River Bike Path reopens in Long Beach

One quick note. Come back after 11:00 this morning for a guest post from Derrick Paul about the planned Vision Zero lane reduction and complete street project on Temple Street. 

And why it hasn’t happened.

………

Los Angeles will be raising speed limits on nearly 100 miles of streets to comply with California’s deadly 85th Percentile Law, which allows drivers to set speed limits by applying their foot to the gas pedal.

Meanwhile, speed limits will decrease somewhat on a little more than 52 miles of streets.

The tradeoff is that police will now be able to use radar to enforce speeds, which they had been banned from doing on nearly 80% of LA streets.

Under the terms of the law, police can’t use radar to enforce the speed limit if a street hasn’t had a speed survey within the last seven years.

Once the survey is conducted, the speed limit must be set at the speed driven by the 15th fastest motorist driving unimpeded in non-rush hour traffic, although the city does have the option to round down slightly.

So in order to make our streets safer, we have to make them faster and more dangerous.

Or just repeal a stupid, outdated and deadly law.

Correction: In my haste last night, I mistakenly wrote that the 85th Percentile Law was based on the average speed of 85% of motorists, ignoring my gut feeling that I was wrong, but too tired to stop and look it up.

And I was right. That I was wrong, that is. 

The following email from Casey Kerrigan clarifies this complicated law better than any other explanation I’ve seen. 

When doing the speed survey the speed limit is based on the 85 percentile not on the average speed of 85% of the cars surveyed.  Note that speed surveys are conduced under the optimal conditions to speed, ie during the day, at a non rush hour time and only the speed of free flowing cars are measures. Free flowing are cars with no traffic ahead of them for at least 5 seconds on a straightaway and unmarked cars are used to house the speed measurement equipment.
This is from the Caltrans guidelines for how to set speed limits which you can find here.
This paragraph is taken from the Caltrans guidelines linked above on page 36.

3.2.6 Calculating 85th Percentile Speed

If 100 vehicle speeds are plotted, the 85th percentile speed is determined by looking at the speed of the 15th vehicle down from the top speed. Fifteen percent of the vehicles are travelling faster than this speed, and eighty five percent are travelling at or below this speed. If less than 100 vehicles are counted, the 85th percentile speed must be determined by calculating 85 percent of the number of vehicles counted and determining the vehicles’ 85th percentile speed. For example if 70 vehicles were counted, 0.85 x 70 = 59.5. The speed of vehicle 60 represents the 85th percentile. Examples are shown in Appendix A on the Speed Zone Survey Sheet examples.

Speaking of which, Vision Zero Los Angeles has released their 2018 Action Plan & Progress Report.

The city plans to remain on course with the program, despite a sharp jump in pedestrian deaths, and badly missing Mayor Eric Garcetti’s goal of a 20% reduction in traffic fatalities in 2017.

Of course, that was overly ambitious, since the program is just now gaining its footing and getting its first real funding.

The LA River Bike Path has reopened in Long Beach, where it had been closed for construction work, now that a large construction crane has been removed.

However, work vehicles and flaggers will remain on the path, and riders may be required to slow down or walk their bikes through the construction zone.

Thanks to Long Beach Mobility and Healthy Living Programs Officers Michelle Mowery for the heads-up.

Great idea, as a Washington bike school teams with a woodworking school to teach everything from wrenching to wood frame and wheel building.

Evidently, LA drivers aren’t the only ones who complain about removing traffic lanes from massive streets. Tempe AZ will restripe a roadway to remove bollards protecting a bike lane and add back a third traffic lane in response to motorist complaints.

You’ve got to be kidding. Just days after the Utah house approved an Idaho stop law, a bill that would allow drivers to also treat red lights as stop signs passed a legislative committee. After all, what difference could there possibly be between someone on a 15-pound bike and someone wrapped in two tons of high-speed glass and steel? I mean, other than the bodies the latter would likely leave behind?

The war on cars may be a myth, but the war bikes is all too real, as Aussie bicyclists find thumbtacks spread across at least four popular riding routes. Far from a harmless prank, something like that can cause serious injuries — or worse — if a flat causes a rider to fall. And should be prosecuted as such.

The government of Queensland, Australia, has introduced a presumed liability bill, which would presume that the operator of the more dangerous vehicle has a greater responsibility to avoid crashes, and would be considered at fault in a collision; the head of the local auto club calls it a divisive bill that pits motorists against cyclists. Actually, motorists have done that themselves for decades.

Morning Links: Expanded mobile phone driving ban, Vision Zero speed limits, and scary bike-riding non-clowns

The good news is, we’ve figured out what caused the problem with email notifications for new posts. Now that the tech supports are back from their annual conference, maybe we can get it working again.

………

Governor Jerry Brown signed legislation prohibiting drivers from holding and operating mobile phones for almost any reason, including changing a play list or using a GPS.

However, in a sign of just how seriously the state doesn’t take distracted driving, the fine for the first violation is a measly $20, rising to a whole $50 for subsequent violations.

Even though distracted driving is every bit as deadly as drunk driving.

And people will continue to die until we treat it that way.

………

Seattle votes to lower speed limits on city streets, from 25/30 mph to 20/25 mph as part of the city’s Vision Zero plan.

Which is exactly what LA has to do if there’s any hope of reducing, let alone eliminating, traffic fatalities by 2025.

Yet here in the City of Angels, the case is complicated by streets with near-highway speeds as a result of the deadly 85% rule, which sets speed limits at the average speed of 85% of drivers on any given street.

In other words, the best way to make sure the speed limit goes up is to keep your foot firmly planted on the gas pedal. Which is kind of like putting bank robbers in charge of bank security.

Never mind that speed limits are unenforceable by radar guns on roughly 75% of the city’s streets, thanks to the city’s failure to conduct the required speed surveys.

And never mind that decades of flawed traffic planning has left Los Angeles with countless streets engineered to carry traffic at speeds far beyond the posted limits, and too many drivers more than happy to take advantage of that.

Angelenos have gotten used to driving that extra 10 to 15 mph above the speed limit, even on streets with posted limits of 45 mph or more.

We could see open rebellion and riots in the streets if the police started cracking down on speeders — or at least a number of recall threats and angry letters to the Times. Let alone if city officials found a way around the 85% law to lower limits to life-sparing levels.

But it has to be done.

Because until we do, Vision Zero will be nothing more than a couple of words.

Maybe the national obsession with scary clowns is just a tad out of control.

Consider this report from Portland, Tennessee about the arrest of pranksters posing as clowns.

State and local police urge residents to call in all unusual behaviors to the nearest law enforcement agency. The warning comes in light of several incidences in Tennessee and beyond involving people disguised as clowns who have threatened and scared people and children…

Portland (TN) police received another call Tuesday morning reporting a clown was riding a bicycle near Highways 109 and 52. The report was false and police found a person riding a bike wearing a safety vest with flashing lights to warn traffic, Heavner said.

Charge filed in death of bike-riding Cal Poly Pomona student Ivan Aguilar; is the university really at fault?

A bike-riding college student is dead.

The driver who took his life faces a relative slap on the wrist.

And the campus where he was killed appears to be doing little or nothing to protect cyclists on campus.

Instead, Cal Poly Pomona seems to be hiding behind California’s devastating 85th Percentile Law to justify plans to raise speed limits on campus, making it even more dangerous for anyone on foot or two wheels.

Or at least, that was the gist of a Twitter conversation I had with representatives of the school Wednesday morning.

The outpouring of grief that followed the death of Cal Poly Pomona student and cyclist Ivan Aguilar should have spurred immediate action to tame what is reportedly dangerously out of control traffic on campus, where numerous students have reported feeling unsafe walking or biking.

Yet four months later, no changes have been made to protect students and faculty — not even on the street where Aguilar lost his life. And none are currently planned.

In fact, the school’s new 2013 traffic study doesn’t even include the words bicycle, bicyclist or pedestrian, according to a story by Beau Yarbrough in the Daily Bulletin.

Kind of makes it hard to make meaningful improvements when nothing is considered except speeding motor vehicle traffic flow.

Although to be fair, they have talked about bikes.

Key word being, talked.

But traffic plans that don’t even consider non-motorized transportation show just how out of touch campus leaders are. And how far the school has to go to make it safe for anyone, let alone everyone, whether on two feet, two wheels or four.

Apparently, those students are right to be afraid.

Especially when the death of a popular and promising young man leads to nothing more serious than a misdemeanor charge with a maximum penalty of just one year in county jail.

According to the Daily Bulletin, CPP Civil Engineering student Gonzalo Aranguiz Salazar will face a charge of misdemeanor vehicular manslaughter without gross negligence.

In other words, pretty much the mildest charge authorities could file under the circumstances, while still holding someone accountable for the death.

Is that justice?

I have no idea.

I’ve yet to see any description from any source of how the collision occurred. No word whatsoever on how fast the driver was going, or if he broke any traffic laws leading up to the impact with Aguilar.

Apparently, it’s on a need to know basis.  And no one with knowledge of the investigation seems to think you or I need to know.

We’re just expected to accept that the charges are fair and appropriate given the top secret circumstances.

Sort of like we’re supposed to trust that campus administrators have the safety of their students at heart, on a campus that does not include a single inch of bicycling infrastructure.

Beverly Hills, meet your collegiate counterpart.

In all honesty, I’m not sure Salazar is the one who should be facing charges.

But you can’t charge a college with living in the auto-centric past and favoring motorists at the expense of every other road user. As much as it may be deserved.

But something tells me Cal Poly Pomona won’t make the list of bicycle-friendly universities anytime soon.

Update: Gottobike forwards a quote from American bike racer Ted King that seems oddly appropriate to this discussion:

It is impossible to find solutions when you’re busy making excuses.

And Boyonabike reminds me of something I let slide from the Daily Bulletin story about the Salazar charge, and shouldn’t have. 

The story quotes Megan Chaney, director of Clinical Programs and Experiential Learning and Associate Professor of Law at the University of La Verne College of Law, explaining why a misdemeanor charge may be appropriate in this case.

“A lot of time when somebody plows into somebody in a crosswalk or an intersection, it’s just an accident,” Chaney said Wednesday. “We put the onus, the responsibility on the driver, not the pedestrian, unless they’ve done something really horrible….”

“You’re allowed to look at the radio; that’s why you’ve got a radio. You drop your water bottle and look down to pick it up,” she said. “You really weren’t acting with any sort of criminal culpability. “

That’s the problem.

As a society, we’ve chosen not to hold drivers responsible for all but the most extreme actions behind the wheel. The collisions that result from carelessness, distraction or relatively minor violations of the law are excused as mere accidents, and left for the insurance companies to deal with, with little or no consequences for the drivers involved.

And that’s why we continue to have 30,000 +/- deaths on American streets each year.

It may be the current legal standard. 

But actions that result in the death or serious injuries of others should never be accepted. Or excused. Motor vehicles are, by their very nature, dangerous machines, and their operators can and should be expected to use the same caution behind the wheel that we expect from those involved in any other hazardous situation.

When life is taken more seriously than simple convenience on our streets, then — and only then — will anyone be safe on our streets.
