Ever More “Speed Hump” Speed Bumps for Golden Gate Park – What’s the Recommended Speed for These Things?Thursday, November 3rd, 2016
Get up to “speed” here.
Here we go – on JFK looking east towards Transverse / Crossover
And now close to Marx Meadow looking west – this one will be going in soon:
I guess this one will go almost all the way across JFK Drive:
And, now closer to 30th Avenue, looking east – this was the first to be installed, now with a new sign:
I don’t know when I’ll make it back here with a vehicle. IMO, 20 MPH or so is prolly the limit for you. (I had my decidedly non-sporty ride mistakenly set in SPORT mode, but I don’t think it makes much difference on a road regularity as big as this, but I’ll try it again sometime on my ride’s softest suspension setting.)
OTOH, if you have a brand-new BMW M4 GTS, how about 0 MPH as the limit?
And on bikes heading west, IDK. Look out, Jack, is all I can say.
I think the actual speed limit for the bumps is 25 MPH, but that seems too fast for IRL.
Our SFMTA has reported that some drivers go 32-34 MPH on this stretch of JFK and I’m sure these numbers come from someplace real, but I’m also sure whatever stat they’d report has been manipulated for their own purposes, oh well.
On It Goes…
Here it is:
These photos are from a few days back, and this bump / hump itself prolly was installed about ten days back. If you hit this thing at 25 + you will feel it, I promise you. My ride was practically made to handle something like this bump with aplomb, and I certainly felt it. Oh, and look, a speedometer system, of sorts:
Here’s the “near term” language, straight from our incompetent SFMTA.
I’ll tell you, not a whole bunch of drivers go signif more than 25 MPH on the JFK, despite what SFGov might tell you, or imply, with their nonsensical “some traffic travels through JFK at 32-38 MPH type” of stat. Well, sure, some traffic. I go through at exactly 25 which requires a touch of braking on the downhillier parts like near Speedway Meadow. (Hellman Meadow? I don’t think that’ll take for a good long time.) Anyway, if you get on my rear bumper I’ll simply pull over, pretending to get ready to park, and then pull back in after you’ve passed me. But I don’t do that too often.
(If you wanted to decrease illegal “speeding” on JFK, you’d raise the limit to 30 MPH and, conversely, if you wanted to, for some reason, increase illegal speeding on JFK, you’d lower the limit to 20 MPH.)
Anyway, if you want to lower speeds on JFK, you’d put in a brace of speed bumps – that’ll work. Of course, there’d be the noise, vibration, and safety concerns of San Francisco voters, but that will get addressed later, one assumes…
And of course, a few speed bumps is nothing like this recent proposal.
And oh, down Mexico way, if a municipality want to have a nothingburger speed bumps like this, they’d hire somebody to do it one day and then it’d be done the next – it wouldn’t turn into an expensive half-year “project” with countless meetings and endless news releases…
IDK, maybe somebody hacked this sign to say what it says. Regardless, this is a big improvement over the 10 MPH sign it used to be just a few days back:
More changes are coming for this area, before 2017, to prevent you from using JFK the way you’re used to…
This official “SLOW TO 10 MPH” sign was up near Speedway Meadow during Outside Lands 2016, but it’s still there now long after OL’s blown town:
The limit goes back up to 25 MPH near 30th Avenue?
(This trailer doesn’t “see” bikes, AFAIK, unlike some others.)
Changes to the “access” we have to JFK are coming soon, but I don’t know what they are and if this is a part of it.
Our Presidio sometimes records license plate numbers and checks timestamps to see who’s “cutting through” the park (instead of having the Presidio as a destination in itself). The Presidio People think “Cut Through Traffic” is evil, but really, all traffic is cut-through traffic to somebody. Oh well.
If SFGov wants people to use Fulton instead of JFK, there will be some problems with that…
19th Avenue is the New Alternative to Poorly Designed and Administered Sunset Boulevard, Believe It Or NotWednesday, October 21st, 2015
Here it is, 19th Avenue in the Sunset / Parkside, with traffic going about 38-40 MPH through green light after green light in sections marked for 30 MPH:
Historically, Sunset has been the alternative to congested 19th, but things have changed lately. Of course, Sunset was a bad idea, a big wide boulevard with pointless medians up the yingyang. The question now is what to do about it.
A Tad Serious for the Panhandle Bike Path, Non? Is This a Sport or Just a Way to Get Around? – Both?Tuesday, September 22nd, 2015
IDK, how fast do you need to pedal on this downhill stretch of the Panhandle Multi-Use Trail what with the stiff prevailing tailwind and the super-light bike and the super-skinny tires?
I’ll tell you, you don’t need to pedal at all, from Stanyan to the fucking DMV (and Beyond, if the traffic signals work in your favor) – just really pump up your tires and try it sometime.
I’ll tell you, you know who else mixes up sport with transpo? The good bulk* of your BMW drivers, who cause more than their fair share of problems on our roads, despite having better-than-average reflexes and whatnot.
A good portion of your BMW car drivers need to slow the fuck down, and certain other people, perhaps you, see above, might need to as well.
That’s my point.
*Some purchase Beemers as Just Another Luxury Brand these days, of course. These people are excused…
A Backlash Against Cyclists at the Panhandle Improvement Project Open House in Golden Gate Park – Bike Path Vs. Multi-Use PathWednesday, August 5th, 2015
[UPDATE: For instance, this, from this AM.]
Well, the San Francisco Bicycle Coalition must have sent over a cadre (of its now disempowered, voteless minions) to the latest scoping session / open house / focus group for the proposed Panhandle Improvement Project what took place on Saturday.
Nevertheless, it would appear that the majority of those invited by SFGov through snail mail have a few beefs with the behavior of cyclists on the bike path / multi-use trail on the Fell side of the Golden Gate Park Panhandle.
Here’s a smattering of written comments:
In turn, one Brocephus wrote about putting in a bike lane on Oak and Fell, over and over and over:
I guess that’s a kind of parity.
The people who turned up are probably what SFGov considers The Community, when it ponders on how it spends our money, but, of course, there’s a degree of sample bias.
If SFGov conducted a poll of the actual community, it might discover a different hierarchy of important concerns.
On It Goes…
I don’t know. Some consultant came up with 10 MPH a few years back, but that idea wasn’t good for business, or something like that.
Now here’s a sign that tells you how fast you’re going, anyway:
Sometimes, I just don’t know…
Masonic is a crazy street with a crazy history. Like, 4 Masonic is more than 1000 feet away from 5 Masonic, for instance – what’s up with that? And on the other end of this street, up around the 1000 block, well, that’s where mayoral wives have lived, like Blanche Brown, you know, our First Lady up until ten years ago, the woman that most people in town weren’t aware of, and, more recently, Jennifer Newsom, who moved away to Marin just months after husband Gavin was hectoring families to NOT move to Marin County, oh well.
Anyway, there have been three pedestrian / cyclist deaths on Masonic* in recent memory, so that’s part of the reason why the SFMTA installed a pair of speedometers to tell drivers how fast they’re going.
The problem is that they don’t work very well.
Like here. Moments before, it was indicating 24 MPH, but then it jumped up to 32 MPH all of a sudden for no reason. All the cars were moving about the same pace uphill and there was no traffic traveling down the hill:
Speaking of which, the speedometer for traffic heading downhill is even less accurate. Sometimes it’s spot-on, sometimes it wildly optimistic, and other times it’s blank.
What’s the value in these speedometers if they don’t work?
Oh what’s that, MUNI / SFMTA? You don’t care, because you’ve moved on to other things?
*Two were due to very drunk drivers, who both kept on going (one ended up crashing into St. Mary’s and the other got busted near USF) and the other was due to a Trader Joe’s shopper jaywalking across Masonic north of Geary – this kind of jaywalking still happens hundreds of times a day even now.
