I’ve Never Seen a New-School LED Traffic Signal Not Working, But Here’s One – On Hayes Street – But It Got Fixed, Quickly, Via 311

Thursday, February 11th, 2016

[Oh look, it’s me being “upbeat.” WARNING: Boredom ahead – feel free to click off somewhere else.]

I’ll tell you back in the day, traffic signals used to get busted all the time, cause incandescent bulbs would burn out. Then we got LED lights instead – a bunch of little points of light, so if one two go bad it’s no biggee because there are tons of others telling you to stop.

Of course it’s possible for the entire assembly to lose its power for other reasons, as here, on Hayes:

I’ve never seen this before. (This is the point of my post, sorry.) So I called 311 and (unlike the cases where low-level RPD workers beg me, literally beg me, to call 311 to get whatever issue right on up to the Big Guy in McLaren Lodge the next morning) I got through with a quickness and then I never noticed this busted signal again, like the next day.

IDK why 311 thinks I need some case # – it’s like my duty is extinguished as soon as I hang up. It’s on you guys now.

(I’ll tell you, one time I called the 911 for a missing manhole (personhole? I lack the proper vocabulary, obvs. In my day we called ’em “manhole covers” ’cause THAT WAS THE WAY WE LIKED IT) cover on Fell at Lyon in the Western Addition. And 911 was like, oh, we’ll contact DPW (with the implication being that that’s what I should have done instead) and I’m like, thinking to myself here, uh, no, if somebody on a moped on Fell runs over this giant hole, IT’S GOOD-NIGHT NURSE. Ergo, that’s the emergency.)

Anyway, the System works, sometimes…

Here It Is: The Effect of Our New LED Street Lamps in Golden Gate Park

Tuesday, December 15th, 2015

On the right you can see the new LEDs and on the left you can see the pinkish brownish light you get from regular old street lamps.

That’s it. That was the cause for all the hullaballoo.

And any org what crows about all the benefits of this change is the very same org that burns some street lamps all the livelong day, 24/7/365 for something like a year now.

Oh well…

This Street Light Has Been Burning Brightly All Year Long: Daytime, Nighttime, All the Time – Our City Family Just Don’t Care

As seen on Fell:

It mocks me.

One assumes its failure mode is to be on all the time, so that somebody will notice. One assumes that there’s a photosensitive switch up there what got occluded by something.

One assumes…

LED Lighting for the Golden Gate Park for “Safety,” But Not Really – Installers Witness Lamps Blazing Away 24-7

Wednesday, August 26th, 2015

SFGov has learned to justify anything and everything as a matter of “safety.”

As here, where LED lights are going in:

7J7C2123 copy

Now IRL, what these LEDs will do is save money, prolly, over time. The connection to safety is tenuous, certainly.

Hey, what’s that in the background? Is it Yet Another Streetlight in the area what’s been on 24-7 for half a year? Yep.

Does SFGov care? Nope.

Are there many other examples of this in the area? Yep.

Oh well.

Corporate Joke: “ENBRIGHTEN” from GE – Making a Verb a Verb Again

Tuesday, July 21st, 2015

[UPDATE: And, oh yes, A Noble Spirit Embiggens The Smallest Man – see Comments.]

Here you go, know your en- and your -en

Prefix: en- “…forming verbs”

Suffix: -en “makes the word a verb”

Put them together and you’ve got enbrighten:

The only similar I can think of is enliven, which, of course, is a synonym of liven.

(Srs. suggestion: Why not Enbright instead? )

All right, GE, keep on enbrightening our world…

An “Urbanist’s” Dream: Here’s Your Chance to Help Plan the Future of the Clipper Card – It’s “FutureOfClipper.Org”

Tuesday, December 2nd, 2014

I had a Clipper Card once. Well, a TransLink, the Clipper’s predecessor. Turns out it couldn’t handle a little acetone:

And now I have no Clipper Cards, AFAIK

But you, you love the (somewhat racist?) Clipper. So why not help the MTC try to make it better?

All the deets:

“Help Plan the Future of Clipper – MTC and Bay Area Transit Agencies Invite Public Input

OAKLAND, Calif., Dec. 1, 2014 /PRNewswire/ — Where would you like to use Clipper, and how would you like to use it? That’s what the Metropolitan Transportation Commission (MTC) and Bay Area transit agencies want to know.

Clipper is the transit fare payment system for the San Francisco Bay Area and is currently accepted for payment on 13 transit agencies. The reloadable card was launched in 2006. Today, the system has more than 1.4 million cards in circulation and is used for more than 700,000 daily trips.

Whether you use Clipper right now or not, you can provide valuable feedback that will help MTC and its partner agencies design the fare payment system that best serves Bay Area transit riders.

Visit futureofclipper.com and click the link to take a survey to provide your feedback. You can also share your experiences with Clipper and what you’d like to see in the future via email at feedback@futureofclipper.com or via voicemail at 510.817.5680.

Burning Daylight: Why are the Streetlights of Presidio Heights ON in the Daytime?

Tuesday, July 29th, 2014

Let’s see here, Presidio Heights has had fancier-than-average street lights for a while now, ’cause why not, right?

These days, LED lights are the new thang, so Presidio Heights is getting them as well. And SFGov puts up signs for the rich denizens asking, “Hey what do you think of the new lights, let us know,” kind of thing.

But these new lights are on like all the time. Like this:

Oh well.

Our streetlight people must think we’re made of money.

AND THAT REALLY GRINDS MY GEARS!*

Pick a stupid catch-phrase for the SFPUC to use about LED lights, which I’ve had in my crib for years:

1. leading edge

2. state of the art

3. world-class

The answers are #1 and #2 – I haven’t come across the SFPUC talking about the “world-class” lights they leave on all the live long day yet, but one of these days I prolly will.

Don’t stop believin’
Hold on to that feelin’
Streetlight people

*Not really. But I’m pointing out just one example of a pretty big difference betwixt how our PUC sees itself and how it actually is IRL.

Reader Notes:

The San Francisco Public Utilities Commission invites interested community members to attend a public meeting to discuss our upcoming Street Light Wireless Control Pilot Project.

The purpose of this pilot project is to test a suite of leading edge wireless technologies which will be mounted on several new, environmentally friendly LED street light fixtures in the vicinity of Washington Street between Arguello and Presidio. Some of the wireless technologies will enable more effective monitoring and control of LED fixtures (including adaptive lighting, which allows for off-peak hour modification of street light levels), and some technologies will support other services, like electric meter reading, pollution monitoring and traffic signal control. The pilot project will allow us to try out the proposed technologies before the City begins converting all City-owned street lamps to LED fixtures.

MEETING DATE AND LOCATION:
January 16, 2013
6:30pm to 7:30pm
Presidio Branch, SF Public Library
3150 Sacramento Street, at Lyon
Downstairs Meeting Room
For more information, contact:  Kenya Briggs, San Francisco Public Utilities Commission, Communications Division,415-554-0715kbriggs@sfwater.org.
(Please note: this is not a Library Sponsored Program.)

And there’s this:

We’re testing a state-of-the-art street lighting system comprising light-emitting diode (LED) street lights and wireless monitoring and control equipment. The new remote controls and ultra-efficient LED fixtures, which replace high-pressure sodium street light fixtures, have been installed in these neighborhoods:
The Inner Sunset, on Irving Street between 7th Avenue and 14th Avenue
Presidio Heights, on Washington Street between Walnut Street and Maple Street
Our public survey period ended at close of business on February 24, 2014. Many, many thanks to everyone who participated in the online survey and live demonstration events. You can read a comprehensive analysis of the survey results here.

Residents and businesses in the test areas were briefed on the installations during community meetings last winter. The new, ultra-efficient LED street lights will consume 50% less energy and burn three-to-four times longer than existing lamps. In addition, the LED’s will be:

monitored and controlled remotely (removing the need for members of the public to report broken lamps)

equipped with an adaptive lighting feature which allows for energy-saving off-peak hour adjustment of street light levels

powered by 100% greenhouse gas-free Hetch Hetchy hydroelectric energy (just like all City street lights)

Thanks for your support! Please feel free to contact us with questions or suggestions at: LED@sfwater.org.

(NOTE: A third LED street light system with wireless controls, installed downtown on Pine Street between Davis and Montgomery, was not included in the online survey or live demonstration events. Live, on-site demonstrations of the Irving and Washington Street installations took place on January 22 and 23, 2014.)”

At first I was thinking…Easter?

And then I thought Boston Marathon.

And then I realized it was for the GSW.

Is it a little cheesy to do this so far ahead of time?

Yep, IMO.

Oakland doesn’t have much, you know.

They were going to get a pair of pandas from China, but that didn’t work out.

Oh well.

That’s Venus, the Evening Star, to the right of the dome, BTW.

How do these lights know when to flash on?

This kind of thing is similar to but different from revolights, right?
