Tale of Two Brand-New Traffic Signals – Creating Traffic Jams on Masonic Near the New Target Store

Tuesday, August 12th, 2014

Here’s your SFMTA at work.

Before, it wanted timed lights to encourage drivers to go 25 MPH:

Signal Timing Adjustments Analyzed  signal timing along Masonic and expect to be implemented  by the end of November

But now, this is what you see southbound from Anza / O’Farrell:

See that? As the light at Anza goes green, the light at Ewing Terrace goes red, so both northbound and southbound traffic backs up at Ewing Terrace whether anybody wants to cross Masonic on foot or enter or leave  Ewing Terrace in a car.

I don’t get the SFMTA,

Oh, So _That’s_ What You Mean, SFMTA? Masonic Speedrun Redux, But With Different Results This Time

Friday, January 28th, 2011

Get up to speed here.

Oh, OK, I see what you’re talking about now. (Sort of odd about how taxi drivers were complaining about something they experienced that hadn’t actually occurred yet, but anyway…)

Traffic heading south from Mervyn’s Heights now has timed lights, sort of, on Masonic Avenue.

Those wishing to exceed the posted 25 MPH speed limit will need to start running red lights.

We’ll have to wait and see how this all turns out…

Masonic Avenue Speedrun: From Anza to the Panhandle in About 75 Seconds – SFMTA Says This is Impossible

Tuesday, January 11th, 2011

What’s our horrible SFMTA, the people who bring you (sort of, sometimes) MUNI, crowing about these days? It’s the recent rejiggering of the traffic signals on Masonic to change driver behavior. Check it:

“With the change in timing, motorists travelling south from Geary to Fell will find generally that when they exceed the 25 speed limit, they’ll get more red lights.”

Mmmm. I guess how many red lights you get depends on whether you start traveling “south from Geary” from southbound Masonic or eastbound or westbound Geary. So let’s test SFMTA’s claims from the next intersection, the one at Anza and Masonic in Mervyn’s Heights.

Let’s see how many red lights you get as punishment for exceeding 25 MPH, shall we? The answer is zero, none, no red lights, ningunas luces rojas, mi amiga. You’ll get a green at Turk, Golden Gate, Fulton, Grove, Hayes and then Fell. See?


So that’s strike one. (I’ll tell you, taxi drivers and Sunset District denizens and late-night MUNI bus drivers would just looooove to transition betwixt the Bush/Pine corridor and the Fell/Oak corridor by using the Masonic corridor at an even 25 MPH.)

(I’m thinking if cab drivers would have anything to complain about, it would be hitting a red light at Anza after coming down Masonic through the green at Geary. The light at Anza used to favor southbound traffic coming from the Trader Joe’s area and now it does not. But that has nothing to do with whether you drive at 15 or 25 or 35 – these days, you’ll hit a red at Anza irregardless.)

Here’s strike two:

“Only the southbound signals have been adjusted since two-way traffic, as on Masonic, poses too many traffic engineering problems to make bi-directional adjustments.”

Now, how on Gaia’s Tierra Verde can you adjust the southbound signals without adjusting the northbound signals? Helloooo, McFly!

All the way to the bottom, Maggie. You made it!

And let’s see here, how can we get a strike-out? Oh, the SFMTA conducted a poll of people who showed up to the let’s-plant-more-trees-on-Masonic meeting and then asked them, hey, do you think we should plant trees on Masonic with Other People’s Money, with money that fell from the sky? Well, guess what? Most of the people who showed at the let’s-plant-more-trees-on-Masonic meeting at the Rich White Kids private school supported the idea of  planting of more trees on Masonic. Surprise, surprise.

That’s strike three.

Now of course the SFMTA has the power to make changes to take out parking spaces to improve the safety situation on Masonic right now, but the people in charge over there feel that that would lower the chances of getting approval to spend eight figures of OPM and years and years to plant trees on Masonic and move existing trees or cut them down or narrow the sidewalks or take out some parking spaces to improve safety

For some reason the SFMTA has a strong focus on aesthetics.

Why Do the Traffic Signals on Geary All Turn Green at the Same Time? Doesn’t That Encourage Speeding?

In the sense that the faster you go, the more intersections you can get through.

See this trail of green lights stretching out to infinity? That’s how they roll in the Richmond District:

The Great Slowdown of Fell and Oak Streets – Synchronized Signals Retimed for 25 MPH

Tuesday, April 6th, 2010

I’ll tell you, there are three things limiting the speed of drivers on the one-way, multilane twin streets of Fell and Oak.

1. Speed limits (oh maybe not, let’s scratch that one out);

2. Traffic congestion (particularly during this era of that albatross hanging from the metaphorical neck of The Boulevard Movement and The “Livable” Streets Movement, monstrous, needlessly wide Octavia Boulevard); und

3. The timing of the synchronized traffic signals.

Well, it appears as if #3 is going to change -  per Bike NOPA Fell and Oak will soon have their signals synchronized for 25 MPH.

There’s not a whole bunch of documentation on this action, documentation that I can find anyway. (You can play too, just try to find something at the SFMTA or SFGov.org websites.) But I seen them workers messing with the signals boxes lately, so allow me to jump to the conclusion that something is afoot.

Soon, you’ll have a chance to read the signs these hectoring hula hoopers regularly hold at Fell and Masonic:

Will this affect drivers all that much? We’ll see.

Certainly, there will be a period of adjustment as there was when lights were re-timed on the similar matched set of Turk and Golden Gate.

Will some drivers jump on the gas and then the brake at every light, aggressive taxi driver style? Oh yes.

Will the residents of the west side be happy? Oh no, not if they notice.

Anyway, brace yourselves. This should be a done deal by the end of the month.
