    Agreed. However, in addition to that, Caltrain needs to identify the more accident-prone grade crossings and build grade separations.


    Andy Chow

    There have been recently more incidents where cars made a wrong turn and got onto Caltrain tracks. I think that over-reliance on GPS is a problem. The driver may have been told by the GPS to turn right (but actually the street after the grade crossing) but turn onto the tracks since the grade crossings and the street crossings are so close and are so damn similar, given if you’re not familiar with the area.

    To cut down on these intrusions, I think the grade crossings need to have better markings not to be confused with a regular street intersections. SF’s strategy of using paint to designate zones for vehicles can be deployed. In case of Caltrain, lanes can be narrowed down and zones that cars shouldn’t be on have hash marks in place. Also, bumps have been installed at some crossings but more is needed at other crossings.

    In the longer run each grade crossing should have video cameras and senors to detect vehicle intrusion. If senor is activated the central control would be notified. Video cameras would help confirm the findings and trains can be ordered to slow down.

    Caltrain has a policy of changing out the engineer whenever a collision has occurred. If physically capable, I think some exceptions should be made to allow the same engineer with supervision to operate trains until the next passenger stop. So that passengers would be able to exit the train and seek alternative transportation. Unless the situation requires an immediate evacuation. It is not a good idea for passengers to exit the train outside the station because of steep drop from the steps onto the ground, and that the ground is unstable. It is a slow process of helping riders get off the train one by one. I have been there and has a video of me transferring from one train to another outside the station.

    I think that for any doubters, if they get on the bike and start riding, they will soon figure out that slowing down at stop signs rather than a full stop is more natural. So I fully support some type of reform of either allowing rolling stops for bikes, or allow rolling stops for bikes with special signage.

    I think the issue is whether other road users and pedestrians in particular trust that cyclists will properly exercise that additional right. A lot of the complaints that I heard about cyclists are from the elderly and disabled folks. These types of complaints allow some politicians to oppose conversations about some type of reform because of “safety” reasons.

    Those stats are for workers 16 and over. Among SF households, about 31 percent are still car-free.



    Roundabouts are practical in some locations, but in many others even mini-roundabouts could be very difficult to implement without reducing sidewalk width, which the disabled and pedestrian groups would never agree to. It would’ve been a lot better if the city had thought of roundabouts a hundred years ago, but in many of the higher-density neighbourhoods I’d say that ship has sailed. I would support any moves to install roundabouts wherever feasible.

    I want protected bike lanes on SIDE STREET…not on major car thoroughfares. Seriously, why would anyone want to bike on Masonic, Van Ness, Market, Potrero, Chaves, Alemany??? Nightmare.

    But Americans are so selfish. No one can share space. Everyone has to have their own protected space, at the expense of others. Bikes make up 3% of commuters, yet on many major thoroughfares they are now given 33%-50% of the capacity, creating hundred of thousands of tons of greenhouse gases due to stopped cars. HOW IS THIS BETTER?

    Move bike lanes to side streets. Keep us separate from cars.

    Like stated before,
    “Stop signs are pretty simple. They say ‘stop,“They don’t say ‘yield,’ they don’t say ‘slow down.’” Chief Greg Suhr.’

    If the law would of passed… I am not sure how people stop when someone suddenly appear..(They just roll stop signs)…

    Like many others, Nothing against Bike people.

    When can we get a bike friendly mayor like Sam Adams was for Portland?



    I hope you’re not an actual bus driver…



    And Uber/Lyft drivers giving rides might not be counted as riding solo.



    The lowest priority is still a priority and all this legislation could still have no results.



    I really hope Wiener tries and can whip a vote (it should be Avalos but…) from one of Yee/Tang/Farrell/Cohen so Julie Christensen has the abiity to go/no-go a veto override. And that Peskin is directly questioned as to how he’d vote on such an override.



    So, is the “among SF residents” limited to SF residents who also work within San Francisco city limits? If so, that really skews the data against Caltrain, shuttle buses, and private automobiles… and increasingly BART to Oakland, so I understand.



    The proposed Bike-Yield law and Mayor Lee’s promised veto remind one of the fear-mongering that dogged marriage equality efforts for years. The world was going to change in very bad ways, marriage was going to be degraded by extending it to non-heterosexuals, children were going to suffer, etc, etc. Then states one by one started legalizing same sex marriage, and their societies functioned much the same as before, except with greater justice, equality, and stability for everyone, including children of all married couples. Similarly, Lee and other ignorant alarmists preach how chaos and injury will follow in the wake of Bike-Yield. However, allowing bicyclists to approach intersections rationally, yielding to those with rights of way, but no longer having to fear police stings and arbitrary enforcement, will improve how people behave on the road. Our drivers and bicyclists and pedestrians will come to have similar expectations of one another’s conduct on the road and particularly at intersections. It will lead to greater understanding and civility on the part of all.



    This is such an American problem to have. In the rest of the world they’d just put up yield signs instead.


    Nicasio Nakamine

    Thanks for the clarification!



    He’s going to help them SCREW UP TRAFFIC!!! They’re going to SCREW IT UP!!! It’s a conspiracy with the all powerful BIKE LOBBY. Next thing you know we’ll have to bow down!!


    Aaron Bialick

    The numbers refer to all commutes to jobs within the city, or what the Census calls “geographic workplace,” except for figures we note are “among SF residents.” Feel free to click on the links in the article for more details.


    Nicasio Nakamine

    The survey is among SF residents. There must be more people driving in from elsewhere. As noted, the giant increase from in Uber/Lyft drivers always circulating has got to be contributing to congestion.


    Bob Gunderson

    good thing my post wasn’t an answer to your question.



    I wonder if we could get more support for bike lanes if they were also framed as “public safety lanes”. In the event of an emergency, bicyclists can easily get out of the way (unlike cars stuck in traffic), thereby leaving space for emergency vehicles. This would work especially well with paint-buffered lanes, such as those on Folsom and 8th, because they are wide enough for most vehicles. Police and fire departments should be advocating for such lanes as a way of ensuring them access through the city during periods of peak congestion.



    That wasn’t my question. My question was about touching a foot to the ground.



    This is exactly the reason, congestion doesn’t scale linearly with volume.



    That’s the problem with solo car travel, we’ve long had saturation of the streets, so the very small increase has a much greater affect.



    the survey does still show that 80% of households still own at least 1 car and 43% own 2 or more



    these numbers are just hard to believe. If there is such a small increase in driving, then why is traffic so much worse than it was 3 yrs ago. Its really undeniable.when a persons commute time increases from 28-31 minutes to about 41-44 minutes for the exact same route, its not subjective. Maybe there are just more cars now trying to get onto 101 south because most at least half of the increase in commute time is getting from inner richmond to 101. getting across the city is hard and then the terrible OCtavia design has led to long backups. same with getting off and there is very noticeable increase on oak in the AM and Fell in the PM. The ongoing construction on gough hasnt really helped either. any information on increase in commutes south vs. those from the south coming into SF. The 101 freeway backup is significantly worse as well going south in the AM and north in PM, than it is coming into SF in the AM and going south in PM. In the figure posted here, does streetsblog combine biking and walking, or is that actually combined by ACS. It seems disingenous to combine these 2 modes, as walk increase is 2nd largest increase vs. cycling in 4th. the walk increase is probably mostly driven by the immense construction in north and central SOMA, very walkable to financial district. So a lot of that is building in proximity to jobs, which of course is a good thing.
    overall this looks nice. i dont want an increase in driving either, because i am forced to commute based on where job is and where i one my home.

    also where does Uber fit into this? is it other? i guess the addition of Uber could be contributing to congestiona s well


    Karen Lynn Allen

    Well done, San Francisco! Drilling further into the data, there are some interesting tidbits. The ACS breaks out the data male/female. Women in SF drive alone to work much less than men–31% versus 37%. Women are less likely than men to walk (10.8% vs 11.6%) or bike (3% vs 5.6%) to work but are more likely to work at home (7.5% vs 6.5%) and much more likely to take public transit to work (37.9% vs 30.5%).

    Mean travel time to work is 31.7 minutes. 66% of San Franciscans’ commutes take less than 34 minutes.

    30% of San Franciscans leave their home for work between 9am and noon. Just 2% leave for work between midnight and five am.



    July 2015 federal driving numbers released today show accelerating increase in driving and a record year.

    Tree was too hazard resulting the driver hitting tree.



    Maybe it should have been removed, but that’s not the point. You said “the tree hit the big rig”, which is factually incorrect.



    “I dont think a bike yield law should let bikes proceed at full speed through intersections.”

    I don’t think a bike yield law should let bicyclists give strangers ‘wet willies’.
    I don’t think a bike yield law should let bicyclists break into people’s homes and move their furniture around.
    I don’t think a bike yield law should let bicyclists smoke cigars in movie theaters.
    I don’t think a bike yield law should let bicyclists leave the faucet running while they brush their teeth.
    I don’t think…



    With that logic, no one should ever drive because statistically no human being is capable of operating their vehicle in an absolute safe manner and is a hazard to everyone else.



    Oh and who caught this little gem from the ABC7 article above, “Emergency Response Vehicles Delayed By Dumbarton Bridge Traffic”?

    “Fire officials hope that building public awareness about the obstacle courses emergency vehicles have to navigate will make communities think twice about adding things like tree-lined medians and bike lanes.”

    Yes, because traffic would be so much better if everyone stopped biking and became solo drivers. Idiots. Note sure if the FDs actually said that or if the ABC7 writer just inferred that.



    Ugh, tacks in the road. Such a d–k move. Someone did that on Cazadero Highway in the early morning before Levi’s Gran Fondo started back in 2012. My buddy got a flat tack and won’t ride the LGF anymore, such as shame. A ride ambassador helped him change the flat very quickly and said he’d already changed a bunch of tires on the stretch due to the tacks.



    Re: the replacement of the MTC for elected officials, is there data/information on what works best? Are transit planning regional boards typically elected or appointed?

    I can see good & bad with each. Maybe a mixed board is best? Elected officials tend to kowtow to voters, which can either be democracy in action or it can be lead to watered down projects as politicos cave to demand. I am sure with more polticos we’d end up with projects like Polk St that have a bold vision and then are watered down to nothing. But then again, unaccountable/opaque boards can be dangerous too… I don’t know what structure is best, but we need strong, dedicated leaders. And lots of Federal & State funding.




    Darksoul SF

    Yea.but that tree should of been removed as it was leaning toward roadway…They should just remove all trees that maybe hazard…or they going just create more delays…possibly injuries.





    True, but the fact that cars may still be moving forward when they reach the line means that it will be more difficult to determine who got there first. It might be doable to have a regular junction with yield signs, but a roundabout would clarify for everyone who has right of way.



    I don’t know why the tree was leaning towards the road. Doesn’t change the fact that the truck hit the tree, not the other way round.


    Nicasio Nakamine

    I really got the sense at the community meeting a few months back that Captain Sanford is a good person trying to do right.

    It’s frustrating to hear Chief Suhr’s recent statement regarding the proposed Bike Yield Law (“They don’t say ‘yield,’ they don’t say ‘slow down.’”) and then see the totally normal roll-through that is unremarkable in every way except that one is Captain Sanford.


    Gary Fisher

    Hi everyone! Yes thats me on the right side of Captain Stanford, we had a pleasant meeting in the Captain’s office that day for over an Hour. We are in process. I am in Madison Wi today. I will return tomorrow. I will have another meeting with the Captain. He likes bikes! Please, he is human and a good guy.
    My work is not done.


    Jym Dyer

    At the community meeting a month back, Captain Sanford announced that he had learned that foot-down is not a requirement. Then a Sergeant from the Traffic Division, arriving late, told the same audience that foot-down is a requirement. D’oh!

    A friend of mine has an aunt who was hit in Golden Gate Park. She’s not available for interviews, though, because it was a car that hit her, and killed her.


    Jym Dyer

    @ARRO – Except that the “more pressing issues” in the eyes of the SFPD is ignoring their own Focus On The Five policies to conduct stings against bicyclists who aren’t actually threatening anybody.


    Jym Dyer

    The word on the “Speed Limit” sign means limit, not 10-20mph over.


    Jym Dyer

    Speed Limit signs say “LIMIT” yet enforcement priorities don’t adhere to that (which much worse results than we see from California Stops).


    Jym Dyer

    @jonobate – The Page Street traffic circles were half-assed implementations, with predictable half-assed results. Unfortunately they’ve been used as an exemplar for the last decade.


    Jym Dyer

    @jonobate – You prove a point with your first sentence. The law about right-of-way is simple, and it is the same for intersections with STOP signs as it is with intersections with YIELD signs and also intersections with no signs at all. Yet we have lowered our expectations for motorist competency and don’t expect them to know this. The STOP signs are there to keep them from crashing into each other so much.


    Darksoul SF

    Why was that tree leading to the road way in the first place and was it not removed to ensure safety.
