Uber, Lyft main reason for increased traffic congestion in SF, study finds

In other news, water remains wet.

Ride-hailing services such as Uber and Lyft accounted for approximately 50 percent of the rise in vehicle congestion in the city between 2010 and 2016, according to a report released by the San Francisco County Transportation Authority earlier today. [...]

According to the new report, ride-hail services account for 51 percent of the increase in daily vehicle hours of delay between the years of 2010 and 2016, 47 percent of the increase in vehicle miles traveled during that same time period, and 55 percent of the average speed decline on roadways during that same time period.

Ride-hailing vehicles make up an estimated 25 percent of total vehicle congestion citywide and 36 percent of delay in the downtown core, SFCTA said.

Although those cars caused increased congestion across all times of day, the increase was most pronounced during evening hours, the study found. Most congestion was spread over the densest parts of the city with up to 73 percent in the Financial District, while little impact was noted in the western and southern neighborhoods.

For those of you who have been spending years pushing Uber's party line of, "But ride-shares are environmentally friendly because they get private vehicles off the street" -- kindly fuck all the way off.

    Self-driving vehicles will make this even worse, as kids and pets run their own errands without bothering their adult chauffeurs.

    Gosh, it almost seems like there was a reason other than/in addition to creating little cartels behind the medallion system.

    But somehow pirate cabs are great if you staple on "-on the internet" and someone gets really rich.

    My gut feeling lately was that a little over a third of cars in SOMA had the Uber & Lyft stickers in the windows, so I guess hooray for occasionally being able to nail an estimate?

    I wonder if there's a way to quantify the amount of congestion these bridge and tunnel drivers cause by stopping in the middle of the lane/street, along red 'no stopping' curbs, etc. The people driving most in these areas are the ones that are the worst at it.

    It's terribly inconvenient. I've had to start looking both ways when I cross the street after I get a walk signal to be sure I'm not about to get mowed down by an Uber driver running the red light (across Market, at 10th, during morning rush hour.)

    But hey, scooters are back. So ... yay?

    Uber & Lyft blamed Amazon Prime. While I agree that's disingenuous, I also wonder what portion of the increase is due to delivery services of all types - Prime, HelloFresh, Blue Apron, Caviar, Postmates, Lugg, etc etc.

      I dont know, i ride a Scoot to/from work, basically bisecting SF east/west. And the shit-for-brains that nearly creams me swinging across 3 lanes to suddenly pull a u-turn isnt EVER a delivery driver. It is, without fail, some fucking uber/lyft driver who feels entitled to the entire god damned street.

      Think i'm exaggerating? No. These fuckers have the GALL to flip me off, after nearly killing me, every god damn time.

    So if you give people money to drive their cars around then traffic increases? Who coulda seen that coming.

  7. Paul says:

    Yes. We should all believe the SFCTA for unbiased scientific results. I am certain they have the citizen of SF best interests at heart.
    Who believes this baloney...follow the money, and the faux stats will all make sense.

      Follow the money and expect it to lead you to public transportation? Is that what you are saying? ha! ha ha! hahahahahahahahahahahahahahahahahahaha!

      Does this sort of idiotic crap sound better inside your head somehow

    Also, when most people who own cars aren't driving them, they're parked and not running. In contrast to Uber drivers, who are more likely to park and keep the car running while waiting for a rider to appear at the pick-up location or while waiting for a ride request to come in.

    And then consider all the self-important jackasses who stop in the middle of the street because they're either too lazy to pull off the road to drop off their riders, or too sheepish to tell their passengers to fuck off when asked to stop in the street.

    1 Uber driver stopping for 20 seconds and holding up traffic a dozen cars back = ~4 extra minutes engine idle time

  9. HS says:

    If Ride hailing services didn’t exist wouldnt these same people just drive their own cars or use a taxi service?

    Isn’t traffic congestation just linked to population/business increase?

      Here, let me save you the trouble of reading (or even skimming) the report:


    • Joe Luser says:

      Without uber and soon robocars, the number of cars on the street is governed by the number of places to park them at their destination. With them, the number of cars is governed by the area of road surface.

      With a sane, un-bribed government, the way to increase the number of people who can get to a destination (say for example, north beach on a friday night, or, you know, anywhere in the city anytime) is to develop managed public transit options so people can arrive without any automobile at all. As well as to develop alternatives such as bicycle lanes and safe, pleasant walkways. With a team of idiots being bribed by venture capitalists, the obvious result is obvious.
