Making "protected" bike lanes safe
For six or seven years, the loudest and best financed bike lobbying organizations
have been saying we need "protected" bike lanes everywhere. They say it's obviously inadequate to have just a paint stripe separating bikes from cars; we need at _least_ posts, and preferably a line of parked cars. You know, so the bicyclists are totally hidden from motorists until the motorist crosses the bike lane to access a street or driveway. Segregation skeptics have been saying for just as long that the "protection" vanishes precisely where the conflicts are worse. And the design adds new surprises to traffic interactions. Surprises in traffic are NOT good. And there have been crashes, just as predicted. A mile of "protected" bike lane put in Columbus, Ohio a few years ago went from 1.5 car-bike crashes per year to 13 crashes (IIRC) in the year it was installed. And here's the latest one: https://sf.streetsblog.org/2019/04/0...e-mixing-zone/ The solution? "Protected" intersections everywhere! https://vimeo.com/86721046 I haven't seen any cost estimates for this new cycling nirvana. That would be interesting. - Frank Krygowski |

Making "protected" bike lanes safe
It's all folly until we ban cars from areas where there are cyclists and peds present.

The other big issue that cities face is cars, and other vehicles using unprotected bike lanes for various other purposes. Passing on the right. Drifting into the bike lane. Deliveries. Pick-up and drop-off. Pulling over a driver to give them a traffic ticket. Turn on your emergency flashers and the whole world's a parking space. Stick a cone behind a delivery or service vehicle and you're good to park there for a long time. If we want to increase the percentages of cyclists we have to increase both actual safety and the perception of safety. Just putting protected bike lanes in areas where there are the most conflicts is probably sufficient. The other issue is at intersections you need to bring the bicycles and pedestrians closer together to avoid right hooks (or left hooks in left-drive countries). There are other issues to consider as well, how do you do street cleaning? How do you pick up garbage in areas where the trash cans need to be by the curb? |

Segregated facilities can be a nightmare with high traffic volumes -- apart from the cleaning issues. What I never understood about the SCV was why people weren't riding back when I commuted everywhere in the '70s and early '80s. I didn't even own a car for most of that time. Sunny weather, wide streets, moderate traffic volumes -- probably way better than now, and nobody rode to work. I assume ridership has increased and that the cities can justify the expense of special facilities. -- Jay Beattie. |

Of course there are problems with roads everywhere. Along the beach in Alameda they tried putting the bike lane two way along the beach side. This puts the parking lane outside. So people park and throw their doors open into traffic. And passengers throw their doors open into the bike lane. And the two way traffic on the bike lane puts Joe Pretend Racer one the same path that a 3 year old on a balance bike is riding. Can you see any practical way of improving it? |

Not really -- except with education and vigorous enforcement of traffic laws requiring motorists to treat the bike lanes like traffic lanes. Even with my magic flasher, some absolute dolt right hooked me into an athletic field on the way home last night -- at the Under Armor headquarters. http://tinyurl.com/y73ckzzy This is the very noticeable bike facility out front. http://tinyurl.com/yy7haffg The place is choked with witless runners looking for parking spots. Meanwhile, riding in the super-duper bicycle facility this morning, my son put it well: "I'm going to have an aneurysm." It's a nightmare of on-street and separated two-way bike and pedestrian facilities -- kooks on bikes, buses, trains, etc., etc. Looks good on paper but sucks in reality. https://bikeportland.org/2015/08/14/...et-bike-155284 This intersection is a little death trap: https://s3-us-west-2.amazonaws.com/s...y-bend-559.png And while I'm complaining, who thought up the f****** dimpled plastic curb cut transitions: https://adatile.com/wp-content/uploa...l-1030x773.jpg They're everywhere and slippery as sh** in the rain, which means they're slippery much of the year. If you hit one even slightly leaned into a turn, you're slipping, and if you have poor reflexes, you're going down. I'm amazed I haven't seen more crashes on those things. The real solution is moving to some place with adequately wide roads and fewer cars -- yet progressive enough that the guys-with-banjos aren't trying to kill you. I'm not sure where that is. Maybe Frank's magical village. -- Jay Beattie. |

Building some separated bike lanes isn't cheap nor is it outrageously expensive, and sometimes major corporations will chip in, see https://9to5mac.com/2019/04/03/apple-cupertino-transportation-funding/. Hey, I got quoted! I don't really agree with my vice-mayor on this, I feel that Apple can decide which projects, if any, that they want to fund and that it's better to work with Apple than to be in adversarial relationship. If there's a region wide business tax to fund transportation, housing, etc., then that would be a better solution than each city going it alone. However in Mountain View, in 2018, voters passed a business tax that will disproportionately affect Google, but Google didn't oppose it since the reality is that the amount they will pay is lost in the noise. |

But has all this money spent and work done significantly increased the number of bicyclists? The U.S. population grew 0.7% in 2017, does the growth in the use of bicycles grow at the same rate? The U.S. Census Bureau says not, that Nationally, the percentage of people who say they use a bike to get to work fell by 3.2 percent from 2016 to 2017. https://www.usatoday.com/story/news/...ms/2319972002/ -- cheers, John B. |

I find it strange that you would say such a thing as I ride in Bangkok with such chaotic traffic that most foreigners visiting the country are quite literally afraid to drive here and we have no such thing as a protected bike lane. And yet in the 20 or so years that I've ridden a bicycle here I have yet to have what one might call a "close call". Perhaps because I am careful to obey traffic regulations and watch what is happening around me.
