The sheer number of people that simply (out of ignorance or malice) will use these as a turn lane… parking space… what have you probably has a bit to do with it.
Tangentially related: theres a lot of distracted and shitty drivers out there. Putting something physical between you and them tends ro make people feel safer.
I’m pretty sure this study probably could have been replaced by common sense. That said - if the presence of a study results in better handling of bike lanes… good on it.
Most studies are to quantify common sense 😀
People that park in bike lanes should lose their license and car. Selfish and hazardous behavior.
when you ride your bike and encounter a obstacle like this, be safe!
- slow down
- watch for traffic
- pass the obstacle on either side
- spit on a window in passing
- get back into the bike line and continue.
4 is best replaced by taking out the u lock from your belt and hitting the side mirror or window with it as you pass
I genuinely think they need more than a painted bike and a single white line every quarter mile… and the occasional solitary sign every couple miles. Different colored paint or better signalling would go a long way in solving actual mistakes and would also kill off “willful ignorance.” If its obvious and clearly marked you can be more aggressive with tows and tickets which, in a perfect world, could finance more of the same. Open lanes could work in places where its not as easy or convenient to ‘be that guy .’
Studies are used to increase funding and change infrastructure. This is good.
Not surprising, looking at the photo of the painted bike lane in the study. That’s just a death trap.
I mean, even in countries with a huge number of protected lanes such as the Netherlands there are (fully) painted bike lanes as well, but not with cars rushing by on both sides at high speeds.
I’m Dutch and those ““painted”” and “sharrow”" wouldn’t even count as bicycle lanes. You’re surrounded by cars on both sides, there’s no clear markings it’s for bicycles, nothing nada.
If I were an urban designer/mayor I’d fire whoever thought it’d be a good idea to build it that way.
In my view, these would be requirements:
Painted:
- Only bicyclists allowed.
- Only if the car lanes are ≤30 km/hr
- Two car lanes max on the road.
- Not at corners with bad visibility (there it should be protected)
- Lane must clearly be marked with a 🚲 symbol
- Lane must be painted differently than the car lane
- On at least one side of the lane, a mainwalk should be present. No car lane there.
- Preferably, if there is a car lane on one side, it should be for public transit only.
Protected:
- All of the above.
- Both sides of the bikelane must be separate from the car lane, if any. Both sides must provide either a hedge, raised plant area, raised ‘border’, raised fence, and/or mainwalk. If only a raised ‘border’, then cars must not drive faster than 30 km/h.
- Bike area can be elevated as well.
Problem with the plants is that eventually they become a hazard for bicycles. Best not to put something there that requires weekely maintenance
You can have slow-growing hedges at a slight distance (~0.5 m to 1 m) from the path, or the plants could be in boxes.
Something like this is also possible:

The hedges typically don’t really require weekly maintenance - once every few months suffices.
Alternatively, trees could be used, with grass and flowers inbetween.
Do that in a city that doesn’t care about bicycles, and the plants will be trimmed literally never.
I’ve seen it too often. You get one person to install a bike lane. It’s a major win. But the city doesn’t consider it real infrastructure, so they just ignore it and never maintain it.
All of the above
I don’t think you mean this do you? Or do you really think there shouldn’t be any kind of bike path when the speed limit is greater than 30 km/h, or the road has more than 2 lanes?
What @EggInDisguise@lemmy.blahaj.zone said, goes. But as for the amount of lanes, I do think I overlooked that one, so I edited my comment just now. I do think it’s worth in general to reduce the amount of car lanes (given that induced demand’s a thing).
Still, for protected bike lanes that are fully separate from car lanes, by a strong barrier (not just an elevation), I think you could do with 4, maybe 6 lanes. More would be dangerous for all, though.
We also have ‘bicycle main pathes’ where car drivers are ‘guests’. That is, cars must drive behind bicyclists and not overtake them. They generally are in 30 km/hr zones, and the width of 2 car lanes (so about 7 m). Sidewalks are also present there, of course.
Not sure if they edited their comment, but after “all of the above” they specify the 30kph as “if it’s only a raised border” and not a full size wall/barrier.
Side note: Honestly, slapping a 2-3in stepped concrete block and keeping the cycling lane raised to match that step would go a long way in keeping people off it. People don’t like driving on cracks, they’ll avoid a large contrasting colored step like the plague
Unsurprising that actually feeling safe increases use over “trust everyone bro, even the people who threaten you, painted lines will stop them!”
Paint is not infrastructure, no surprises there.
If they widened the roads to be able have space to make the lane id say it is. If they just threw it in there and made a uncomfortable spot to bike id say not.
And millions of drivers would disagree. The study is clear. If a driver doesn’t fear hitting something they mostly disregard painted lanes. Without protection bikers fear the lane with good reason.
I didnt say they wouldn’t. But its still infrastructure if they widened the roads for it.
But since automobiles use it and bicyclist don’t, the point is that makes it more car infrastructure not bicycle infrastructure
And important that the bike lane doesn’t go over sewer grates 🤦
That sir is not a bike lane hahaha.
Cyclists trust New Yorkers to drive like New Yorkers, yes.
