“Together we’re advancing initiatives focused on creating safer, more efficient travel options for all modes of transportation, from vehicles to bicycles to pedestrians,” Dave Ambuehl, the chief deputy district director of Caltrans, said in a news release.

I support a car ban, but these are actually very well designed.
Theyre extremely car-centric, space-inefficient, wildly expensive, and don’t do anything to solve traffic.
None of which are problems they’re actually trying to tackle.
They improve traffic a bit (not solve), and are substantially safer. They’re only meant to do those 2 things, and they’re good at it. Nobody thinks a single intersection idea will fix transportation as we know it.

They spent $25M not making travel safer for bicycles and pedestrians, and explicitly making travel less efficient by inducing car demand. $25M could buy Caltrans an entire set of one of their new Stadler kiss trains, to go from 24 trains sets to 25.
edit: Actually this intersection is more dangerous than the existing intersection. It doubles the amount of pedestrian signals that pedestrians have to cross, and eliminates the sidewalk on the east side. Plus, they’re cutting down like 8 trees and not replacing them. This is urban decay.
I explicitly said I’m anti-car (read: I’m aware they’re car-centric). The rest of this is either outright false, or isn’t solved more effectively by any car-centric alternative.
Diverging diamonds are among the best interchanges in existence. That doesn’t mean they’re great, but they solve far more problems than they introduce.
Please direct your weapons where they actually matter–asphalt itself.
It just seems strange to portray highway interchanges in a positive light. Like, they might be the safest interchange for stroads intersecting an interstate, but that’s kinda like putting a $25M bandaid on a bullet wound.
they solve far more problems than they introduce.
It is worse for pedestrians, who now have twice as many traffic signals to wait for. It is worse for cyclists, with “gauntlet” bike lanes running between through- and right-turning lane. It is only better for cars…so hardly the “best” interchange in existence.
I have no clue how you are getting down voted in a fuckcars community for pointing out this infrastructure is still car centric and does nothing to solve traffic, only induce demand.
If this area was designed for people only it would not look like this.
This is still city planners creating a dangerous strode and intersecting it with a interstate highway and calling it good enough.
These are legitimately some of the only interchange designs which integrate nicely with pedestrian paths and bike lanes.
I’m not sure if there’s any safe way to have level crossings for bicycles and pedestrians across highway ramps. The safe ones are almost always underpasses or overpasses. There’s a bicycle path in Stockholm at the end of a highway ramp as it merges onto a 50 km/h road, and I’m terrified to use it.
North American has this concept in roadway design where traffic engineers feel the need to make every roadway large. Think of interstate interchanges.
There is also this need to try and design roadways as both roads and streets, while maintaining the flow of high speed traffic at the same. This leaves us with neither good roads or enjoyable streets.
Roads get you from point A to point B without regard for what’s in between or along the route. They are meant to move large amounts of traffic with minimal to no lights/stops/driveways.
Streets on the other hand are “destinations” and are meant for the people that live along them. Streets are traffic calmed, streets give the right of way to pedestrians. Streets have driveways, and multiple interaction zones between people on foot, on bikes, and on cars.
A street cannot act as a road nor can a road act as a street.
This image trys to turn the underpass into a street (which it can be), but it’s main function is still designed as a high-speed roadway. So this leaves us with a combination of the two (a strode) which neight is a good road or a enjoyable street for the local community.
Some examples of simplified highway off ramps that connect directly into traffic calmed streets.
City planing also plays a role here, and its usually has to do how our we build city centres right next to highway off ramps. This leaves no room for proper roadway design where you “stepdown” your roadway classification.
Good planing would have a interstate (130-100kph) connect to a highway (100-80kph), which then empties into a high-speed road (80-60kph), which steps down to a road 50-40kph, and then transitions into a street (30-10kph).
Instead we have interstate highways empty right into a city street.
I’m not saying it’s good (those bike lanes look horrible), but they put in a diamond interchange in my city and it’s ironically the best car infrastructure we have.
To be fair this looks slightly worse than ours, ours has more separation for pedestrians, but I feel much less stressed out that I only have to look one way when crossing, and no cars should be able to go when I am.
They still do. they’ll run a green arrow light, probably because they’re used to “right turn on red”. I have been tapped by a car I was playing chicken with at that light.
But other than the presence of morons, I’d pick the FREEWAY INTERCHANGE over a normal city light any day. That’s crazy to say but it just goes to show how even slightly better designed infrastructure makes a difference.
Those bicycle lanes are ass though.
Fuck cars
But if there are cars, you want these
Yeah diamond interchanges kick ass. They made me nervous the first time I used one, since it was the kind where you end up driving on the opposite side of the road. But just follow signs and you’ll get where you need to go and there’s almost no risk compared to the garbage interchanges you usually see around interstates.
I wouldnt bike on that painted bike lane across a right turn slip lane designed to make cars slow down as little as possible coming off the freeway
There should be a protected bike lane in the median with a dedicated signal where the diamonds cross
Those aren’t bike lanes. They are merging guides for the cars. So yeah it’s still lacking but better than a cloverleaf.
Edit: sorry, there are bike lanes. I hadn’t noticed that there were two colors on my mobile
Since there are traffic lights, I personally would no be worried about taking my bike through
