I’m pretty sure it’s just going to be a cookie cutter intersection, with the 4 fans from the original roundabout turned into 4 malls.
Let’s wait to see the actual design.
They said they will move the now submerged bus lanes up to surface level.
By eliminating the roundabout, will they also add left turning lanes?
If they were really serious about making this city better, they would rip down the hulking monstrous multilane overpass higways above. I am confident however that they won’t do anything like that. Only the early Ko administration thought of doing things like taking down those ugly hulking overpass highways—and does anyone think this made the Beimen zone worse?

The city would look better, but traffic would be terrible… Before they built Civil boulevard, driving from west Taipei to East Taipei was slow… I don’t remember how Xindian to Taipei was before but guess it was way worse before they built that overpass
Extend cycle time at the traffic light: reduced long term throughput. Add more lanes: reduced long term throughput.
Then, wider roads are more dangerous for pedestrians to cross, and would take longer for them to cross, so you need longer pedestrian signals, and we get even lower throughput.
In this video, some of those peanut roundabouts aren’t double roundabouts. It’s just a way to squeeze a roundabout interchange into just building 1 bridge across the parkway.
That is happening in Taipei these days too, quite frequently in my experience. Taipei City that is, New Taipei, nah, old habits don’t die that easily there.

Different names…. Europe is filled with Roundabouts, any place that has enough space then it is a roundabout instead of a crossing…
Must be a tourist attraction 
There are so many unnecessary traffic signals I really hope they don’t give up on roundabouts/traffic circles. Maybe they need to continue to try to adjust them to taiwan style driving instead of trying to change the driving habits.
That’s why the uk generally puts the major through road on the bridge, then you can have the extended roundabout underneath.
Thats the one on the road sign above, that diagram makes it look a lot more complicated than it is, its acutely quite easy to use, well it was before sat nave as you have to have an idea of where your going before you enter it, and if your confused just stick to the second lane and use as a big roundabout with intersections till you get to your exit, no need to enter the middle bit.
The first thing they need to do is stop trying to fit the additional scooter lane on the outside, making it so you need traffic lights.
Yeah, it’s a bit annoying when it’s a scooter. I don’t need that level of care.
Plenty of public transport already available, plus they can use the space to build bus lanes, bike lanes, etc. Taipei should follow many cities around the world implementing active policies to discourage private motor vehicles within the city center, which in Taipei should be pretty much the whole city.
Frankly I am seeing the opposite happening, with pedestrian spaces shrunk—carved outs for scooter parking along Roosevelt Road NOT taken from the road but from the sidewalks, effectively shinking them; pedestrians crossings narrowed to ridiculously small amounts of space, and so on. I am not impressed at all by this new mayor.

It’s hard, as the Taiwanese loves their cars 
Hard for the politicians to do this. They have tried with MRT and scooter/car parking at the outer stations, but most people with cars still drive all the way.
Remember FuXing North road, when they removed one car lane and made it a bicycle lane? It was awesome in my view, but the city Mayor got lots of heat on this… Not certain any politicians would dare to do this again on such an important road….
They also did this sidewalk widening on Xinsheng South Road. It’s not perfect but what an improvement in the overall vibe!
Chiang Wan-an appears intent on pulling us in the opposite direction, with no positive initiatives like this in sight . . .

What else was built during that time?

Thank you!
Turbo roundabout:
Basically it’s designed to give higher throughput to the directions with more cars. So when traffic loads of incoming roads aren’t balanced, the direction requiring higher throughput won’t have to wait for cars coming from the direction with lower throughput.
