Before we sink billions into 19th century infrastructure, why don't we take a look at the latest technology?

China has now introduced urban trains that don't require tracks and which cost a fraction of old style trains.

How is this much different from the parking lot trams at most major attractions? Just looks like a different form factor.

I mean, it has a steering wheel, so it's more of an articulated bus with an optical guidance system, similar to AV tech. I guess you could call it a train, since it does appear to have a fixed guidance system. I guess it depends on the definition of what is a train.

Anyway, pretty fantastic hybrid of a bus and a train. I could see something like this on Buford Highway or Cobb Parkway, with the overhead wires, looking and operating just like a light rail.

If only the Atlanta Streetcar could have been done like this. Expansion would just be a matter of buying more vehicles and installing more stations, and just simply re-paving and striping the asphalt.

It's a bus, without clear dedicated guide way. It costs far more than a conventional bus does, without the advantages that clear, hard to remove, dedicated right of way brings, and without some of the long-term operations savings that streetcars / light rail have.

I doubt this will be anywhere close to disruptive, and will likely go the way of the straddle bus.

Edit: It's pretty much just BRT, really.

I'm going to have to disagree with you on that. I think with this reaction you're being a bit closed-minded/traditionalist/set in your ways and thought patterns. Also your anti-AV-tech bias is showing.

I don't see why a fixed guideway (which defines something being a train) has to necessarily be simple-physical/mechanical and can't be computerized fixed guideway, based on sensory input and processing.

It really is just BRT. Unless it is grade separated, what will stop cars from getting in front of the Bus? It would need signal prioritization which is usually the first thing to go when car drivers get upset having to sit at lights. I think this would work perfectly on the beltline though.

This would be perfect for the Beltline and it could be up and running in a couple years rather than decades. And for a fraction of the cost.

It's an articulated bus, that still requires a wider ROW than rail-level transit. While upfront costs are lower, it would still cost as much or more over decades of use. Why are we focusing on short term solutions?

I like this technology and I see it working for a lot of cities but this will be useless with just a few inches of snow on the ground which is a big disadvantage versus steel rail that could still operate other than that its cool

That is a good point.

Luckily, doesn't seem to ever snow here anymore.
