Why rip up beautiful Geneva, when Zurich already has a car-free city center along Bahnhofstrasse? They could simply replace the tram rails with walkways.
Then again... why did they destroy the convenient walkways at Newark airport? Now, I have to walk miles in pain or hope a transport will deign to pick me up and bring me to the gate.

The elephant in the room is not the initial construction costs (although they would be staggering--all paid for by money extorted from taxpayers), but maintenance costs. <p> The existing airport walkways are short indoor sections in clean, climate-controlled airports, with light traffic. Even so, they are often closed for repairs. Escalators in subway stations are a better approximation: while they are indoors and very short, they are subject to heavy traffic and mud tracked-in by pedestrians. In my experience, these escalators require maintenance with troubling frequency--one run at least is out-of-order, whenever I use them. <p> What they propose here is a miles-long, complex system, with additional accelerating transfer belts, all outdoors, exposed to elements, trash, and mud, and with heavy traffic. These walkways will require *nearly constant, expensive maintenance*. And since they will be maintained by civic bureaucracies, the process is bound to be inefficient: there will be special city agencies to do the task, with five paper-pushers per one actual maintenance worker. <p> All the staggering costs of this barely-functional system will be paid by you, the taxpayer. This will kill two birds with one stone: you will have to use the walkways, because you will no longer be able to /afford/ a car. <p> A much better system, in my opinion, is to triple or quadruple the size of the existing bus fleet (and thus the frequency and/or coverage of buses), close the entire midtown to car traffic, and change the ticket scheme so that you would buy an all-day ticket, and could use and switch buses freely throughout the day. This will cost /much less/ than the walkways, *use existing road infrastructure*, use existing (OK, somewhat enlarged) maintenance facilities for buses, and actually reduce road maintenance costs. And a bus that breaks down will not bring all traffic on a route to a halt, the way a broken walkway would.
The buses would cause much less pollution than the equivalent cars to begin with; and the fleet could be smoothly transitioned to all-electric buses gradually, at whatever rate the city could afford.

Indeed, the car-free center that Zurich set up some 40 years ago really works well.
As for belt system; read all about it in: "The Caves of Steel", by Isaac Asimov.

How about .........................just walk!

How about changing the zoning laws so that we can live and work on the same block, and not need transportation every day.

Americans are already too fat, now that they will not have to walk just expect waistlines to increase.

Isaac Asimov and Sir Arthur C. Clarke and others would be pleased to see this study implemented. The Whiners can pound salt. Similar Whines have been made about things like the Interstate Highway System but none-the-less society has benefited greatly by these systems. Asimov & Clarke would also be interested in seeing the various Hyperloop transport systems be come to fruition. Governor Clinton, of New York, was widely ridiculed for building the Erie Canal that joined the westernmost navigable portion of the Hudson river to the Great Lakes. The bonds that were issued were structured to mature over 50 years and many Americans lamented that traffic on the canal would never justify it's cost. In fact, the "50 year" traffic volume was achieved in the FIRST year and inside of the canal's first decade it had to be progressively and rapidly rebuilt to keep up with the huge volume of traffic. The Erie canal literally is the tool that opened the interior of the U.S. by joining the east coast to the great lakes and the Mississippi river system to the Gulf of Mexico. Try thinking on a somewhat larger and more optimistic scale. And, also budget for the needed maintenance costs.

Read Heinlein’s story years ago, loved the idea. Bellagio and Caesar’s in Las Vegas, and LV airport, have (or had) fairly long moving walkways. Wish there were an easy solution which would include the many people, old and young, who (at least here in California) can’t walk; or can’t walk quickly; can’t walk far; can’t be on their feet too long; aren’t sturdy on their feet; have to use a cane, crutches, walker or wheelchair; have a service animal; or are pushing strollers and baby carriage(s).

Walkways are a ridiculous idea and should be left to fiction. The cost and maintenance make this a non-starter. Add to that most people don't want to walk or can't walk. Think of the millions of old, frail, overweight, injured, kids, etc people and then add the lazy ones. Yep, that's about 80% of people. And how do one carry your shopping on these walkways if you have to go 3 miles? You go do my grocery shopping and bring it home if you like these walkways so much. And I'm fit, strong, healthy and love exercise. And how about using these in the rain, snow and when it's below freezing? Impractical.
The answer to city transportation is arriving fast. Autonomous electric vehicles. Clean, efficient, safe, silent, cost-effective and the answer to all our current problems. If anything, pedestrians just muck up traffic. Most traffic issues are caused by cars having to stop at intersections for pedestrians to cross. With no pedestrians crossing at intersections autonomous vehicles can solve virtually all our other congestion issues.
