OK, I'll bow to your expert knowledge and ask you, then: How did they make it work in Los Angeles?
And of course you must know that it's already been tried here, and failed due to financial collapse?
BTW, the national implications are that this same silly idea is being proposed wherever some two-bit politico wants to see his name in granite on a building.
Not sure as to what you are referring to, multilevel freeways or commuter rail? Commuter rail is quite successful in LA, with 7 lines. The major transit boondoggles in LA were light-rail(green line, which goes from nowhere to nowhere, stopping 3 miles short of LAX and a few miles short of connecting to the LA-Orange County and LA-Riverside rail lines) and the subway, where they insisted on wasting BILLIONS of dollars by tunnelling(the most expensive ROW you can build), and blew so much money that there was a revolt and the red line stops far short of its intended destinations.

Again, not sure what you are talking about. Commuter rail? The only one tried here in Texas so far is the Trinity Rail Express, which I earlier noted has been quite successful. Even DART's much more expensive light-rail technology(which is NOT what DCTA is proposing) has been far more successful than anticipated, the trains are packed much of the day(even in some cases outside or rush hour) from downtown to Plano. None of those lines are failing. Perhaps you mean the McKinney Ave. trolley? It is not doing very well, but it is not really transit, but originally just a tourist trolley that until this year didn't even run in the morning rush hour(it wasn't designed as a commuter transit line). Are you referring to the interurbans that used to run from Dallas to the outlying areas like Denton? Those did fail in the 30's-50's, but that was a completely different time. DFW had far less than half the population it does now, there was not much of a long commuter market from Denton Co. to Dallas, Stemmons, Uptown, Addison, Las Colinas back then(since the later four didn't exist as employment centers at the time), but there is now, and the new roads were fairly open and operating close to designed speed back then, and there were not a solid line of suburbs(feeding commuters onto roads) from Carrollton to Denton as there is now. Apples and oranges.
