(Inspired by this post.)
The Interstate Highway System has taken a lot of the blame for urban sprawl in the U.S. Conspiracy has been blamed for destroying the urban & interurban tram systems.
So: how would you prevent it? What changes need to be made? Who needs to be removed from influence, or to gain it? Starting no further back than 1900...
Don't forget Canada, please. (Main emphasis on U.S. is fine, tho.)
TheMann said:what would have been if any one of Toronto's major mass transit plans dating back to the 1920s had come to pass.Better option: upgrade the existing Red Car system to eliminate grade crossings. (Would've been a really good idea for all the interurbans, actually.)Edward_Elric said:LA's freeway system could've been even more expansive
This contributed to the destruction of the Red Cars. Mass transit, heavily used by blacks (& the poor generally, which is still true), allowed the "undesirable" to migrate into areas wealthier (& mainly white) neighborhoods. Destroy mass transit, you keep the riff-raff out.Æsir said:A lot of the withering of public transportation in America I believe has to do with racial tensions and white flight; in Atlanta and Milwaukee from what I have heard, middle class white suburbanites fight public transport funding and infrastructure at least partly to keep minorities out of the suburbs, and the aforementioned Robert Moses was, according to the biography The Power Broker, something of a racist. Mitigating these tensions (I'm not sure they could be avoided; Blacks and "White Ethnics" wouldn't let the status quo continue forever) could mean American cities are more livable and less single-mindedly automobile focused and prevent much of the decay of inner cities in the Rust Belt and parts of the Northeast. This both involves and leads to substantial rapid transit and rail systems that either did not exist or did not survive IOTL.
You make a good point about zoning. There's also tax law at play: a lot of cities (most?) taxed farms at the urban fringe as if it was potentially developed land, rather than as farmland. That made it expensive to own & attractive to sell to developers.Edward_Elric said:The key to preserving the mass transit systems we had before WW2 is to keep pre-war zoning laws from changing too heavily in favor of auto-centric development. Have cities continue to build upwards as much as they do outwards, along with lower demand for cars (the most challenging part), and the incentive to preserve and expand the streetcar networks remains. Above all, prevent Robert Moses from controlling the urban planning of mid-century NYC. His policies rejecting mass transit investment in favor of highways largely set the tone for urban planning throughout the post-WW2 US.
Add the streetcars, which actually created the first "streetcar suburbs" in the 1910s & 1920s (earlier?). Then add the G.I. Bill, which encouraged buying new homes, as opposed to renovating older ones... Then add the mortgage income deduction, which enabled buying more expensive homes, which had the unintended effect of encouraging suburbs: higher cost wants lower taxes which wants 'burbs...
All of which contributes to sprawl. It also contributes to congestion & wasted time & more CO2...
