the future of urban transportation

I like the vision of future urban transportation laid out in this article from Atlantic CityLab:

My utopian vision of how this could play out is to rededicate a lot of space in cities that was de facto applied to cars in the 1950s, after the death of the streetcars and the explosion of expressways, over to active transportation. Cars entering city limits would have to be autonomous or switched to driverless mode, as these will be deemed safe for all users of the transportation system and will operate in much less road space than drivers need now. (As a reference point, auto accidents are the leading killer of young people worldwide.) Parking needs could decrease dramatically, too, as most autonomous vehicles will be on-demand and active, compared to the 95 percent of time that current cars sit parked. We would have a transit backbone consisting of heavy and light rail/streetcars, and regional/arterial buses. The rest of the network and space would be slanted towards walking, bike-share, and other alternative modes.

I don’t necessarily think this is a “utopian vision”. I think a lot of it is just going to happen and is already happening. Enormous amounts of space that have been devoted to car maneuvering and parking are going to be available for other uses. The question is, are we just going to let all the space sit there or have a good plan for what to do with it? Some of it can be used for housing and economic activity, some for parks, wildlife habitat and movement corridors, and food growing, and some for managing water or harvesting solar energy. And of course, combinations of these are possible. But we do need to have a vision and a plan, which some can call “utopian” if they so choose.

falling fruit

This website, called Falling Fruit: Mapping the urban harvest, is attempting to be a worldwide map of harvestable food in urban areas. I think this is a great idea both for sustainability and for livability in urban areas. There must be a lot of fruit and nut trees on private land and in forgotten spaces of public land – median strips, the “tree lawn” between street and sidewalk, and so forth. But in many cases the people who own or control this land may not be interested in taking care of these trees. At the same time, I believe there are a lot of frustrated urban armchair gardeners out there who would love to take care of them, but don’t have permission to access the private property, or don’t know about or feel comfortable taking care of the trees on the public property. So a website like this could begin to connect the trees to the people who are willing to take care of the trees.

That’s just the trees we have now. If something like this took off, we could gradually replace more of our ornamental urban landscaping with edible landscaping – fruit hedges, strawberry lawns, and so on.  We could incorporate rain barrels, rain gardens, compost bins, even chickens and rabbits for people who are open to that. We could take wildlife habitat into account to, and start to take a larger view of the landscape – how patches of urban habitat can be connected, and how patches of urban habitat can be connected to larger urban parks and rural reserves.

By the way, I don’t mean for urbanism to be the primary subject of this blog. The subject is how our civilization is connected to, and impacting, and dependent on, the natural world and what that means for the future. But at the risk of stating the obvious, urban areas are where the people are so I will return to urban design and urban hydrology and urban ecology and land use and transportation topics fairly often.
