Interesting twitter deck on
traditional urbanism:
"Traditional urbanism has short blocks. No building takes more than 3-4 seconds to walk past, providing interesting colors, shops, textures....
Modern dis-urbanism means massive buildings, long block: takes minutes to walk past with nothing to distract or relieve the tedium...."
Lots more at the link.
'Traditional' urbanism is still alive and (fairly) well in the UK and Europe more so than in the USA, I think, for a variety of reasons, possibly to do with the former having had in many cases a more compact and intact (despite world wars) 'organic' heritage on which to accrete new or replacement forms. Many North American towns began as planned grids. On top of that, 'middle-class'American suburbanism developed along slightly different lines, with large plots being more commonly aspired to.
Urban environments in Western Europe (even modern ones) have not been 'designed for the car' as much as in the USA. And I think it's also fair to say that many of the examples in the OP link are pre-car.
Europe is nonetheless no haven of traditional, varied, compact urbanism. The car has heavily impacted here too. As has technology. A simple thing like 'maximum span' dictated a lot of 'traditional' urban forms (and this applied to both whole buildings and their components, such as doors and windows).
One emerging trend, which may continue, is that living in (pedestrianised) urban centres may become more fashionable and attractive, as vehicular (or merely long-distance) journeys become more expensive, more environmentally unfriendly and perhaps also because urban centres are changing. Shops are facing a difficult time, partly because of increased internet shopping. More and more land may become available in urban centres and it has been suggested that having more of that land given over to housing, possibly as part of a live/work paradigm (as in the 'old days' when most people lived where they also worked) might be a good idea.
Finally, I think architects and town planners have a lot to answer for, especially since the emergence of (minimal) 'modernism' about a hundred years ago. Buildings and townscapes have often not been designed 'for people' (even though the designers often claim they have). Rather, in too many cases, 'people' are left to wander about in the (often too wide) gaps in between large, plain buildings. One can't blame designers too much though. In the end, an architect more or less has to work from a brief he or she is given by a client, and the economics of large buildings in repetitive, simple forms has meant that clients generally discourage the sort of fiddly, quirky (read: interesting) small-scale designs that are arguably most rewarding to live among.
In other ways, we all to some extent get the sort of buildings and urban landscapes we deserve. If most people go to large, out of town shopping centres because of convenience, value and greater choice, they can't also be surprised if town centres become less appealing visually.
