However, if traffic diminishes, bikes might come to dominate roads.

The six or so main districts are *really* populated--parts have population densities of over 145,000 people per square mile. It truly is one of the most densely populated places in the world.<br /><br />http://www.newgeography.com/content/002708-the-evolving-urban-form-hong-kong<br /><br />Paris has a population density of 55,000 per square mile. Manhattan has a population density of 70,000 per square mile; Brooklyn has a density of 36,000; Chicago has 12,000. San Francisco has a population density of 17,000 per square mile, but it varies considerably by neighborhood. (Parts of Chinatown in San Francisco have densities over 90,000 per square mile.)<br /><br />Most of the cities likely to benefit from Millenials going car-free are not that large and are already fairly dense and compact. Boston, for example, would only have to gain 300,000 people to reach a population density of 20,000 per sq mi (Parts of Boston are already at this density.) Cambridge, next door to Boston, would only have to add 26,000 people. Miami would have to add 334,000; San Francisco would only need to gain 140,000 more people. So reaching the density I'm talking about would require less population movement in the US than you might expect. If only 2% of the US population wanted to move from the suburbs to car-free cities, that would be 6.3 million. This 6.3 million would easily fill up the twelve likely car-free city candidates.Karen Lynn Allenhttps://www.blogger.com/profile/01570980995774757572noreply@blogger.comtag:blogger.com,1999:blog-8731149177870823280.post-18341242873923689992013-04-19T12:41:52.325-07:002013-04-19T12:41:52.325-07:00well i think that your claim
"that by the end...well i think that your claim<br />"that by the end of 2015 successful cities will be largely car-free."<br />is really quite astonishing. <br />the graphs you made are very interesting (a good graph says more than a thousand words).<br />in europe also the sales of cars are down quite a lot, and hence also the consumption of energy.<br />however, i'm not sure how much this drop of consumption can go on relatively smoothly?<br />when does it start disturbing the basic<br />mechanisms of the (consumer) society?<br /><br />however,<br />"at least 10,000 – 15,000/sq mile in some part of their urban core... In Europe this would describe almost every city over 200K in population"<br />"Convenient car-free living takes a population density of roughly 20,000/sq mile."<br /><br />where do these numbers come from? i think they are really funny, even hongkong has less than 20000...<br /><br />http://en.wikipedia.org/wiki/List_of_countries_by_population_density<br /><br />perhaps the solution is to increase the population so that it becomes more dense...<br /><br />here in finland the capital helsinki<br />is really very far from this: only about <br />7000 <br /><br />http://fi.wikipedia.org/wiki/V%C3%A4est%C3%B6tiheys<br /><br />about half of the people should live in the capital to meet these requirements. <br /><br />so these kind of densities would need massive displacement of people, and also massive construction of new infrastructure. <br />so it's hard to believe that the situation would change that much by 2015.<br /><br /><br /><br />Anonymousnoreply@blogger.com
