Plans for real megalopolis in China

Posted on by

The idea of a megalopolis dates back to the middle 1900s when people started thinking that collections of large cities, such as the large American cities on the Eastern seaboard including Boston, Hartford, New York City, Philadelphia, Baltimore, and Washington D.C., such be considered as a larger grouping. But even this good example has cities separated by decent distances.

China is planning its own version of a megapolis near Hong Kong. The plans including merging nine cities with a combined population of 42 million:

The “Turn The Pearl River Delta Into One” scheme will create a 16,000 sq mile urban area that is 26 times larger geographically than Greater London, or twice the size of Wales.

The new mega-city will cover a large part of China’s manufacturing heartland, stretching from Guangzhou to Shenzhen and including Foshan, Dongguan, Zhongshan, Zhuhai, Jiangmen, Huizhou and Zhaoqing. Together, they account for nearly a tenth of the Chinese economy.

Over the next six years, around 150 major infrastructure projects will mesh the transport, energy, water and telecommunications networks of the nine cities together, at a cost of some 2 trillion yuan (£190 billion). An express rail line will also connect the hub with nearby Hong Kong.

“The idea is that when the cities are integrated, the residents can travel around freely and use the health care and other facilities in the different areas,” said Ma Xiangming, the chief planner at the Guangdong Rural and Urban Planning Institute and a senior consultant on the project.

This sounds like a sizable project. The article suggests that this is being done for several reasons: to achieve economy of scale in certain things (like medical services) and the ability to create unified policies for the region (including transportation and pollution initiatives). And this grouping of cities could conceivably grow even larger if Hong Kong was ever added to this mix.

The article calls this a “mega city” but I think it would fit the definition of a megalopolis perfectly. In fact, compared to most examples of a megalopolis, this one would be much better suited to the idea: the cities are relatively close and will be highly connected. Additionally, the cities are laid out more in a circle pattern rather than a line, allowing a variety of connections between urban centers.

I wonder how many planners around the world would approve of such a project. Combining certain infrastructure has its appeal as planning can be done on a broader scale and without cities constructing competing systems.

Interestingly, there are no plans to give the region a new name: “It will not be like Greater London or Greater Tokyo because there is no one city at the heart of this megalopolis.” Will future residents identify themselves as residents of the region or their specific city?

The problems in one of the best American communities, Falls Church, VA

Posted on by

Newspaper editorials or commentary that discuss how wonderful a particular community is can be interesting. I recall one humorous article about Naperville from the early 2000s that defended the community for “wanting the best.”

This editorial about Church Falls, VA moves from the positives to things that still need to change:

With the release of data by the U.S. Census Bureau, it is now official. As we reported in last week’s edition, the City of Falls Church is officially Number One in the entire U.S. of A. in the categories of median household income, and percentage of the adult population with college and post-graduate degrees.

These statistics don’t lie, although some could argue that degrees in political science and sociology aren’t of the same gravitas as physics or biology. But still, given that it’s lawful that political majors are more prominent here, given our proximity to the nation’s capital where almost everyone works, the puzzle is all the more pronounced.

It’s this: How can the smartest, most politically savvy, best-off people in the nation turn out barely a quarter of its registered adult population to vote in local elections?…

Then there is the issue of affordable housing and a serious commitment to diversifying the community, economically and socially. Clearly, being “well off” financially does not correlate with generosity. This City’s leadership has permitted embarrassing repudiations of these principles, in practice, and no one seems to mind.

Of course, the school system in Falls Church is second to none, but not without a ferocious struggle by administrators, teachers and staff to maintain it in the face of recent years’ funding scale backs, and if that process continues, something is going to give fairly soon.

Even as the schools’ quality is above reproach, however, the issue of the well-being of the students in it, operating as they do under enormous pressure to perform at a high level in academics, athletics and everything else…

If that’s the case, then it may be that a lot of people in Falls Church should be reassessing their priorities in life.

From the outside, it looks like a town filled with self-indulgent people who care for nothing but their home values, on the one hand, and their kids’ SAT and other test scores, on the other. And this, ladies and gentlemen, this is the crème de la crème of America.

Several quick thoughts about this editorial:

1. This editorial comes off as fairly negative. Do the majority of Falls Church residents agree with this assessment about things that need to change? Or is this newspaper arguing for more than the community would be willing to tackle?

2. Is the concern over these issues the mark of a well-educated, wealthy community? If these are the primary concerns and things like a lack of jobs, bad schools, crime, high taxes, and stretched local budgets are not really an issue, then this community is indeed in good shape.

3. The quip that “political science and sociology aren’t of the same gravitas as physics or biology” is intriguing. What exactly do they mean? People take biologists and physicists more seriously? They are seen to be doing “real science” versus interpretation or commentary? They make more money and therefore deserve more respect? And this comes from a newspaper that admits that political science degrees are more prominent due to its location near Washington, D.C.

Looking at the educationally rich Washington D.C. metro area

Posted on by

Based on recently released figures from the 2009 American Community Survey, the Washington Post describes the Washington D.C. metropolitan area, the most educated region in the country:

The data, drawn from questionnaires, underscore the academic primacy of the Washington area: 47 percent of adults – or nearly 2 million – hold bachelor’s degrees, the highest rate among the nation’s large urban areas. Six of the 10 best-educated U.S. counties are within commuting distance of the District.

Half of all degrees in the region are in natural and social sciences, well above the national average, under a broad Census Bureau definition of “science” that includes everything from nuclear physics to sociology. That’s a starting point for looking at variations within the region: So-called hard sciences reign beyond the Beltway, soft ones within.

There are some other interesting facts in here as well, such as the finding that the proportion of people of business degrees in the region is lower than the national average.

What I would be interested to know is how these statistics change the day-to-day lived experience of an average resident of the region. Are there more civic events with more involvement from nearby residents? Is there a large perceived gap between the lives of those who are well educated and those with less education? Do people strike up deeper conversations at any gathering? Does this concentration of people lead to more interdisciplinary work and research?

Shopping malls and noise devices to discourage loitering

Posted on by

A shopping mall in Washington D.C. has installed a noise device, the Mosquito, to discourage loitering:

The owners of the Gallery Place commercial strip have installed an anti-loitering noise device — one to discourage any loiterers, not just teens. Gallery Place has further urged the D.C. Council to pass an anti-loitering ordinance, something the city currently lacks.

Youths in particular are said to be sensitive to a greater range of high-pitch sounds. But Gallery Place Partners, LLC, insists they did not install the “state-of-the-art safety feature” to target teens alone. According to Gallery Place, the Mosquito installed in the Metro plaza is set to a tone that can be heard by people of all ages.

I recall reading that prior attempts to install such devices were accused of being targeted at teenagers because they can better hear and are therefore more annoyed with high-pitched noise-making devices. It sounds like this shopping center is pitching the device as a boon for all users – but are teenagers still the main target?

But this is also a reminder that shopping malls are not public spaces. Even though they are often function as such as place with crowds gathering just to hang out, they are privately owned and the owners are ultimately interested in making money.

Bonus: a link at the bottom of the news story to that takes you to the makers of the Mosquito where you can then find how annoying you find the Mosquito!

Another debate over Washington crowd estimate

Posted on by

The actors are different but the question is the same: just how many people attended Glenn Beck’s “Restoring Honor” rally over the weekend in Washington, D.C.?

This is not an isolated question. The National Park Service bowed out of official estimates back in 1997:

The media, in years past, would typically cite the National Parks Service estimate, along with the organizer’s estimates (which tend to be higher). But the Parks Service stopped providing crowd estimates in 1997 after organizers of the 1995 Million Man March assailed the agency for allegedly undercounting the turnout for that event.

So various media outlets (and interested parties) are now left making competing estimates based on aerial photos, how much space a person typically takes up, and other sources.

There has to be a better solution to this problem.

Predicting future crimes

Posted on by

Professor Richard Berk from the University of Pennsylvania has developed software that predicts which criminals on probation or parole will commit future crimes. His software is already being used in Baltimore and Philadelphia and soon will be used in Washington, D.C.

Here is a quick description of how the algorithm was developed:

Beginning several years ago, the researchers assembled a dataset of more than 60,000 various crimes, including homicides. Using an algorithm they developed, they found a subset of people much more likely to commit homicide when paroled or probated. Instead of finding one murderer in 100, the UPenn researchers could identify eight future murderers out of 100.

Berk’s software examines roughly two dozen variables, from criminal record to geographic location. The type of crime, and more importantly, the age at which that crime was committed, were two of the most predictive variables.

Of course, there could be some problems with this:

But Berk’s scientific answer leaves policymakers with difficult questions, said Bushway. By labeling one group of people as high risk, and monitoring them with increased vigilance, there should be fewer murders, which the potential victims should be happy about.

It also means that those high-risk individuals will be monitored more aggressively. For inmate rights advocates, that is tantamount to harassment, “punishing people who, most likely, will not commit a crime in the future,” said Bushway.

“It comes down to a question of whether you would rather make these errors or those errors,” said Bushway.

I would be curious to see reports on the effectiveness of this software over time. And determining whether this software is effective in areas like reducing crime would present some interesting measurement issues.
