According to this article, levels of PM10/2.5 particles are as high as 400 µg/m³ in Beijing. This is 10 times the European limit. What is the cause of this? Beijing has a lot of traffic, construction, factories and power plants, but I assume the levels are not always this high. Is this a stagnant airmass against the mountains? That could include sources in the Tianjin area (20+ million people).

The common cause is coal burning as a heating source.

Changchun, Jinan, Zhengzhou, Chengdu, Xi'an and Urumqi are just as bad ( see http://www.aqicn.info/?map ).

Interestingly, Tianjin and Chongqing's readings are similar to Hong Kong.

As far as I can remember there was no-cars-allowed restrictions for the Olympics period in 2008 so the heavy smog over Beijing can clear out. And yes ... the main reason for the dust over-dosages in the atmosphere is because china's economy is very dependent on coal as an energy resource...

Pipeline plans could also damp imports: a big Chinese-funded gas pipeline between Burma and China is due to be completed in 2013; the pipeline from Turkmenistan is set to expand; and Beijing and Moscow are locked in negotiations over a new Russia-China gas pipeline as well.

It amazes me that China has grown as it has and the highways in this thread impress me. I am just in sheer, utter awe over these roads. BTW, I just joined so I can comment on the pics and participate here amongst other fans of roadways from around the world!

China really has built itself up from the ground in a way that kind of scares me. I mean- even the US Interstates didn't go up this fast! WOW.

When looking at especially China always convert to per capita numbers when comparing totals. There is lots to be impressed about but when you look at say 2,500km of motorways being built that is around the same as 19km being built in Czech republic as a example. (1/130th the population).

So its actually right around the mark that you would expect a developing country to be (could be higher actually although the risks of major system failures would increase further), only difference being that China holds 20% of the planets population and has a government that controls the flow of information and has reasons to help propagate a positive global perception regarding China even further.

I do love the pics and updates though, people just have to put things in perspective and not fall for the hype train when checking it all out.

i think per square meter make more sense than per capita numbers, you build 1 highway to link one town with 1000 people, you still just need to build 1 highway to link a town with 10 000 people not 10 highways

Depends on the population density too. and the strategic natural and geopolitical situation of the area...

So how big a highway network does China need? Also, given rising fossil fuel prices, pollution, the shrinking agricultural land area, should China keep on building highways? Isn't it time to look beyond the automobile as a means of transport? And if so, what would take its place?

Are highways not suitable for electric or hydrogen powered cars?

I agree fully with you. But it raises the pertinent question, how big a highway network does the PRC need? Should it focus henceforth more on railway expansion? Or rural roads?

Good point. Honestly, it hadn't struck me. My point was three fold: one , will expansion of highways reduce agricultural land and hence at some point threaten food security, second, how does China ensure that those who cannot afford cars still get benefitted, third, China should ensure that the mistake USA did, to build everything around the automobile is not repeated.

But as an Indian and lover of infrastructure, I have to say: China's infra development, be it rail or road makes me

Currently there is globally enough oil for 40 years. Given that average life time of a cars is around 10 years we can all think about how long would it take at current tempo to change into oil fuel independent cars... This puzzle doesn't have nice and simple solution. And thats only about the automobiles, don't forget all the other industries.

However, I normally prefer when the exit lane separates earlier.

Love the fact that the exit has a hard shoulder by the way.
