In Ryan’s blog, he mentions the spread of private car ownership which started in 1960s, it brought convenience to the daily lives of people. But at the same time, it caused a lot of problems such as; air pollution, noise pollution and they all have negative effects on peoples health. Ryan then focused on the negative impacts from motor vehicles. Its well known that pollutants emitted from motor vehicles such as, Nitrogen Oxides, Carbon monoxide, Volatile organic compounds, Fine particulate matter and Ground-level ozone are all dangerous. Furthermore he also mentioned three kinds of sustainable transport which can be benefit to people’s health.

I totally agree with Ryan’s position of encouraging sustainable transport. Besides the issue of pollution from motor vehicles, but people have still become reliant on vehicles. People are apposed to walking or cycling even if the distance is short, meaning there are more cars on the road which leads to more traffic jams. This phenomenon is especially serious in China, So the government has taken a lot of actions to reduce this position.

  • Case study: Public Bicycle System in Beijing

“Public bicycle has become a kind of short-distance means of transport which is viewed as a low-carbon environment-friendly, economical and convenient, healthy fashion to overcome the influence of global warming.”( Liu, Jia and Chen, 2012)

This bicycle system was originally conceived to solve the “last mile” problem and connect users to public transit networks. In Beijing, all the public bicycles can be used for free which is an efficient way to encourage people choose bicycles instead of motor vehicles.

After this system was put into use, most of the residents were willing to use it. “In Chaoyang district for example, the bicycles have been used for more than 920,000 times from June 2012 to June 2013 and the daily rental frequency is around 3,000 to 4,000.”(Qian, 2013)

Overall, this form of sustainable transport is becoming popular among Chinese cities. And with the further development, “it has potential to be continuously better integrated into the overall public transport network.” (Qian, 2013)
