From the two articles that. I think the two projects are similar and have the same purpose. Is to help reduce global warming and energy saving and can reduce traffic problem too .But the different is the operation of these two projects. First article mentioned projects in countries Sweden which way of project I think can encourage people to pay attention to. And see the real project of more than the second article by Article two was used to stimulate the people do not match the purpose of the project as it should be. But no matter how the operation will be different. I think the most important thing is that the results of the project and the benefits that people receive.
