"Around the world, nations are grappling with the challenge of planning for the cities of the future. The forces of the global economy are driving rapid urban growth and requiring governments to rethink their approach to the planning and development of cities. ..."You can comment on the article, or read those of others. In my comments, I agree with most of the PM's article, but have suggested that the Internet needs to be incorporated in city planning. Projects such as the NBN will change the shape of cities. The Internet can be used to improve public transport and combat climate change, but this needs to be incorporated into city planning to have the maximum benefit.
Examples of the Internet effecting cities are the use of WiFi on public transport increasing the acceptable journey time for commuters and the use of web booking for car share services. These are examples of changes which can be made to transport system much quicker and cheaper than building a metro or a hybrid car factory.
