As the commercial and political center, the city center will be surrounded by the agricultural area, residential area, industrial area and recreation area. They form a perfect life circle. In the future cities, there are fast tracks among those areas, and solid shield to block outside invasions. Instead of people, the artificial intelligence will control the operation of the cities. Instead of people, the unmanned vehicles, aircrafts and ships will be the most popular transportation means. They are quick and safe. |
