The document discusses the challenges facing modern cities, including overpopulation, waste, pollution, and congestion. It proposes solutions for specific problems like implementing renewable energy sources, electric vehicles, and high-speed public transit. The document puts forth a vision of a two-level city with traffic, parking, and waste located underground to address these issues holistically, providing benefits like reduced pollution, noise, and waste while freeing up space above ground for living and recreation.

2. What are the challenges of today‘s cities?
• Increasing no. of world population living in cities
(Today: 50%; 2050: est. 66%)
• Overcrowded inner cities, desolate outskirts
• Large production of waste, waste water and pollution
• High energy and raw material consumption
• Congestions, lack of parkings, smog
• Unacceptable noise level

8. But is there a solution which
solves it all at once?

9. Vision of a two-level city
Above ground: Working, living, recreation
Surrounding:
Energy & raw materials
Under ground: Traffic, parking, waste

10. And the benefits ?
No cars, no waste, no pollution, no noise
Only more recreation time
And for the city probably lower costs
