A smart, sustainable, and linked environmental civilizational future is what the cities of Woven City in Japan and The Line City in the Kingdom of Saudi Arabia want to achieve.Since the city is car-free and has a park, resident recreation spaces, and cutting-edge technologies like subsurface waste disposal systems and self-transportation systems, it was designed with pedestrians in mind.The city has smart dwellings with artificial intelligence and sensor systems for resident safety and comfort, blending residential, commercial, and leisure areas.The Line City is a city that uses artificial intelligence to create a sustainable, urban, and nature-friendly environment that improves the quality of life for its citizens.With 2,000 citizens, the city is comparatively modest in size.
