" The more you densify a city, the more congestion will increase, however technology changes… cities so packed that they will no longer function… vertical sprawl. "
- Leon Krier

The more a city becomes densely populated through urban development, the greater the likelihood that traffic congestion will worsen. This idea suggests that as cities grow and buildings become taller and closer together, movement within these areas can become increasingly difficult due to limited space for transportation infrastructure like roads and public transit systems.

Beyond its immediate implications about physical density and traffic issues, this statement also touches on broader themes of urban planning and the role of technology in mitigating challenges. Leon Krier’s comment hints at a future scenario where cities could reach a critical point beyond which they cease to function efficiently without significant technological intervention or innovative design solutions. The concept of "vertical sprawl" refers to the expansion upwards rather than outwards, creating complex spatial arrangements that traditional urban planning might not fully address. This perspective challenges planners and architects to rethink how technology can reshape city dynamics, perhaps through advancements like vertical transportation systems, smart traffic management, and even reimagining how people live, work, and interact in dense environments.

Leon Krier is a renowned architect and urban designer known for his critiques of modernist architecture and planning principles. His ideas often emphasize traditional town planning methods that prioritize human-scale living and walkability over large-scale development projects that can lead to alienating and congested cities.
