Hexa City, a IP registerd concept by Meta Arch, redefines urban planning with its focus on signal-free junctions. By utilising hexagonal clusters, the design eliminates traditional traffic signals at intersections, allowing vehicles to flow continuously and reducing congestion. This modular, signal-free design saves time, reduces fuel consumption, and encourages walking. Hexa City, with its efficient geometry, offers enhanced traffic flow, sustainable infrastructure, and better mobility, transforming how we design cities for the future.
