GFA and Transportation

 

This brilliant matrix provides a cheat-sheet for urban managers to set their baseline thoughts. For long, the attractive CBD disturbs the proper planning and distribution of GFA and Transportation along the city, which always creates congested nodes that are volatile, chaotic and inhumane. Yet, the domestic business landscape find it hard to relocate to the suburban business parks. However, without a firm-but-well-planned strategies, the dilemma would continue.

Thank you for sharing this. While some cities demonstrate high-density land use, some rely on dendritic (hierarchical) roadway networks. These systems funnel traffic into a few major roads, making them auto-oriented and less walkable, with public transit often serving mainly the captive users.
The success of public transit lies in shifting auto users to transit. A key factor in achieving this is gridded networks with narrower roads and smaller blocks that promote walkability and mixed-use development, which are essential for increasing transit use.
In contrast, dendritic systems often segregate land uses, with residential areas clustering around local streets and commercial zones near expressway interchanges, reinforcing auto dependency. Without a gridded framework (regular or irregular grid), mixed-use development struggles to thrive.
In summary, narrower roads, small blocks, density, and mixed-use development are critical to reducing auto dependency and encouraging transit use. Notably, some cities are now experimenting with high-density sprawl, but without the right mix of land use and the right narrow and grided roadway framework, public transit remains ineffective in these areas.
