The Nagpur plan formulae assumed a star and grid pattern.

The Nagpur plan formulae were developed by architect Charles Correa for the city of Nagpur in India. These formulae aimed to provide a comprehensive and flexible approach to urban planning that could accommodate the rapid growth and changing needs of the city.

Star Pattern:
The star pattern refers to a layout in which major roads radiate outwards from a central point, like the spokes of a wheel. This pattern is often used in urban planning to create a well-connected and easily navigable road network. The Nagpur plan formulae assumed a star pattern as a basis for the city's road network.

Grid Pattern:
The grid pattern, on the other hand, refers to a layout in which streets intersect at right angles, forming a rectangular grid. This pattern is commonly used in urban planning to create a regular and organized street network. While the Nagpur plan formulae did not assume a grid pattern as the primary layout, it incorporated elements of both the star and grid patterns to create a hybrid approach.

Combination of Star and Grid:
The Nagpur plan formulae combined the star and grid patterns to create a unique urban planning strategy. The central area of the city was organized in a star pattern, with major roads radiating out from a central point. This allowed for efficient connectivity and easy access to key destinations within the city.

At the same time, the Nagpur plan formulae incorporated a grid-like structure in the outer areas of the city. This grid pattern served as a framework for future development and expansion, ensuring that new developments could be easily integrated into the existing road network.

The combination of the star and grid patterns in the Nagpur plan formulae provided a balance between efficient connectivity and future flexibility. It allowed for the growth and evolution of the city while maintaining a cohesive and well-planned urban environment.

In conclusion, the Nagpur plan formulae assumed a star and grid pattern, combining the strengths of both layouts to create a comprehensive and adaptable urban planning strategy for the city of Nagpur.
