The most significant role played by Le Corbusier in Chandigarh was in conceiving the city's present urban form. It is the well-ordered matrix of his generic ‘neighborhood unit' and the hierarchical circulation pattern of his ‘7Vs' that has given Chandigarh its distinctive character. The Matrix comprises a regular grid of the fast traffic V3 roads which define each neighborhood unit, the ‘Sector'. The Sector itself was conceived as a self-sufficient and - in a radical departure fr om ot her pr ecedent s and cont empor ar i es concepts - a completely introverted unit, but was connected with the adjoining ones through its V4 - the shopping street, as well as the bands of open space that cut across in the opposite direction. Day-to-day facilities for shopping, healthcare, recreation and the like were arrayed along the V4 - all on the shady side. The vertical green belts, with the pedestrian V7, contained sites for schools and sports activities.
