Key Takeaways
- Chandigarh’s road network follows Le Corbusier’s 7Vs hierarchy, ranking roads from V1 regional highways down to V8 cycle tracks.
- V3 roads form the fast-traffic boundary around each sector, with no building doors opening directly onto them.
- V4 roads carry each sector’s shopping street, while V6 and V7 handle residential access and pedestrian movement.
- This hierarchy was a genuine planning innovation for its time, separating traffic types to reduce congestion and improve safety.
Chandigarh road planning follows a distinctive hierarchy that architect Le Corbusier called “Les Sept Voies de Circulation,” or the 7Vs system, ranking every road in the city from V1 down to V8 based on speed and function. Unlike most Indian cities, where roads grew organically without a unified traffic logic, Chandigarh’s entire network was designed from the outset to separate fast through-traffic from local, pedestrian, and cycle movement. Consequently, understanding this system explains why the city feels notably different to navigate compared to older, unplanned urban centres. This guide breaks down each road category and what it means in practice.
What Is the 7Vs Road System?
Le Corbusier designed Chandigarh’s roads as a biological-style hierarchy, moving traffic through progressively slower, more localised road types as it approaches a destination, rather than mixing all traffic types on the same streets.
V1 and V2: Regional and Urban Arteries
V1 roads are regional highways connecting Chandigarh to surrounding cities and states, carrying the fastest, longest-distance traffic. V2 roads function as major urban arteries, distributing traffic across the city’s different sectors and zones.
V3: Sector Boundary Roads
V3 roads form fast-traffic boundaries around each sector, which typically measures 800 by 1,200 metres. Notably, no building entrance opens directly onto a V3 road, a deliberate safety measure that kept fast through-traffic separated from local access points.
V4: Sector Shopping Streets
Each sector’s V4 road hosts its main shopping street, similar in function to Sector 17’s plaza or Sector 22’s market corridor, giving commercial activity a dedicated, lower-speed road type.
V5, V6, V7, and V8: Local Access and Movement
V5 roads distribute traffic within a sector, meandering rather than running in straight lines to naturally slow vehicles down. V6 roads provide direct residential access, V7 roads are dedicated pedestrian paths, and V8 roads form the city’s cycle track network, completing the hierarchy’s shift from fast regional traffic down to slow, human-scale movement.
Why This System Still Matters
Chandigarh’s road hierarchy remains one of the clearest physical expressions of its planned-city identity, and understanding it helps explain everything from why certain sectors feel quieter than others to why V3 roads can feel disconnected from the buildings around them despite running right past sector boundaries.
| Road Type | Function |
|---|---|
| V1 | Regional highways connecting Chandigarh to other cities |
| V2 | Major urban arteries distributing city-wide traffic |
| V3 | Fast roads forming sector boundaries |
| V4 | Sector shopping streets |
| V5 | Meandering distribution roads within a sector |
| V6 | Residential access roads |
| V7 | Pedestrian paths |
| V8 | Cycle tracks |
Frequently Asked Questions
What is the 7Vs system in Chandigarh?
It is Le Corbusier’s road hierarchy for Chandigarh, ranking roads from V1 regional highways down to V8 cycle tracks based on speed and function.
What are V3 roads in Chandigarh?
V3 roads form the fast-traffic boundary around each sector, with no building entrances opening directly onto them.
Which road type hosts a sector’s shopping area?
V4 roads carry each sector’s main shopping street, similar to Sector 17’s plaza or Sector 22’s market.
Does Chandigarh have dedicated cycle tracks?
Yes, V8 roads form the city’s dedicated cycle track network, part of the original 7Vs planning hierarchy.
Why did Le Corbusier separate roads into different categories?
The hierarchy was designed to separate fast through-traffic from local, pedestrian, and cycle movement, reducing congestion and improving safety.
Are V6 roads used for residential access?
Yes, V6 roads provide direct access to residential areas within each sector.
Chandigarh’s road hierarchy remains a defining feature of the city’s planned identity, shaping everything from traffic flow to how sectors feel to walk through. Whether you are new to the city or simply curious about its design logic, recognising V3 boundaries and V4 shopping streets makes navigating Chandigarh considerably more intuitive.
