Traffic Volume Surveys

Two traffic surveys, thirteen years apart, capture how vehicle volumes shifted across Pimpri-Chinchwad and the wider Pune metropolitan area.

2008: PCMC Baseline

The 2008 Comprehensive Mobility Plan survey measured traffic at 15 locations across PCMC. It established key patterns: NH-4 corridor dominance (Dapodi Bridge at 1.2 lakh vehicles/day), two-wheeler dominance on internal roads (50-54% share), and sparse traffic on the northern periphery (Dehu-Alandi at under 10,000 vehicles/day).

2021: Metro-Wide Update

The 2021 Metro DPR traffic survey expanded coverage to 82 locations across PMC, PCMC, and outlying areas. The PCU/Vehicle ratio at each point reveals the vehicle mix — ratios below 0.85 indicate two-wheeler dominant traffic, while ratios above 1.1 indicate heavy vehicle corridors.

What Changed

Four locations can be matched between the two surveys. The results suggest traffic redistribution rather than uniform growth:

• Dapodi Bridge: -58% — NH-4 traffic dispersed to parallel routes
• Harris Bridge (Bopodi): +265% — absorbed traffic displaced from Dapodi
• Aundh Bridge: +31% — moderate growth on the Aundh-Ravet corridor
• Nashik Phata: +65% — reflects development of PCMC's northern corridor

The pattern is clear: the city's traffic arteries shifted. The once-dominant Dapodi Bridge corridor lost traffic to a wider network of crossings, while PCMC's expanding northern periphery grew substantially.
