Pune's 125-junction adaptive signal grid needed a ₹30 crore emergency fix two years after launch before PMC's own numbers — 15% less congestion, 70% no-stop junctions — started to hold, and monsoon rain still breaks it.

Pune Municipal Corporation modernised signals at 125 junctions under an Adaptive Traffic Management System launched in 2022, adjusting green-light timing to real-time traffic density and feeding central monitoring at the ICCC. The rollout was rocky: glitches and complaints forced repeated PMC-police-Smart City review meetings, and PMC paid the contractor an extra ₹30 crore in 2024 to fix performance, on top of ₹133 crore for installation and ₹52 crore for maintenance. Since the fix, PMC-cited figures put congestion down about 15% and average speeds up about 10% on covered corridors, with roughly 70% of vehicles clearing junctions without stopping — though the system still degrades in the monsoon.
📊 Impact
Press-reported PMC figures after the 2024 fix: about 15% less congestion and 10% faster average speeds on key roads, with close to 70% of vehicles passing junctions without stopping.
🎓 Lesson
Launching an adaptive signal network is not the same as running one — Pune's system needed two years of complaints and a second, ₹30 crore contractor payment before its performance claims held up.
