What you're solving
Unlocking urban mobility in Bengaluru.
A city of over 14 million people loses billions of hours every year to gridlock. CCTV cameras across Bengaluru monitor congestion, violations, and safety — but most analysis still depends on manual review, limiting speed, accuracy, and scale.
Gridlock 2.0 is Flipkart's call to India's problem-solvers: design AI models that classify congestion, detect safety violations, identify movement patterns, and support smarter urban mobility decisions — built on real data, not simulations.
Your journey
Three phases. Six weeks. One shot at the city.
From online ML challenge to a real-world prototype to an onsite finale at Flipkart HQ — here's exactly how Gridlock 2.0 unfolds.
