Old Delhi has 30,000 free-roaming cows and some of the worst traffic in India. We didn't try to remove the cows — we put them to work. Traffic Gaaye turned the city's most unpredictable obstacle into its smartest navigation tool.

01 / Challenge
Old Delhi's roads carry over 96 lakh vehicles across 33,198 km of road network — and roughly 30,000 sacred cows roaming freely among them. Cows are culturally revered and cannot be moved. They slow lanes, block junctions, and create unpredictable bottlenecks that no standard traffic app accounts for. The challenge was to find a solution that respected the culture while actually solving the problem.

02/ Idea
Rather than treating the cows as an obstacle to work around, we made them part of the solution. By equipping cows with GPS-enabled collars, they became live data points — transmitting their position in real time and revealing the hidden lanes and gullies they naturally use to move through the city. Routes no map had ever captured. We then put that data directly in commuters' hands through a mobile app, letting them navigate with the cows instead of against them.
03 / Execution
PixelPlusMedia designed the overall system architecture and built the Cowbell hardware — a transmitter collar housing a recycled smartphone powered by a solar charger. The phone's GPS tracked each cow's position in real time, feeding live data into the system. Mobiiworld developed the app and backend: the Traffic Gaaye app, published on Google Play under PixelPlusMedia, was built on the Google Maps open API — showing live cow locations, sending traffic alerts, and surfacing the hidden routes cows use to move through Old Delhi's oldest streets. The app went live on April 7th, 2016.
04 / Results
Traffic Gaaye didn't just give people an app — it changed how they moved through the city. Commuters started following cow routes, discovering faster paths through streets that didn't exist on any other map. Congestion fell. So did fuel consumption and air pollution.
