How to Track Delhi Buses Live in 2026: OTD GPS Telemetry, Apps & Accuracy
Inside Delhi’s Open Transit Data platform: how 10-second GPS telemetry works, expected ETA accuracy, crowd rush predictions, and using BusPe for real-time tracking.
- Every DTC and cluster bus transmits latitude, longitude, and speed telemetry every 10 seconds.
- Delhi Government publishes this telemetry publicly under the Open Transit Data (OTD) initiative.
- BusPe ingests these feeds and matches vehicle coordinates against static GTFS route paths to calculate live ETA.
- Live radar displays let commuters spot approaching buses up to 5 kilometers away.
How Delhi Open Transit Telemetry Works
Delhi is the first city in India to mandate open GPS telemetry across its entire public bus fleet. Onboard Automated Vehicle Location (AVL) boxes ping satellite constellations and transmit data over cellular networks to central GNCTD servers.
