Delhi/NCR vehicle speed data gathered using GPS

New Delhi: A recent study by a research group, UrbanEmissions.info, has found that a fifth of a car’s traffic time in Delhi is spent idling or crawling at less than 4 kmph due to heavy congestion on roads and too many signals. The speed data across the NCR was collected by students of IIT equipped with GPS devices. So far, they have logged 120 hours on the road traveling to Noida, Greater Noida, Gurgaon, Dwarka and across South Delhi. They plan to collect data for around 1,000 hours of motoring.

Sarath Guttikunda, co-director of UrbanEmissions.info, stated that “We use an algorithm in the GIS to merge data and map it,” said Sarath Guttikunda, co-director of UrbanEmissions.info.

The study is being conducted with an aim to understand how the city drives – its acceleration and deceleration pattern. “This would also give us an idea of real-time emissions and our exposure to pollution. We would get a clear picture at the end of six months when we complete the study.” Guttikunda added.
