Analysing real-time vehicle speed data from Uber Delhi revealed that during the odd-even program, average speeds went up by a statistically significant 5.4 per cent (2.8 standard deviations from normal). This means vehicles have less idling time in traffic and vehicle engines would run closer to minimum fuel consumption.[9] In bordering areas, PM 2.5 levels were recorded more than 400 (ug/m3) while in inner areas in Delhi, they were recorded between 150 and 210 on an average.[10] However, the sub-city of Dwarka, located in the southwest district, has a substantially low level of air pollution. At the NSIT University campus, located in sector 3 Dwarka, pollution levels were as low as 93 PPM.[citation needed]
