GRAP 3 restrictions were revoked earlier this month after the air quality improved; however, several preventive and control measures under GRAP 1 and 2 continue across the NCR.

According to the DMRC, the initiative is aimed at strengthening first- and last-mile access to the metro network and addressing the growing concern of air pollution in the city by promoting the use of environment-friendly and efficient modes of transport, as reported by PTI.
