The air quality in Delhi-NCR has been at its worst over the past week and the state government is taking dramatic steps to curb the deteriorating air pollution. In a positive step towards the same direction, the Delhi government has initiated the trials of zero-emission and noise-free electric buses in the capital today. Olectra-BYD's 12-metre electric bus - eBuzz K9 will be used for the trials, which has a seating capacity of 35, along with the driver. The made-in-India electric bus will be plying on the roads of Delhi for the next three months, and will give the authorities an opportunity to evaluate the efficiency and competency of these buses in the standard road conditions of the national capital. The Delhi government aims to induct electric buses in the public transportation system, as it promotes the use of electric vehicles.
