Estimated Air Pollution & Health Benefits of Metro System in Delhi, India
The impact of air pollution on the human health and the ecosystem is increasingly been linked to the growing transport sector. A major intervention that Delhi is counting on is the extension of the metro rail system, to shift the motorized transport trends to the metro rail. The expected level of shift is uncertain, which depends on a number of factors. A prelimiary analysis was conducted in 2008 and this paper extends the analysis to estimate the potential air pollution and health exposure benefits under multiple scenarios of traffic patterns in Delhi.
