The toll may produce up to $15 billion for investment within the aging MTA system. For example, particulate matter emissions from stop-and-go traffic can stoke diseases such as asthma. "In London, they've had a reduction of nearly 20% in particulate matter pollution," said Julie Tighe, president of the New York League of Conservation Voters. "There's a 15% reduction in particulate matter in Stockholm, which resulted in a 50% reduction in asthma."
