Cities that average more than 50 annual transit trips per capita have about half the average traffic fatality rates as cities where residents average fewer than 20 annual trips. Since Americans average about 1,350 annual trips on all modes, this increase from less than 20 to more than 50 annual transit trips represents a small increase in transit mode share, from about 1.5 percent up to about 4 percent. That equates to an increase in transit mode share of less than 3 trips a month per person. http://bit.ly/2cm4tw9
