"Falls are the second largest cause of accidental injury in the U.S. Based on the reports to the Federal Railroad Administration, the U.S. rail industry carried 7.25 billion passengers during the period 1976-1980, and these patrons experienced about 10,000 station falls. Analysis of accident reports in one system shows alcohol involvement in 29 percent of all falls and 55 percent of male falls where an ambulance was called. Off-peak incident rates were higher, and the P.M. peak is higher than A.M. Most transit falls are due to personal factors. Station falls cost the transit industry an estimated $1.7 million annually in claims settlements. Societal cost for lost time and hospitalization are about the same. High industry standards of design and maintenance result in lower incident rates and settlements than the general experience. Design improvements are warranted to reduce incident rates, severity, and claims."
