The movement of persons into lower Manhattan during a typical business day increased from 3,271,000 in 1940 to 3,765,000 in 1948.
This is disclosed by a study based upon the traffic data provided through cooperation of the Port of New York Authority, various New York City agencies - Police, Public Works, Board of Transportation, Triborough Bridge and Tunnel Authority, private bus lines and railroads.
Through the assistance of all these agencies it has been possible to collect and compile statistics of all passenger movements in vehicles on surface streets as well as in subways and on railroads and ferries into lower Manhattan (south of 61st Street) on a typical business clay in 1948.
Together with similar statistics compiled previously by the Regional Plan Association for typical business days in 1924, 1932 and 1940, it is possible to continue the study of significant trends.
