In order to quantify the benefits of public transit to non-users in the Manhattan Central Business District, several scenarios were developed. In one scenario where the CBD was entirely dependent on vehicle entries, the density of the CBD was limited to 20 percent of the present level. Therefore, 80 percent of the current business activity and tax revenues in the area could be ascribed to the public transit system. In the second scenarios, 10 percent shift of the current subway and bus commuters to automobile use occured. This caused street and river crossings to be filled to near capacity during rush hours. Employing this assumption, it is possible to observe the impact of the public transit system on an entire class of street users (e.g. cabs, motorists, truckers) with regard to increased travel time, travel cost and fuel consumption and pedestrians and other street users with regard to air pollution. The third scenario analyzed the adverse effects on the metropolitan New York area (e.g. increased fuel consumption, higher accidents rate) caused by the dispersion of the Manhattan CBD assumed in the first scenario. The information generated by these scenarios tend to support the contention that general revenue subsidies should be utilized to support public transit.
