A METHOD FOR ESTIMATING AND GRAPHICALLY COMPARING THE AMOUNTS OF AIR POLLUTION EMISSIONS ATTRIBUTABLE TO AUTOMOBILES, BUSES, COMMUTER TRAINS, AND RAIL TRANSIT

An analytical method is described for estimating and graphically comparing the amounts of mass emissions from automobiles, buses, commuter trains, and rail transit given the emission characteristics of each type of vehicle. Emissions considered include carbon monoxide, hydrocarbons, nitrogen dioxide, and sulfur dioxide. These mass emissions are expressed in grams per person mile as well as grams per vehicle mile in order to consider their quantity based on the movement of people as well as on the movement of vehicles. The relative effects of these pollutants are also presented. Information from this method can be used to estimate the quantity of emissions produced in a specific area given the travel characteristics of that area. Changes in the amount of emissions resulting from persons who change their mode of travel can also be estimated. Application of this method for a given region can help local officials estimate the effects of various transportation policies on the regional transportation-related pollution.
