PRELIMINARY STUDY OF MODELING THE AIR POLLUTION EFFECTS FROM TRAFFIC ENGINEERING ALTERNATIVES

THE DYNAMIC HIGHWAY TRANSPORTATION MODEL, AN EMISSION MODEL, AND THE APRAC-1A URBAN DIFFUSION MODEL WERE COMBINED TO CALCULATE THE CHANGES IN CARBON MONOXIDE CONCENTRATIONS THAT MIGHT RESULT FROM TRAFFIC ENGINEERING CHANGES. THE COMPOSITE MODEL WAS APPLIED TO TRAFFIC IN DOWNTOWN CHICAGO FOR A SPECIFIC SET OF METEOROLOGICAL CONDITIONS. RESULTS ARE COMPARED FOR TWO TRAFFIC SIGNAL CONTROL SCHEMES. IN THOSE BLOCKS WHERE CONCENTRATIONS WERE HIGHEST, THE MODEL INDICATES A 20 PERCENT REDUCTION IS POSSIBLE THROUGH IMPROVED TRAFFIC SIGNAL CONTROLS. /DOT/
