• Abstract:
  Illinois Carbon Monoxide Screen for Intersection Modeling (COSIM) Version 3.0 is a Windows-based computer ; program currently used by the Illinois Department of Transportation (IDOT) to estimate worst-case carbon ; monoxide (CO) concentrations near signalized intersections in Illinois. Modeled results from COSIM are based ; on the U.S. Environmental Protection Agency’s (EPA’s) mobile source emission model, MOBILE6.2, and ; roadway dispersion model, CAL3QHC v 2.0. Emission factor (EF) tables derived from MOBILE6.2 are ; incorporated directly into COSIM’s program coding. Recent regulatory changes in mobile source emissions ; modeling have prompted IDOT to update the EFs used in COSIM with EFs estimated using EPA's Motor Vehicle ; Emission Simulator (MOVES) mobile source emission model. This report documents the changes made to ; COSIM, Version 3.0, that allow IDOT to continue to use COSIM (Version 4.0) to estimate worst-case CO ; concentrations for proposed roadway projects with signalized intersections in 2013 and beyond.
