A Software Model for Transportation Emission Inventories
This thesis describes an on-road vehicle emissions and fuel consumption (E&FC) inventory model named CALMOB6. It is destined for use by traffic planners who need such a tool primarily to measure the effect of any traffic control measure they take on E&FC. CALMOB6 combines data from the transportation model EMME/2 and the vehicle emissions model MOBILE6 to generate criteria and greenhouse pollutants inventories on a second-by second basis. Being CALibrated to MOBILE6, CALMOB6 can estimate past, current and future emission levels. Similarly, it uses fuel consumption trends from Natural Resources Canada for the light-duty fleet and from Environmental Protection Agency for heavy-duty vehicles. E&FC can be estimated on any scale from an entire regional fleet down to a single road, on a defined time scale and for a particular vehicle subclass. The model is sensitive to local geographic and local meteorological parameters and accounts for the effect of cold-started, alternatively-fuelled and super-emitting vehicles.
