Abstract:

This Technical Note documents the methods the Texas Transportation Institute (TTI) used to develop the Beaumont?Port Arthur ozone nonattainment area (BPA) on?road mobile source actual emissions estimates for the August 2000 ozone episode. (Documentation of the August 2007 base-case episode forecast, also produced under this task, is provided in a separate Technical Note.) The three BPA counties are: Hardin, Jefferson, and Orange. The episode period of analysis is the 11-day sequence, Tuesday, August 22, through Friday, September 1. Emissions of volatile organic compounds (VOC), carbon monoxide (CO), and oxides of nitrogen (NOx), are estimated for each county and day on an hourly basis. The hourly estimates are computed by network links (characterized by 28 facility types, including special intrazonal links) for which geographical coordinates are provided. Emissions are categorized by 28 vehicle types and 14 pollutant-specific emissions types. Documented within are the methods related to calculating inventory elements including link based 2000 vehicle miles traveled (VMT) estimates from the Beaumont-Port Arthur travel demand model (TDM), August day-of-week-adjusted Highway Performance Monitoring System (HPMS) VMT control totals, speeds, VMT mix, MOBILE6 emissions factors, and emissions estimates.
