Abstract:
This Technical Note is one of two reports which document the methods the Texas Transportation Institute (TTI) used to develop 1999 base case and 2007 future case September/August day?ofweek hourly on?road mobile source emissions inventories for 210 Texas counties. These emissions inventories will be used to photochemically model the August 13 through 22, 1999 ozone episode in the Tyler?Longview?Marshal near?nonattainment area (NNA), and the September 13 through 20, 1999 ozone episode in the Austin, San Antonio, Corpus Christi, and Victoria NNAs.
The 210 counties subject to this analysis are the central and eastern Texas counties. The 44 western counties outside of the Texas NNA modeling domain encompass an area including the cities of El Paso, Odessa, Lubbock, Amarillo, and Big Bend National Park.
There are 18 NNA counties (17 plus Kendall County which was included with the NNA Counties for the purpose of procedure documentation, see Table 1) and 192 surrounding counties in the analysis. For nine of the 18 NNA counties, complete urban travel demand model (TDM) networks are available. These counties are represented in six TDM networks. These networks are Austin (Hays, Travis, and Williamson counties), Bexar, Corpus Christi (Nueces and San Patricio counties), Gregg, Smith, and Victoria. This Technical Note documents the methods TTI used to develop the TDM network link?based emissions inventories for these counties with the complete urban TDM networks. Table 1 shows the NNA counties by NNA and delineates the nine counties with complete TDM networks.
