APPENDIX B: LTPP PLUG DATABASE DATA DICTIONARY

This appendix provides a data dictionary containing field names and descriptions for the tables included in the LTPP PLUG database. This information can aid in understanding the data in the database tables and to facilitate uploading of the additional information (LTPP updates or State-specific information) to the database tables.

Listed below are brief descriptions of the tables present in the database:

ALF_DEFAULT_ALS and ALF_Gen_Axle_Group - These tables are used internally by the LTPP PLUG software to generate *.alf files. Table 21 and table 22 contain the field names and descriptions.
DEFAULT_AxlesPerTruck - This table contains default APCs based on all applicable SPS TPF data. Table 23 contains the field names and descriptions.
DEFAULT_NALS - This table contains Tier 1 or Tier 2 NALS defaults, based on all applicable SPS TPF data or user-defined defaults. Table 24 contains the field names and descriptions.
LTPP_CODES - This table, imported from the LTPP LTAS database, contains numeric codes and names for all the States and Provinces in the United States and Canada. Table 25 contains the field names and descriptions.
PLUG_LEF_FOR_ESAL - This table contains load equivalency factors by axle type and is used for Percentage of Total Load (ESAL) computations. Table 26 contains the field names and descriptions.
PLUG_W_FACTORS_FOR_RPPIF - This table contains W-factors by axle type and is used for Percentage of Total Load (RPPIF) computations. Table 27 contains the field names and descriptions.
SITE_SPECIFIC_AxlesPerTruck - This table contains APCs for each site. Table 28 contains the field names and descriptions.
SITE_SPECIFIC_NALS - This table contains representative annual NALS for each SPS TPF or user-supplied site. Table 29 contains the field names and descriptions.
SITE_SPECIFIC_NVCD - This table contains the normalized vehicle class distribution for the most recent year for all SPS and GPS sites or user-supplied sites. Table 30 contains the field names and descriptions.
USER_DEFINED_NALS - This table contains user-defined NALS based on the computation performed under Action 3 of the LTPP PLUG software (multiple sites selection and computation of NALS). Table 31 contains the field names and descriptions.
XMLGen_AxleLoadDistribution, XMLGen_AxleLoadMain_Template, and XMLGen_DEFAULT_NALS_By_Loading_Cluster - These tables are used internally by the LTPP PLUG software to generate DARWin-ME *.xml files. Table 32 through table 34 contain the field names and descriptions.
