8.2.5. MBINV: Mobile-source activity and emissions

8.2.5.1. IDA Format
8.2.5.2. EMS-95 Formats
8.2.5.3. ORL Format (Toxics)

The MBINV file is the input mobile-source inventory data file. Two IDA formats are available: one for activity data and one for emissions data. Note that although the IDA formats support the link ID field, SMOKE cannot read the IDA link definitions file, which contains the coordinates for the links. In order to use link data with SMOKE, the EMS-95 format must be used. SMOKE also supports the ORL format for reading on-road mobile toxics data.

8.2.5.1. IDA Format

The two IDA formats for mobile-source inventories use the header described in Section 8.2.1.4, “Header records”. Sample header records for activity data are shown below:

#IDA
#TYPE     Motor Vehicle Activity Inventory
#COUNTRY  US
#YEAR     1996
#DESC     1996 NET inventory, version 3.1
#DATA     SPEED VMT
#UNITS    "miles/hr" "10E6 miles/yr"

Sample header records for emissions data:

#IDA
#TYPE     Motor Vehicle Emission Inventory
#COUNTRY  US
#YEAR     1996
#DESC     1996 NET inventory, version 3.1
#DATA     VOC NOX CO SO2 PM10 PM2_5 NH3
8.2.5.1.1. IDA Activity Data Format

The IDA activity data format is list-directed and shown in Table 8.36, “IDA Activity Data Format for MBINV”.

8.2.5.1.2. IDA Emissions Data Format

The IDA emissions data format is column-specific and shown in Table 8.37, “IDA Emissions Data Format for MBINV”.

76-85 AVD(3) Real Average-day data for the third field (short tons/average day)
... DATA(n) Real Data for the final field (short tons/yr)
... AVD(n) Real Average-day data for the final field (short tons/average day)

8.2.5.2. EMS-95 Formats

For EMS-95 inputs, the MBINV file can either be a list file, to read in EMS-95 link and non-link data, or a single modified EMS-95 format that is list-directed. When using a list format, the MBINV file must contain at least one INVYEAR packet (see Section 8.2.1.5, “INVYEAR packet for EMS-95 format”). The individual data files that are referenced by the MBINV list file may also contain the following header fields: #COUNTRY, #YEAR, and/or #DATA, as described in Section 8.2.1.4, “Header records”. The default country is 0 and the default year is set by the INVYEAR packet. The #DATA header must appear, even if the only data in the file are VMT data. The #UNITS header must NOT appear.
