This section documents the output files that are used on a regular basis when reviewing model results. It includes attributes added to the highway networks, travel time skims, CT-RAMP output files, and trip tables.
The list of highway networks created throughout the model process is provided in Table 7-1. Most of the networks are intermediate files which are referenced in later model steps. The attributes that are added during a model run are provided in Table 7-2. Note that not all of the attributes can be found in all the networks listed. For example, the volumes by vehicle type will only be located in the loaded highway networks.

During model application, a number of highway and transit skim files are created by time period which provide information regarding zone to zone travel times, distances, etc. for both highway and transit travel. A list of the most important files is provided in Table 7-3. There are other matrices created for different applications in the model; however, all of them are built from the files listed. Table 7-4 through Table 7-7 shows the format of the highway and transit skims. The distance and IVT tables include intra-zonal distance and time.
The format of the transit skim tables is different because the model now uses PT rather than TRNBUILD. Previously, all transit travel times were in hundreds (i.e. 1 minute was expressed as 100). With the switch to PT, the travel times are in real units. The transit skims are stratified differently in this model. Before the transit skims were stratified by local service only and combined local and premium service. In the new version, the all transit (ALLTRN) skims represents combined local bus and premium service while premium (PREMIUM) skims represents premium service only.

The air passenger model has also been converted to Cube script from FORTRAN. However, the file formats are the same as in previous versions. The air passenger model generates a vehicle and transit trip table. The vehicle trip table is called VEHOUT{year}.MTT and the format is provided in Table 7-8. The transit trip table is called TRNOUT{year}.MTT with the format provided in Table 7-9.

Portions of the external model were previously applied in FORTRAN executables. In the new model, all components of the externals are handled within the Cube script. The internal-external station passenger car productions are created in a text file called IEPRD{year}.PRN with the format shown in Table 7-10. The internal-external passenger car attractions are stored in a text file called IEPA_B{year}_ATT.NEW with the format shown in Table 7-11.

After trip distribution, the internal-external passenger car trips are stored in two trip tables:
The basic format of the two trip tables is the same although the table names are slightly different. The formats are provided in Table 7-12. The external-external passenger car output is a trip table called EEPC20{year}.VTT shown in Table 7-13.

The internal-external trip ends for commercial vehicle, medium truck, and heavy trucks are created and stored in the text file CMHEXT.PRN. The format of this file is shown in Table 7-14. The external model also creates the initial external-external vehicle tables which are later modified in the commercial vehicle and truck model. The name of the initial file is called CMHEE.TRP and the format is shown in Table 7-15.

The file formats of the commercial vehicle and truck model have not changed in the newer model version. The program produces an initial internal-internal and internal-external file called CMH.TRP. Note that this file is not used for assignment. The file format is provided in Table 7-16. The final tables used for the assignment are as follows the format provided in Table 7-17.
