SERPM65 – Model Flow
1. Setup controls and file names
2. External – EE by period
3. Trip Gen – LSGEN by auto
ownership and TOD
4. Highway – Includes speed and
capacity calculators
5. Distribution – Includes
equilibration (FEEDBACK) of
peak period highway speeds
6. Transit Nets – PT  Trnbuild
and connectors, paths, skims
and fares
7. Mode Choice
8. Transit Assignment by access
path and TOD
9. Highway Trip Tables –
Combines trip tables for
assignment – 24H & TOD
10. Highway Assignment – 24
Hour & by TOD (use most
computer time)
11. Highway Evaluation – HEVAL
and RMSE by TOD and
county & User selected
subarea

A Few Differences on Model Processes
 Full Model: Trips for HH with autos distributed using highway skims, while 0auto HH use transit skims.
 HO/Subarea Model: All HH Trips are distributed using highway skims.
 Full Model: Separate motorized and mode choice analysis of Zero, one and
two-or-more HH autos for the HB (HBW & HBNW) trips.
 HO/Subarea Model: No separate motorized and mode choice analysis of
Zero, one and two-or-more HH autos for the HB (HBW & HBNW) trips.
 Full/HO Model: Trip matrices are at individual TAZ levels.
 Subarea Model: Trip matrices are aggregated at district levels outside
focused region.
 Less/Sparse centroid connectors outside focused region of the Subarea
network used in assignment.
 HO/Subarea model uses same default transit splits for each IJ pairs.

New Input Files –
Users need to check/update (if necessary)
DLEVEL_XX.DBF (a value of “0” or “1” means
that aggregation “is not” or “is” at district level.
XX = AL, xx, PB, BO, MD
File location: {DATADIR}
SADISTS_XX.DBF (specify subarea
district/CenterTAZ)
XX = AL, xx, PB, BO, MD
File location: {DATADIR}

Other New Input Files
PROFILE-PKHO.MAS (same as PROFILE.MAS)
File location: {DATADIR} folder
PROFILE-OPHO.MAS
File location: {DATADIR} folder
Only difference is in &DEFMS (Default Regional Mode Splits) parameters. The
peak and off-peak values of HBW, HBO and NHB are swapped in
columns (1-3 and 4-6)

NLOGIT-PKHO.SYN (same as NLOGIT.SYN)
File location: {DATADIR}\transit folder

NLOGIT-OPHO.SYN
File location: {DATADIR}\transit folder
The peak and off-peak parameters of HBW, HBO and NHB are swapped in
columns (1-3 and 4-6)
