II. Instructions for Using the Travel Demand Models in
TransCAD: Ordered-Response Probit Model
for Trip Generation
To install the trip generation add-in script:
1. Open TransCAD; 2. Go to TransCAD menu "Tools", click "Add-ins"; 3. In "Add-ins" window, click "Setup"; 4. In "Setup Add-ins" window, click "Add". Type "Ordered-response Model
Forecasting" in the Description box, type "ORP" as Name (case sensitive), and "e:\Trip Generation\UI_ORP\orp" in the UI Database box and click "OK".
To run the ordered-response model for trip production model:
1. Open a map (e:\Trip Generation\tsz90\tsz90.map) that contains zonal structure
information for the study area;
2. Go to menu "tools" and choose "add-ins". In the "add-ins" window (as shown in
Figure 11-1), choose "Ordered-response Model Forecasting", and click "OK".
The implementation procedure is now activated.

3. After the add-in procedure is activated, an open-file window (as shown in Figure
11-2) will pop up. First, select a household demographic distribution table
(e: \Trip Generation\hbw\householdworkers .dbf) and click "open"; then, select a
model coefficient table (e:\Trip Generation\hbw\hbw_l.dbf) and click "open";

4. An input dialogue box will then ask users to provide information on the number
of independent variables in the model coefficient file, the maximum number of
trips, and the trip purpose. The user can either choose inputs from pull-down
menu or type inputs directly. In this example, the number of independent
variables is 2; the maximum number of trips is 6; and the trip purpose is HBW
(as shown in Figure II-3).

Figure 11-3. Input dialog box
5. With all the required inputs TransCAD will calculate the trip productions for
different household groups. The user can output the household trip productions
to an existing file or save it as a new file .
6. Once the calculation is done, the user has a choice of continuing to implement
another trip purpose. If the user selects "no", the ORP module will aggregate
trip productions for each TAP and save the TAP level trip productions into a file.
The TAP level trip production results are also connected to the map so that the
trip production information is provided in the "info" window by clicking on any
TAP.
The trip productions for home-based non-work and non-home-based trips are saved in
file "tap _production.dbf'.
III. Instructions for Using the Disaggregate Attraction End
Choice (DAEC) Model for Trip Distribution in TransCAD **
1. Input Files required
A prior implementation of the trip production phase is necessary to use the DAEC
model. The inputs required for the DAEC macro are summarized in Table III-1. The next
section discusses the requirements for the format and contents of the input files.

2. Input File Description
The input files listed in Table III-1 are pre-requisites for the DAEC program. It is
necessary that the file formats and contents are the same as indicated in Table III-1. This
section elaborates on the requirements for file structure and contents to use the DAEC
macro.
2.1. Trip Production File
The DAEC macro allows the user to compute trip interchanges from zonal trip
productions using traveler socio demographic characteristics and attraction zone
characteristics. It is, therefore, necessary to implement the trip production phase before
the DAEC macro is used. The trip production file must provide a zone wise trip
production count. The zones are identified by their TAP numbers and the productions
* The current version of the DAEC Macro does not function for very large data sets of the order of900 zones. It is advisable to use the macro for smaller data sets of the order of 100 zones.
from these zones by a field "PROD". In essence, the trip production file must necessarily
have two columns - the first column representing the TAP and the second named PROD
showing the corresponding trips produced. The trip production file structure is shown in
Figure III-1. This file structure allows the user to compute trip interchanges for each trip
purpose separately.

2.2. Impedance Matrix File
An individual's choice of attraction end for a trip 1s dependent upon the
impedance to travel between the production and attraction zones. In this project, a
composite impedance matrix has been used for trip distribution. The composite
impedance terms capture the combined effect of travel time (both in-vehicle and out-of
vehicle) and cost for each available mode on the utility of choosing a particular attraction
zone. The computation of these values has already been discussed in the previous
sections. The composite impedance matrix is a square matrix with a size equal to the
number of zones in the planning region. The row labels are the production zone ids and
the column labels are the attraction zone ids. The number of rows and columns in the
impedance matrix should be the same as the number of observations in the trip
production file. The matrix file structure and contents are shown in Figure III-2.

2.3. Socio Demographic Coefficients
People with different socio demographic characteristics have different perceptions
of disutility to travel. For this reason, the composite impedance matrix is not the same for
all socio demographic groups. The DAEC model takes this into account through an
interaction term between the socio demographic groups and the composite impedance.
The DAEC macro, therefore, seeks a socio demographic coefficient fil e. The number of
socio demographic groups varies from one trip purpose to the other. The number of
records in the socio demographic coefficient file is the same as the number of socio
demographic groups. The socio demographic groups are represented by the field
SDGROUPS and the corresponding interaction coefficients by the field COEFF. The file
structure is shown in Figure III-3 .

2.4. Land Use File
The number of trips attracted to a zone also depends on the attraction zone
characteristics. The zonal size measures are proxy measures for the number of elemental
destinations within a zone. In the current study, total zonal employment has been
introduced as a size measure for the HBW purpose and zonal retail and service
employment is used for HBNW and NHB purposes. In addition zonal office, industrial
and institute areas have also been included in the model. The DAEC macro, therefore,
also seeks a land use file to compute the trip interchanges between the zones. The land
use file must contain information on the zonal retail, service, industrial, institute areas
and the total zonal employment. The land use file structure is shown in Figure III-4.

3.2 The Trip Interchange Matrix Output
The output from the DAEC macro is a matrix file showing the trip interchanges
from one zone to the other. The matrix obtained from the trip distribution stage shows the
trips produced from a zone and attracted to every other zone. The program informs the
user about the directory and file path of the trip matrix using a message dialog box. The
trip matrix can then be converted to an 0-D Matrix using the "PA to OD" function
provided by TransCAD. Figure III-11 shows a sample trip matrix output file. .. ,,\.:'Ill :•••' . .,, ·A•

Instructions for Using the Trip Interchanges Workspace to Obtain Trip
Information
1. Opening the Workspace
Open the TransCAD window and go to the File -> Open Work Space option as
shown in the picture below.
Figure 111-12. Opening a TransCAD workspace.
This opens a File Open Dialog box as above. Follow the path shown below:
Trip Distribution-> Output-> Triplnterchanges.wrk
This will lead to the screen shown in Figure III-I 2.

Figure 111-13. The Trip Interchange Workspace.
The screen opens with a vertical tool bar as shown. Please note that the
desire lines shown are just an example. You can obtain information on trip interchanges
between any two zones by using the Tools ->Geographic Analysis ->Desire Lines and
then suitably choosing the required trip interchange matrix.
The layers in the map are displayed on the top left hand corner of the
window. Select the required layer to display it. For instance, to view the trips made by
driving alone in the AM peak, select the corresponding layer from the menu. To display
the trip information, select the Q button from the tool bar. This attaches the "i" to the
mouse pointer. Trip interchanges by mode and departure time can now be displayed by
clicking on each of the desire lines displayed. The process may be repeated for any of the
layers in the map.
IV. Instructions for Using the Mode Choice Models
The mode choice estimation input and output files are saved in "e:\Mode Choice" by trip
purpose. The HBW trip files are in "e:\Mode Choice\HBW", the HBNW trip files are in
"e:\Mode Choice\HBNW", and the NHB trip files are in "e:\Mode Choice\NHB".
1. Input Files
a. Model parameter file: hbw.bin (for HBW), hbnw.bin (for HBNW),
nhb.bin (for NHB)
b. LOS file: peak.mtx (for peak hours), NHB(HBNW)_LOS.mtx (for off
peak hours)
2. Output Files
a. For HBW trips: HBWAMOD.MTX (for AM peak hour 7-8 AM),
HBWOD.MTX (for 24-hour volume), and HBWPMOD.MTX (for PM
peak hour 5-6 PM)
b. For HBNW trips: HBNWAMOD.MTX (for AM peak hour 7-8 AM),
HBNWOD.MTX (for 24-hour volume), and HBNWPMOD.MTX (for PM
peak hour 5-6 PM)
c. For NHB trips: NHBAMOD.MTX (for AM peak hour 7-8 AM),
NHBOD.MTX (for 24-hour volume), and NHBPMOD.MTX (for PM
peak hour 5-6 PM)
