Showing Transit Assignment Results
The Highway Reporter displays the flows of passengers
or vehicular traffic in the line network. You can draw
the aggregated flow per link of all lines for passenger orvehicular traffic, or the flow per link of a specific line forpassenger traffic.

The System for Traffic Demand Analysis (STRADA)
packages a number of programs for transport demand
forecast that are operated on the Windows.
Japan International Cooperation Agency (JICA) initiatedthe STRADA program development to provide a common
tool of transport planning, and to build up common
database thereof, for its technical assistance program in
the transport sector for developing countries. The efforts
began in 1993 under the leadership of the then Prof. Hideo
Nakamura at Tokyo University with participation of someexperts in the relevant fields, officials from the Ministry of
National Land and Transport (the then Ministries ofConstruction and Transport) and private-sector
consultants. Since 1997, the STRADA program package
has been available for the interested general public as well
as being used widely in the JICA-financed overseas
projects. Continual upgrading efforts since now provideyou with Version 4 of enhanced capability, with newly
added features and programs.

Maintenance of a transportation facility brings big
influence to social economy activity of an area. The
Evaluator calculates evaluation indices, such indicesas the time cost, running cost, loss by accidents andan environmental loss.

Specification of Costing Unit
Showing Boarding and Alighting Passengers

The default file contains the basic units used in Japan.
You cannot alter the formulas themselves. However, theformulas are linear to the traffic volume and thus
applicable to countries other than Japan by adjusting
the basic units. The set-up basic unit can be saved.

Calculation of Evaluation IndicesＩｎｔｅｒｓｅｃｔｉｏｎ Ａｎａｌｙｚｅｒ
Intersection plan, intersection design, and intersection
employment are very important.

The Evaluator reads an assignment results file andcalculates, by using the user-specified basic units. The
list of the calculated evaluation indices can be saved at
the file of CSV format.

Input Data
The Intersection Analyzer calculates the saturation rate
and the queue length at an intersection when you set up
the traffic and road conditions. The Program draws thegraphic diagram from the results of analysis and cansave the results in the formats readable by Excel.

Unit and Adjustments
The Intersection Analyzer applies the default
parameters and adjustment factors based on thestandard practices in Japan. You can tailor the defaults
to suit the transport conditions of your study area andsave them in a new parameter file.

Multi-lingual Operation

In addition to the standard STRADA record formats, Version
4 supports the CSV format for a greater number of file types
than the prior versions. Accordingly, many data files can now
be edited by some commercial spreadsheet application or GISapplication. The results of forecast and assignment can beoutput in the CSV format or in the metafile to ensure easierconvertibility with commercial software applications.

Improved Convertibility of GIS data
Version 4 has substantially upgraded the ease of conversion
between the GIS and the STRADA data format.

Faster route search
A route search high-speed logicI is used in the assignment
model. Route search time is now less than 1/3 of the Ver.3
by performing parallel processing on a PC there are two ormore CPU.

Data Edit Functions

Ｄｉｓａｇｇｒｅｇａｔｅ Ｍｏｄｅｌ
The Disaggregate Model analyzes each person’s
choice directly. The Disaggregate Model is mainly
used for modal split model.

Model Building
The Disaggregate Model performs model building andaggregation thereof either by the multinomial logit(MNL) or the two-level nested logit (NL) modelstructure. If you choose the NL type model building,
you can freely define a tree structure. In order toobtain the maximum likelihood for the undeterminedparameters, the Quasi-Newton Method based on theBFCS theorem is applied. The parameter can be applieda statistical test.
The DisaggregateModel can do themodel building on trip
generation/attraction
and trip distribution
as well, but it
performs aggregation
only on its modal
split models.

Process of the unique data structure on traffic demand
forecast, and adjustment calculation like the Fratar
technique can be easily performed. The index by a zone
can calculate the data which became a matrix format.
According to division/integrated parameter of a zone,division and integration of OD matrix or zonal indicescan be done.

View Edit Functions
Zone coordinates file and OD matrix file are read, and it
can display, being able to use arbitrary OD traffic as thedesired line diagram. Zone coordinates file and theattributes value classified by zone are read, andon a zone figure, it can graph-display. By a figure
ornamentation function, you can change a setup. Theline figure of
the displayed
graph and thedesiredline
diagram by themetafile canbe outputted.

Characteristic Functions

Ｎｅｔｗｏｒｋ Ｅｄｉｔｏｒ
The network editor, you can build and edit even alarge-scale road network.
Characteristic Functions
It supports not only the standard STRADA format, butalso CSV file format. The function of the continuous
operation of package correction convenient forcorrection of link information and correction, deletion,
and an addition can perform editing work easily.
Moreover, since network editor is uniting withassignment parameter editor, data required for
assignment can be created simultaneously.
The shortest path search is possible without using theassignment model. In addition to the calculation of travel
time or distance between any two points, thecalculation of the impedance between zones is possible.

Showing Link Results
The Highway Reporter shows link assignment results invarious graphic forms. The information outputted to theassignment result file can be chosen and displayed. You
can specify the display direction of traffic (Both orSeparate). Moreover, you can set up the display color of alink. The metafile output of a display screen is possible.

ＧＩＳ Ｃｏｎｖｅｒｔｅｒ
The GIS Converter performs the file conversion
between the data prepared by two GIS commercial
applications, viz., ArcGIS and MapInfo, and the data
used by the STRADA program modules.

Characteristic Functions
When User Equilibrium Assignment is carried out basedon the existing OD matrix, this program rectifies OD
matrix so that observation traffic may be obtained. As
the method of adjustment, the Route Mean square Error
Minimizing Model and the Entropy Maximizing Model areapplicable. The OD
Calibrator handles
only one mode. But
it can apply also
to the conventional
screen compensationand distortion ofOD matrix can beremoved.

Large-scale Network

Transit Line Edit Functions
Public traffic line data is required for transit assignment.
The Network Editor builds/edits the public
transportation line. The line which passes a specific link
and a specific node is extracted, and there is a function
which carries out a data check visually by displaying line
data information on a screen.

With the incremental assignment program, you can choose
from the alternatives of assignment, such as theAll-or-nothing method, the diversion-rate, and thevariations of incremental assignment with capacity
restraint.

User Equilibrium Assignment
The STRADA has two models, user equilibrium
assignment and stochastic user equilibrium assignment.
The Stochastic User Equilibrium Assignment is thelogit-type model for multi-modal link flow assignment. It
offers three alternative algorithms: the successive
average and the partial linear approximation methods byDial loading, and the simplicial decomposition method.

Notes: Please use a BPR type in Equilibrium Assignment.

The Highway Reporter retrieves the link informationfrom the assignment results and converts them intovisual presentation.

Desired LineOD matrix is made based on the results of aperson’s trip survey or OD traffic survey. However,these investigations cost great time and expense. If
you have an existing OD matrix, you can adjust it tobe consistent with the results of a traffic countsurvey by the OD Calibrator.

Showing Link Assignment Results separated by direction

Displaying Some Assignment Results
The Highway Reporter can display the traffic volume
per direction of flow at a user-selected node(intersection). You can set up display conditions.
Moreover, the traffic of an object crossing can bechecked by tabular form. It can output to the file ofCSV file format.
The Highway Reporter can display the routeinformation for zone pairs and for the user-specified
links. You can set up display conditions andcandidates freely. When you have opened a routeinformation file with user specification of links, theHighway Reporter can output an OD matrix between
the link pairs.
