Transportation Modeling History
• 1950’s
– Traditional Four Step Modeling Process
• 1960’s and 1970’s
– Main Frame Computers
• 1980’s
– Personal Computers using Tranplan
• 1990’s
– Geographic Information Systems (GIS)
Tranplan and ArcView
• Tranplan
– Familiarity with Program.
– State-wide License in Iowa.
– Proven Performance.
• ArcView
– Selected as Main Focus of Project Team
– Premier GIS Package on Market Today
– Required of MPO’s by TAZ-UP.
Previous Interfaces
• FORTRAN Based DOS Inputs
– Rigid Requirements
– No Help Options
– Input Errors “Crashed” Program
Current Interface
• Visual Basic Based Windows Inputs
– User-Friendly Forms
– Tool-Tip Help Screens
– Automatic Error Sensing and Reporting
Building a Network
• Create a Tranplan Network
– Nodes, Links Coordinates
• Create a New Network
– Trace Network over Aerials in ArcView
• Netcard Splitter
– Use Tranplan Binary File
• Edit Network
ArcView Operating The Interface
• Pull-Down Menus Added
Creating A Tranplan Network
• Tranplan Network
– Use Formatted Nodes
and Links Files to
Create an ArcView
Network.
Create A New Network
• New Network
– Trace an aerial in
ArcView to Create
Formatted Nodes
and Links Files.
Tranplan Network In ArcView
Tranplan Control Files
• Automated Tranplan
Control File Creation.
– Standard Network
Builder
– Runs the Build
Highway Network
Module
Tranplan Control Files
• Default Module
Builder
– Optional Control File
to Complete Modeling
Process.
– Instructs Tranplan to
Create All Required
Files for Analysis
Tools.
• User-Created Control
File
Adding Tranplan Output
• Tranplan is Executed
by the Interface.
• Netcard is Opened.
• Output is Added to
Network.
the
Tranplan Output in ArcView
• Loaded Link Volumes and Centroid Values
Calibration And Analysis Tools
• Calibration Plot
– Ratio between Loaded and Counted Volumes
– Colored According to Ratio
– Sized by Loaded Volume
Calibration And Analysis Tools
• Screen/Cut/Cordon Line
Calibration And Analysis Tools
• Select Link Analysis

Select Link O/D Ratio
Calibration And Analysis Tools
• Shortest Path Finder
– User Selects Two Centroids in ArcView
Calibration And Analysis Tools
• Origin to Destination Desire Line
– User Selects Two Centroids in ArcView
– Loaded Volume Between Points is Displayed.
Calibration And Analysis Tools
• Turning Movement Display
– User Selects up to Ten Nodes.
Continuing Research
• Scenario Analysis
– Buffer Volume
– Turning
Movement
Comparison
– STEAM
Difference
Continuing Research
• Subarea Analysis using CORSIM
• Statistical Analysis of Tranplan output
Conclusions
• Advantages
– Visualize Data
– Novice Tranplan Users
– Calibration and
Analysis Tools Built-in
– Debugging Data in
GIS Environment
• Disadvantages
– Requires More
Software Packages
– Less Hands-On with
Data and Network
– “Black Box”
