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 the Network.
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 Tree– Select Link Origins– Select Link Destinations– Select Link O/D Ratio
Select Link Tree
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
Difference– Turning Movement
Comparison– STEAM
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”
