CUBE.6 Program Basics

• This course is designed for those interested in learning more about Cube Base’s graphical user environment and integrated geographic information system (GIS).

- We will use:

• Cube Base:

• GIS Window

• Data Manager

• Application Manager

• Scenario Manager

- Attendees will learn:

• How to add, link, and sequence programs to create reusable applications

• How to create nested application groups and define process flow logic controls

• How to create model catalogs and set up scenario-specific application parameters

• Basic syntax and structure of Cube Voyager script commands

• Best practices and techniques for editing Cube Voyager scripts

• How to automate common network, matrix, and other data manipulation tasks

• How to build a standard model in Cube Voyager, with specific focus to the modules NETWORK, MATRIX, HIGHWAY, FRATAR

Cube consists of:

- Cube Base

• Data Manager: organize data

• Application Manager: flow-chart style tool for building model systems

• Scenario Manager: tool for applying the model to multiple scenarios

• Cube GIS: editing of all data in text, tabular and graphical form

- Functional Libraries or Modules:

• VOYAGER (Passenger Forecasting)

• AVENUE (Dynamic and Mesoscopic Simulation)

• DYNASIM (Dynamic and Microscopic Simulation)

• ANALYST (Matrix Estimation)

• CARGO (Freight Forecasting)

• LAND (Land Use)

The typical model development workflow

- Gather and code data

• Transportation networks: roadway centerlines, intersection definitions, public transit routes

• Define TAZ boundaries and summarize demographic and economic factors (households and employment) by zone

- Define model functions

• Obtain travel behavior inventory or survey data

• Specify, estimate and calibrate mathematical relationships using statistical tools & methods

- Link data and processes with interface

• Lay out application groups and programs

• Sequence steps and link common data files

• Create catalog; run, review, revise as needed
