Cube Voyager - Modeling Functions

Network

Create detailed representations of roadway segments, intersections and ramps. This module creates a comprehensive roadway database for use in estimating point-to-point paths and associated travel times, costs, and distances.  A key element in Cube Voyager is the ability to represent signaled and non-signaled controlled intersections, roundabouts, and ramps as part of the pathfinding and assignment process.  

This module serves as a general calculator providing the ability to compare and contrast highway and public transit networks and their variables.

Highways

Used to estimate zone to zone paths and matrices of impedances for use in analysis and in demand models.

• Paths can be built using a variety of methodologies: all-or-nothing, all-shortest paths, Burell and stochastic.
• Capacity restraint: intersection, link or simultaneous intersection/link using standard processes or user supplied curves or equations.

Assignment

Iterative and incremental using equilibrium adjustment.  The latest in methods for tight convergence and quick run-times.  Cube Voyager includes methods for performing intersection constrained assignments. This process provides the best estimate of travel flows, delays and queues in urban locations

Public Transit

Provides advanced functionality for the study of public transit systems. Cube Voyager provides the capacity to study even the largest and most complex public transport systems. Unlimited lines, unlimited links and unlimited modes. Public transit services are coded as running in mixed traffic or on dedicated facilities. Automated processes for creating walk, automobile and transfer links between services. Ability to represent infrequent and time coordination. Point to point paths are found using a variety of techniques: all-or-nothing, stochastic multi-path, or discrete route multi-path.  Users may represent services levels using either headways or public transit timetables. Cube Voyager provides methods to represent highly complex fare structures and for modeling public transit capacity restraint. Outputs user specified matrices of times, costs, distances by mode and component. Large number of reports and tabulations of public transport data and results.

Travel Demand 

Cube Voyager processes zonal data, record data,  and matrices according to user specified expressions. Zonal data, record data, and matrices are input, and matrices and reports are output. Various file formats for both input and output are supported. There are no default processes. The powerful scripting language combined with user-friendly wizards, allows for the application of all types of commonly used demand processes (multinomial and hierarchical choice models, cross classification and regression models, gravity models, matrix frataring). New functionality is provided for applying activity-based processes using travel tours. If you have a complex demand process, we are almost certain that Cube Voyager can apply it.
