Cube Voyager provides a comprehensive library
of functions for the modeling and analysis of passenger transport
systems: roadways, public transit, pedestrians and
bicycles.
Voyager functions:
- Networks : 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, circles,
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, Burrell. Capacity restraint: intersection,
link or both using standard processes or user supplied curves or equations.
- Assignment: iterative and incremental using equilibrium
adjustment.
- Junction-based assignment: 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 controlled
matrices of times, costs,
distances by mode and component. Large number of reports and
tabulations of public transport data and results.
Voyager provides a major improvement to public transit assignment
as compared with other packages. The discrete route multi-path
process estimates, full, alternative paths between each origin
and destination along with the individual elements of public
transit costs (access times, wait times, transfer times, ...).
TRIPS are assigned across paths using a multinomial logit
approach.
- Travel Demand
Cube Voyager Demand processes zonal data and matrices according
to user specified expressions. Zonal 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 Demand can apply it.
