PT User Benefits Analysis Features
New Features of Cube Voyager

• BESTPATHONLY
• Selects only path with least cost from enumerated
  routes
• Can be any mode
• MUSTUSEMODE
• Selects mode combinations from enumerated routes
• Can use a single mode, group of single modes or
  mode combination to evaluate
• Alternative methods available for headway
  calculation
• New controls for route enumeration and evaluation
  processes

21
Extension to Cube Voyager -- Cube Avenue
New Features of Cube Voyager

• Mesoscopic assignment (dynamic traffic
  assignment)
• representing vehicles as discrete packets or
  individual vehicles
• assigning a specific time of departure
• routing the vehicles along multiple paths in
  response to dynamic traffic conditions
• representing queues and bottlenecks including
  blocking back
• providing the ability to represent intersection
  geometrics and traffic control systems in detail.
• Region-wide, corridor-level
• Evacuation modeling, greater analysis of
  geometrics, traffic control and ITS strategies

22
Extension for Cube Voyager -- Cube Cluster
New Features of Cube Voyager

• Brings very large time reductions in model runs
• Provides 2 types of savings
• Multi take a three time period run and run the
  mode choice models on three PCs simultaneously
• Intra run one mode choice model over multiple
  PCs.
• Time savings can be substantial
• Take a 10 hour run model and put across 10 pcs.
  Reduced to 1 hour and 10 minutes
• Architecture 1 desktop license plus multiple,
  low cost node licenses

Key Technologies in the Labs
25
New traffic assignment methods

• Most packages use link-based Frank-Wolf
• requires less memory and relatively easy to
  implement
• but may experience low convergence speed at the
  vicinity of the equilibrium solution.
• New methods
• Conjugate and Bi-Conjugate Frank Wolf
  Path-based
• more complex and need much more memory
• but converges faster to higher accuracy levels.
• Gradient Projection Algorithm
• Origin Based should be more accurate
• Higher speeds than path based methods.
• Limitation of not being able to efficiently
  handle networks with turn penalties/prohibitions.
• .

New traffic assignment methods
27
New traffic assignment methods

• We are actively working with our customers,
  David Boyce, and other researchers to explore and
  test the OBA, Algorithm B, and TAPAS
  methodologies.
• Stochastic Methods although a popular
  alternative methodology in uncongested networks
  for customers using TRIPS and Tranplan, a new
  stochastic methodology is being built for Voyager
  5.1.
• Route Choice As an advance from the basic
  stochastic methods, we are building discrete
  route choice algorithms giving users the freedom
  of using any variables in their custom utility
  functions.
