Display keyed network attributes using
bandwidth and color
3
New in Cube BaseDynamic Intersection Displays

period
4
New in Cube Baseemail model status
When running from Voyager.exe, allows the user to
ask for an email to be sent when model run is
completed
5
New in Cube Basetransit access geoprocessing
Calculate and save zone-level access to transit
stops
6
New in Cube Baseexternal program wizard
Enables users to more easily add external
programs to the Cube Base program menu
7
New in Cube Basemultiple model appliers
Allows to set available keys (parameters, file
options, etc) for several model user types along
with separate passwords
8
New in Cube Basemerge catalogs
Merge Applications, Keys and Scenarios from other
Catalogs
9
New in Cube Basedirect read of binary networks
and matrices in Cube Reports extension
Direct reading of binary files saves steps to
export to DBF
10
New in Cube VoyagerPT select link

• Get selected link/node trip tables
• Link Specific
• Node Specific
• Mode specific
• Line specific
• Operator Specific
• Any combination of the above
• Useful for evaluating project demand
• Can identify/output percent or probability of
  trips IJ using the selection

11
New in Cube VoyagerPT mustusemode and
bestpathonly

• Added for enhanced FTA New/Small Starts Review
  compatibility
• BESTPATHONLY
• Selects only path with least cost from enumerated
  routes
• Can be any mode including all walk (with
  appropriate connectors generated)
• MUSTUSEMODE
• Selects mode combinations from enumerated routes
• Can use a single mode, group of single modes or
  mode combination to evaluate (e.g. rail only,
  walk to bus, walk to local bus to rail, etc).
• Alternative methods available for headway
  calculation
• New controls for route enumeration and evaluation
  processes

New Extension to Cube Voyager Cube Avenue

• Mesoscopic assignment (dynamic traffic
  assignment)
• - representing vehicles as discrete packets or
  individual vehicles
• - assigning a specific time of departure from the
  origin point in the network to each packet or
  vehicle
• - routing the vehicles along multiple paths in
  response to dynamic traffic conditions
• - representing queues and bottlenecks including
  blocking back or the formation of queues on a
  roadway segment or at an intersection which spill
  back up-stream to block roadway segments which
  feed into the roadway segments
• 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

14
New Extension for Cube Base Cube Cluster

• Brings very large time reductions in model runs
• Provides 2 types of savings
• Multi example take a three time period run and
  run the mode choice models on three PCs
  simultaneously
• Intra example run one mode choice model over
  multiple PCs.
• Time savings can be substantial
• Take a 10 hour run model and put across 10 pcs.
  Processing time reduced to 1 hour and 10 minutes

• Architecture 1 desktop license plus multiple,
  low cost node licenses

Some new graphics under development for Cube 4.2?

• Packet animator for Cube Avenue
• A quick peek

18
Making scripting easier in Cube 4.2

• Templates
• Exist today
• Currently building a comprehensive library
• More context-driven

19
Cube 5.0 Cube Land

• Innovation in land use pricingvia
  auction/bidding theory
• Econometric-based model
• Integrates Cube Voyagers transport accessibility
  measures and ESRIs spatial mapping/analysis
  capabilities
• Works directly with property tax appraiser
  parcel-level data for a bottom-up, agent-based
  approach to forecasting
• Forecasts land rent/prices to better evaluate
  development pressures

20
Cube 5.0 Embedded ArcGIS

• Cube 5 embeds GIS functions
• Based on ArcObjects from ArcGIS Engine
• Provides enhanced GIS capabilities to Cube users
  at no additional cost
• Can take advantage of ArcGIS license and
  extensions already on your computer
• Stores data in geodatabase format
• 5.0- Personal geodatabase (MDB)
• 5.1- Enterprise geodatabase
• Provides geoprocessing functions based on ESRI
  Technology

21
Cube Web - Accessing the Model via the Internet

• Upload scenario data from remote site (locality)
  to central server
• Log in and access model via internet
• Eliminates the need to have local versions of the
  model
• Vastly improves management and access to the
  model system across a region and to consultants

Cube Web Reminderhow the desktop works
23
Cube Web live demonstration

• Part 1 run a scenario
• start my browser
• go to a URL
• logon as a user
• navigate to my workspace (my data) and get a list
  of what I have available as inputs for my runs
• create a new scenario linking in a selection of
  my inputs network, zonal data
• launch the run
• check status
• get an email when it is done download the loaded
  network and open in Cube

24
Cube Web live demonstration

• Part 2 upload new data, create a new scenario,
  run it and get email
• locally, edit a network, save file
• start browser and upload the network to my space
• create a new scenario
• use that new network
• launch scenario, run it, get notification,
  download results and view
