New in Cube Base:Dynamic Bandwidth, Colors..

Display ‘keyed’ network attributes using bandwidth and color

3


New in Cube Base:Dynamic Intersection Displays

Display queue, capacity, delay, volume by time period

4


New in Cube Base:email 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 Base:transit access geoprocessing

Calculate and save zone-level access to transit stops

6


New in Cube Base:external program wizard

Enables users to more easily add external programs to the Cube Base program menu

7


New in Cube Base:multiple model appliers

Allows to set available keys (parameters, file options, etc) for several model user types along with separate passwords

8


New in Cube Base:merge catalogs

Merge Applications, Keys and Scenarios from other Catalogs

9


New in Cube Base:direct 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 Voyager:PT 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 Voyager:PT ‘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

Documentation:‘How To’ sheets Recently hired professional, full-time

technical writer. First product is available:

– ‘How To’ sheets:• How to change network projection• How to customize the cube interface• How to enable true shape display• How to use the calibrate gravity model

Next product updated tutorial After that: new Cube User Guide—for

release in June 2007

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

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

Cube 5.0: Cube Land Innovation in land use pricing—via

auction/bidding theory Econometric-based model Integrates Cube Voyager’s transport

accessibility measures and ESRI’s 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

• 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

Cube 5.0 – Embedded ArcGIS

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

22


Cube Web – Reminder…how 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

25


Cube Web – live demonstration

Part 3: ‘Administrator’

log in as the administrator view the ‘clients’ (make up 5 or so) add a new client specify their ‘rights’
