Presentation Transcript

  1. Major New Features of Cube 4.1 • Cube Base • dynamic bandwidths, node/point, colors • dynamic intersection displays • email model status • geoprocessing to calculate transit access • wizard for adding user programs • multiple model applier types • function to merge catalogs • direct read of binary networks and matrices (Cube Reports) • Cube Voyager • PT select link • PT ‘mustusemode’ and ‘bestpathonly’ • Documentation • New How to Sheets • Two new extensions • Cube Avenue – extension to Cube Voyager providing mesoscopic dynamic traffic assignment • Cube Cluster – extension to Cube Base bringing distributed processing to Cube

  2. 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

  12. 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 Essential Cube Cube User Guide

  13. 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

  15. New Extension for Cube Base: Cube Cluster

  16. A peek at Cube 4.2 & 5.0Key Technologies in the Lab

  17. 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 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

  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

  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’
