  • What\'s new in Visum 11.5

    1. 1. WWW.PTVap.COM Vikas Sharma VISUM 11.5 3rd PTV Asia Pacific Vision User Group Meeting 2010
    2. 2. 2© PTV AP 2010 Many more operations are faster... > If you use a multi-core computer > Headway based public transport assignment > Time matrix calculations (Skimming) > Select link analysis (Flow Bundle) > Vehicle scheduling for PT operations (Line Blocking) > This is in addition to already converted operations > Timetable-Based PuT Assignment > PrT Lohse Equilibrium Assignment
    3. 3. 3© PTV AP 2010 Private Transport: LUCE is fully launched... > VISUM’s new, faster, Equilibrium Assignment is no more a prototype (LUCE) > All post-assignment operations available > Skim matrix calculation (along minimum-cost paths or volume-weighted averages), > Flow-bundle (select link), > TFlowFuzzy matrix estimation, > Blocking back, > Path listing, including drawing paths in network view > ANM Route export, > Warm start > …
    4. 4. 4© PTV AP 2010 Private Transport: Assignment with ICA > You can mix HCM2000 based node impedance and a static assignment based on Turn VDFs (ICA Assignment) > The program re-calibrates Turn VDFs based on ICA  Find this at: Calculate/Procedure/Create/PrT Assignment/Assignment with ICA Assignment using user-defined VD functions for turns ICA (HCM 2000) Smoothed turn volumes Parameters of volume-delay curves
    5. 5. 5© PTV AP 2010 Private Transport: Assignment with ICA > New assignment method > Native integration of former script solution > Based on either Equilibrium or Equilibrium Lohse > LUCE will follow as soon as warm start is available > Wraps also relevant settings for blocking back and ICA > Related Improvements > Blocking back reports actual and demand flows simultaneously > Blocking back optionally based on turn capacity instead of / in addition to link capacity > Normal („non-ICA“) assignment can run with turn-specific VDFs from last ICA-assignment > Improved SATURN to VISUM network importer 5
    6. 6. 6© PTV AP 2010 Assignment with ICA
    7. 7. 7© PTV AP 2010 Assignment with ICA
    8. 8. 8© PTV AP 2010 Private Transport: Toll Assignments > Easy toll assignments when tolls are > Area based • VISUM takes care of double-charging avoidance > Matrix based • VISUM takes your load of gate-to-gate links volume synchronisation between virtual and real links  Find this at: 1. A New Network Object: ‘Toll Systems’ 2. Calculate/ Procedure/Create/PrT Assignment/Procedure/TRIBUT-Equilibrium Assignment/Parameters 3.

    9. 9. 9© PTV AP 2010 Private Transport: Toll Assignments > Road Pricing in Highway Assignment > Classical: Impedance = Travel Time + 1/VoT * Toll + … > More realistic: Multiple demand segments, each with its own value of time > Much better: Continuous distribution of VoT all attractive time / toll combinations > Tribut > Method developed by INRETS VISUM 6.5 > Request 1: faster! > Request 2: straightforward modelling of different road pricing schemes
    10. 10. 10© PTV AP 2010 Private Transport: Toll Assignments > Link Toll > Some links in the network carry a toll. > Amount per link and tsys. > Toll for a path = sum toll over all links on path
    11. 11. 11© PTV AP 2010 Private Transport: Toll Assignments > Matrix toll > Subnetwork with gates > Toll = f(in-gate, out-gate) > Toll can be degressive with distance  cannot be expressed as link toll
    12. 12. 12© PTV AP 2010 Private Transport: Toll Assignments > Area Toll > Spatial area > Tool = Flat fee independent of distance > Each trip across area boundary costs > Internal traffic in toll area may or may not be charged
    13. 13. 13© PTV AP 2010 Public Transport > PT Vehicle Scheduling > A new Viewer > More powerful optimizer • Vehicle substitution • Minimizing dead kilometres • Regularly formed schedules • Fit vehicle capacity to assigned passenger volumes  Find this at: Timetable Editor/Block view PuT line blocks > Individual time matrices for various demand segment > Impedance and choice can also be customised for each demand segment  Find this at: Calculate/Procedure/Create/PuT Assignment/Parameters/Demand Segments
    14. 14. 14© PTV AP 2010 14 Public Transport Fares >Fare Model in VISUM 11 > Influenced by European practice > One person trip  one ticket > One VISUM Model  one uniform fare system (per DSeg) >New in VISUM 11.5 > Multiple fare systems within single model, for different operators, areas, … > One person trip  several tickets > Within one fare system, multiple tickets (e.g. normal fare + short-distance fare) > Matrix fares, aka relational fares  Find this at: Network/PuT Fares
    15. 15. 15© PTV AP 2010 More constraints for matrix estimation - TFlowFuzzy > Flows across screen-lines > Trip length frequency distribution > Line volumes > Boardings/ Alightings > With or without transfers  Find this at: Calculate/Procedure/Create/Matrices/Demand Matrix Correction (TFlowFuzzy)
    16. 16. 16© PTV AP 2010 Emission Modelling using HBEFA and ARTEMIS > A set of emission factors from Germany, Switzerland and Austria (HBEFA 3.1) > More countries joining-in > Systematic descriptors for traffic situation (ARTEMIS) > Assessment and Reliability of Transport Emission Models and Inventory Systems > Simplifies mapping from transport models to emission models > Urban/Rural, road hierarchy, free flow speed and LOS > Readymade as well as customisable fleet composition > Enables localisation > Cold/ warm start distinction also possible > Output can be exported as shape file for more detailed modelling  Find this at: Network/Fleet Compositions AND Calculate/Procedure/Create/Miscellaneous/HBEFA based emission calculation
    17. 17. 17© PTV AP 2010 Scenario Management (Part 1) > Text files to transform one scenario to another > Capture addition, deletion and changes > Covers supply as well as demand data > Syntax similar to net files – no learning curve > Users only need to maintain one base model > And many small ‘deltas’ describing various scenarios > Can be applied in succession > Next release will have a GUI > To manage all scenarios rooted to a base model  Find this at: File/Compare and Transfer Networks/ <Create OR Apply> Model Transfer File

    24. 24. 25© PTV AP 2010 Other conveniences... > Import SATURN networks > Use UNICODE characters even for attribute codes, names, file names and paths > Complete (disaggregated) attributes available for connectors > Link orientations can use 8 (or 16) cardinal directions > POI attributes can be inherited to its sub-categories
    25. 25. 26© PTV AP 2010 Perspectives >Future development after VISUM 11.5: > Scenario Management Part 2 > More GPar dialog usability improvements > Improved Calculate Procedures dialog > Support for HCM 2010 in ICA > OpenStreetMap import >We will also explore options for: > Cloud computing > Mesoscopic simulation MEZZO 26
    26. 26. 27© PTV AP 2010 27 Demand Model Improvements >Plans for VISUM 12.0 > Better parameter dialog for demand model operations • Less nesting • More settings visible at one glance • See immediately which settings are still missing • Better Copy & Paste in parameter grids > Calc – Procedures dialog and selected parameter dialogs become modeless and may remain open while executing procedures or in parallel to network / matrix view  faster workflow during model calibration > Improved 4-stage demand model • Nested logit model for destination, mode & macro time period choice • Choices in any order • Absolute and incremental model forms • PA and OD
