Trip Assignment

 Highway Assignment

  • Include all-or-nothing, incremental, and user equilibrium assignment methods
  • Include fast tree and vine path builder algorithms
  • Include multiclass assignment, up to 36 modes
  • Include node delay based assignment, using HCM method
  • Include BPR and Conical volume delay functions. User can also define custom functions using link vairables in full qualified expressions.
  • Calculate relative gap values for a high precision convergence in user equilibrium assignments
  • Include select zone analysis, up to 99 zone groups. Individual select zone volumes can be saved separately.
  • Include select link analysis, up to 99 link groups. Individual select link volumes can be saved separately. Select zone analysis and select link analysis can be performed together.
  • Include subarea analysis to produce OD matricies for trips transversing thru cordon links.
  • Include options to perform generazied cost assignment according to value of time and tolls..
  • Include options to save travel distance and toll matrces
  • Include options to save link columes that are constrained by the trip lengths
  • Support multi-threaded trip assignment on multi-core computers. Up to 8 zones can be assigned simultaneously for a speedy run time.
  • Automatically generate assignment scripts for batch processing
  • Include options to perform multi-point assignment with share factor for each inbound and outbound connector.
  • Include options to perform node-to-node assignment
  • Include options to perform additional OD analysis based on slave assignments

Transit Assignment

  • Fast vine based algorithm
  • Include editor for defining transit time functions (TTF) using free form expressions
  • Include weighting factors for walk, wait, and bording times
  • Include options to save travel time skims by element: initial access, initial wai, transfer access, transfer wait, in-vehicle, and total
  • Include options to save matricies of total boarding time and number of boardings
  • Include options for performing select zone, select line. select mode, and select segment analysis
  • Include options for park-and-ride analysis
  • Include options for performing mode pentaly and mode transfer analysis
  • Include options for calculating fare matrix
  • Include options to save OD trips traversing between transit stations
  • Include options to save turning movements at transit stations
