Reports

This chapter discusses reports you can prepare with CUBE Analyst. Topics include:

Summary of Reports

The Analyst reports described in this chapter are saved in a print (*.prn) file during program execution. The reports include:

  • A listing of input parameters and options, and input binary header information.
  • Mean, minimum, and maximum confidence levels set by the user for each type of input data are given.
  • Memory requirements.
  • A report of each iteration of the optimization process, during execution in interactive mode. This shows the current value of the objective function, the gradient tolerance, and the sum of all the estimated matrix elements. These values for the last five iterations are always reported.
  • On completion, CUBE Analyst provides summary reports on the comparison between sets of input data and the corresponding estimated values, with the confidence levels that apply. Where relevant data is input to CUBE Analyst, these reports are produced giving comparisons for prior and estimated:
    • Matrices — Matrix totals
    • Trip ends — Zone generations and attractions, with input zone generations and attractions
    • Link flows — Screenline volumes and input screenline volumes
    • Part trips — Part trip ”matrix” totals, distinguished by line groups, where appropriate.
  • Finally, Analyst provides a return code indicating problems during execution, or a successful completion. The codes are:
    • 0 = Normal Termination
    • 4 = Warning. Review the print file and find the (W) tag for information on the warning(s).
    • 8 = Fatal Error, Non Immediate Termination. Review the print file for information on the error(s).
    • 16 = Fatal Error, Immediate Termination. Review the print file for information on the error(s).

Further information may be obtained by using CUBE programs to report on the estimated matrix file.

For an estimation using part-trip data, the output network file contains detailed information on estimated part-trip link flows (equivalent to an assignment of the estimated Part Trip matrix).

CUBE Analyst reporting for hierarchic estimations

CUBE Analyst reporting for a hierarchic estimation varies according to whether the estimation is for a district or a local matrix. The reports for district estimation are the same as for other levels, except, of course, the results apply to districts rather than zones.

For local matrices, CUBE Analyst additionally provides summaries of the row and column side constraints from the district matrix, and equivalent values from the prior matrix. The first reported ”zone” corresponds to the Rest-of-the-World (RoW), while the other reported zones are the set of zones relevant to that local matrix. No screenline reports are produced for local matrices.

The execution log file is output by the optimization step of CUBE Analyst, and three levels of report may be produced. These are controlled by the IREP parameter. The contents of the log file will not normally be of interest to general users, but are of assistance in summarizing the progress of the calculation should investigation be required.
