The Evolution of Transport Planning
INRO recognizes special contributions of the planning community, and distributes tools and references related to our software.

Heinz Spiess ran the EMME/2 Support Center in Aegerten, Switzerland until March 2005. His macros and articles are posted here with his permission.

Macros

  • accumvol.mac (1K)
      Accumulate boardings and alightings along the stops of a transit line to produce segment volumes.

  • ang2tpf.mac (5K)
      A macro which sets the turn penalty function index of all turns within a specified range of turning angles to some given tpf value. If required, a subset of turns or intersections can be selected on which the operation is to be performed.
  • angleijk.mac (1K)
      Network calculator formula to compute turning angle of turn I-J-K (returns angle between -180 and + 180 degrees).

  • balance.mac (5K)
      Basic 2-dimensional balancing implemented with module 3.21 (can be used as starting point to implement variants of the balancing procedure)

  • balance3.mac (1K)
      3-dimensional balancing based on group-to-group totals (no limitation on the number of 3rd dimension constraints).

  • balmprod.mac (8K)
      2-dimensional balancing for the case of multiple production types (each with its own friction matrix) and a single attraction type.

  • balz3x3.mac (5K)
      Simultaneous 2-dimensional balancing (aka "Fratar", "Furness", ...) of 3x3 matrices - one for each selected zone.

  • bellman.mac (2K)
      Bellman's shortest path algorithm implemented in module 2.41 (can be used to compute node-to-node shortest path trees).

  • caligrav.mac (4K)
      Calibration of simple exponential gravity distribution model to reproduce a specified target average trip time.

  • congtras.mac (12K)
      Congested transit assignment (see the corresponding paper for a mathematical description of the method).

  • demadj.mac (13K)
      Auto demand adjustment procedure based on the gradient method (version 2.2).This version supports count data on links and/or turns. For a mathematical description of the auto demand adjustment procedure implemented in this macro see the corresponding paper.

  • demadjt.mac (13K)
      Transit demand adjustment procedure based on the gradient method (version 1.8). This version supports count data on either segments or links. Depending on the type of attribute containing the counts, the gradient algorithm is either applied directly at the segment level or automatically projected to the link level. For a mathematical description of the mathematical method used, see the corresponding paper.

  • errchk.mac (2K)
      Wrapper macro to check for errors during execution of the macro given as argument.

  • intersad.mac (5K)
      Marco which automatically adds to or removes from the intersection table all nodes for which a given network expression yields a non-zero result.

  • legimped.mac (3K)
      Extract 1st leg impedance matrix (Upk) or 2nd leg impedance matrix (Ukq) from a given total impedance (Upq) and a intermediate zone matrix (Kpq).

  • listscal.mac (3K)
      List one or several ranges of scalars either on the screen or into a specified file.

  • matreg.mac (14K)
      Multiple linear regression on arbitrary matrix data (up to four independent variables).

  • mimoleg.mac (7K)
      Logit type intermediate destination choice model for mixed mode trips (e.g. Park+Ride or Kiss+Ride) which computes intermediate demand matrices for the first and the second trip leg. No explicit capacities at intermediate destinations. See the corresponding paper for the mathematical details.

  • mlus92.mac (8K)
      Implementation of German air pollution model MLuS-92.

  • netdiff.mac (8K)
      Macro which compares two scenarios and reports differences in network topology, that is, nodes, links, turns, transit lines and transit lines segments which are in one scenario but not in the other (version 1.3). Optionally, the macro can also compare the values of specified numerical attributes.

  • nethist.mac (7K)
      Macro for generating arbitrary network histograms. Supports numerical output on screen or into result file, as well as plotting of the histogram using module 4.13.

  • netreg.mac (14K)
      Multiple linear regression on arbitrary network data (up to four independent variables).

  • oppvol.mac (5K)
      Macro to compute opposing volumes on turns based on turning angles (can easily be modified to include other classification information, if needed).

  • parkride.mac (8K)
      Logit model for Park+Ride parking choice with explicit capacities at parking lots. This macro computes intermediate demand matrices for the first and the second trip leg. See the corresponding paper for the mathematical details.

  • pltlines.mac (3K)
      Plot transit line(s) in an optimally adjusted network window.

  • rndabout.mac (10K)
