What We Do

Transport Modelling

Flow is acknowledged as a leader in the field of transport modelling in New Zealand.  Ian Clark is the chairman of the New Zealand Transport Modelling User Group (NZMUGS), and Terry is on the NZMUGS committee.

Flow applies advanced transport models and modelling techniques to evaluate a wide variety of transport schemes and to assess the potential effects of proposed land use developments.  We are experienced in using a variety of modelling packages and have licences for the following software packages:

  • SATURN, a suite of transport network analysis programs for the simulation and assignment of traffic on urban road networks 
  • S-PARAMICS, a micro-simulation traffic modelling package 
  • SIDRA, a package for the simulation of traffic at isolated intersections,  
  • TRANSYT, a package which is used to examine series of closely spaced signalised intersections 

These programs allow us to examine a wide range of issues, from area wide strategic studies through to detailed assessments.
