Flow is often called upon to undertake peer reviews of the transport models developed by others. These have recently included reviews of the following:

• The development of a TRACKS transport model for the Waikato region 
• The development of CUBE/VOYAGER regional transport model for the Western Bay of Plenty
• The development of AIMSUN hybrid models for the Western Bay of Plenty, with the meso model covering the same geographic area as the regional model, and with three micro pockets in and around the Tauranga CBD 
• The development of CUBE VOYAGER models of Dunedin, and PARAMICS models of the city centre.
