Ian Clark has over 30 years in transport planning and transport modelling. Between 1987 and 1997 he worked in London, before moving to New Zealand.  Over the last 20 years in New Zealand he has been involved in the transport planning of many major projects throughout the country.  These have included:

  • Studies relating to additional or improved crossings of the Waitamata and Manukau Harbours, both in Auckland
  • Involvement in the redevelopment of Eden Park, for the Rugby World Cup in 2011
  • Responsibility for the transport assessment of the Auckland City Rail Link, including an assessment of the traffic effects in the Auckland CBD during the construction of the project
  • Responsibility for NZ Transport Agency’s Southern Corridor Improvements project (improving Auckland's Southern Motorway between Papakura and Manukau) and the Northern Corridor Improvements project (improving Auckland's Northern Motorway, in the vicinity of the Upper Harbour interchange, and including an extension of the Northern Busway from Constellation station to Albany station).  Both projects are currently under construction
  • Responsibility for the transport planning and traffic modelling for the NZ Transport Agency’s Russley Road/Memorial Avenue project, close to Christchurch Airport, and along one of the Christchurch Roads of National Significance.

Ian is known as an expert in transport modelling.  In addition to overseeing traffic/transport modelling tasks at Flow, he has also acted as the peer reviewer, overseeing the development of transport models for the Waikato region, the Western Bay of Plenty (including Tauranga/Mount Maunganui), Dunedin and Queenstown. 

Ian is regularly called on to provide expert witness evidence to the Environment Court and at Board of Inquiry Hearings.  

Between 2008 and 2016 Ian was the inaugural chairman of the New Zealand Transport Modelling User Group ("NZMUGS"), and he continues to play an active role in the Group, fronting the development of guidelines on travel demand forecasting, and representing NZMUGS on the equivalent group in Australia (the AITPM Transport Modellers Network).
