Regional Transport Models

Regional Models are often characterised by their size and composition. They cover a much larger area than intra models, containing significant rural components, and are populated by two or more larger settlements. They are typically used to model provincial cities (such as Whangarei, in New Zealand) and corridor towns on the margins of much larger cities (such as Wollondilly in Australia). GPC have built and maintained several such models, including:

Napier-Hastings, New Zealand

Napier and Hastings are cities located on the east coast of the North Island in the Hawke's Bay. They have a combined population of 120,000 and form the hub a thriving agricultural and horticultural economy. The region as a whole has become known as the "fruit bowl" of New Zealand and has established itself as one of the leading wine producing regions in Australasia. Hastings is known as the main industrial hub of the area while Napier contains a port and is a popular tourist destination.

We have developed a TRACKS Transportation Model that:

We have been involved in modelling the area since 2003. The largest modelling study conducted in the area was the 2004 Hawke's Bay Regional Traffic Study which recommended a substantial road building programme using newly established criteria for project appraisal. The project is noted for its comprehensive coverage of Heavy Goods Vehicle Movements and vehicle emissions modelling. Additional studies include:

Waikato Regional Transport Model, New Zealand

In 2007 Gabites Porter were commissioned to construct a regional wide transportation model for the Waikato region, covering the area from just south of Pukekohe in the north to south of Turangi in the south. This is a large model build and operation project for the seven local authorities in the Waikato under their umbrella organisation LASS, together with Waikato Regional Council and NZTA. The project has involved data collection, three and four step model build (now complete) and a three to five year operations contract.

We have developed a TRACKS Transportation Model that:

We have been involved in modelling most of the region as distinct smaller models for a number of areas over the past 30 years. The content and knowledge of having maintained these smaller models assisted greatly in creating the large regional model. Due to the high level of detail covering Hamilton in the regional model, this model is now used for all modelling work undertaken in Hamilton and the entire Waikato Region. Some of the recent studies include:

Wollondilly, Australia

Wollondilly is a large Shire on the outskirts of Sydney and has a population of 40,000. In recognition of their strategic location they have made significant investments in transport modelling technology to make sure development and traffic growth are planned properly.

We have been involved in the modelling the Wollondilly transport network for approximately 10 years and in that time have contributed to a number of important studies:
