These segments were then reviewed, and refined to reflect situations where: </div><div><ul><li>The volume or type of traffic using the corridor changes significantly </li><li>The physical form of the corridor changes significantly i.e. steep terrain, narrow lane widths, windy alignment. </li></ul></div><div>Within the larger urban centres (Auckland, Hamilton, Tauranga, Wellington, Christchurch and Queenstown) the state highway networks have been grouped together to reflect the fact that the highway corridors form part of more complex urban transport systems involving multiple mode and route choices. In this situation it is more appropriate to consider the highway corridors as part of the whole system, rather than focusing on individual corridors. <br /></div><div><br /></div><div>Elsewhere, where a state highway corridor passes through a city (an urban centre with a population over 50,000), a segment has been created extending from one side of the city to the other. This enables the attributes and insights to be targeted to reflect the urban setting and the wider range of routes options, modes and trips occurring along these corridors. </div></div></div>
