Transport investments, especially infrastructure like roads, railways, and bridges, last for generations. This means that today’s investment decisions need to anticipate how future generations may want to live and move around and also consider changes in the environment, technology and society.

To support this, the Ministry of Transport has developed the Generational Investment Approach, or GIA, which takes a 30-50 year view of investment choices. GIA enables organisations investing in the transport system to work together to identify and prioritise future choices at the earliest stage in the investment cycle. This complements the existing 3-10 year planning cycle by allowing decision-makers to see how current investment choices align with possible future needs.
