The key findings of the Auckland Regional Council show that providing efficient PT system combined with some improvements to the road network will be a key element to limit growth in private care use and will be more effective in reducing growth in CO2 emissions (Auckland Transport, 2010).
In New Zealand, the transportation sector is responsible for producing more than 40% of the CO2 emissions and it is the fastest growing source of greenhouse gas (GHG) emissions (Andrew, 2004). A recent study shows that private vehicle transport in New Zealand is less energy-efficient and produces 65% of CO2 emissions in comparison with 15.8% of CO2 emissions from the whole PT sector (Ministry of Transport, 2014). The key findings of the Auckland Regional Council show that providing efficient PT system combined with some improvements to the road network will be a key element to limit growth in private care use and will be more effective in reducing growth in CO2 emissions (Auckland Transport, 2010). More recently, the Auckland Transport Regional Public Transport Plan was created for the purpose of developing an integrated transport network to provide Aucklanders with a sustainable transport system in a safe, integrated and affordable manner (Auckland Transport, 2010). This plan shows the intensive discussion conducted on various issues relating to PT systems of the future. Indeed, a major focus over the next decade will be on enhancing the PT system. Thus, there is need to investigate the performance of Auckland’s PT system to meet sustainability goals.
