Reshaping Christchurch’s public transport system: The potential of transit orientated development and rail : A dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Planning at Lincoln University

Abstract

Christchurch, New Zealand, is a city with a seemingly forgotten rail history. The city once had an intricate tram system that served much of the city which was removed and sealed over in the 1950s, and a heavy rail system that serviced much of the surrounding Canterbury townships and the South Island which has served only tourists since 1970. This abandoning of the rail network that once shaped the region was due to the rapid uptake of private vehicle usage which was more convenient and cheaper than rail. In recent years studies into the feasibility of reinstating public rail transport have received significant interest from local government and public due to growing concerns about climate change and the city’s urban sprawl. This research will investigate the potential of a public rail network in the Greater Christchurch region of New Zealand and will provide further analysis Rapid Mass Transit options in the region. Literature was reviewed on the current and previous rail proposals for the Greater Christchurch region as well as reviewing successful rail projects internationally. Key informant semi-structured interviews were conducted with members of the Christchurch City Council/Greater Christchurch Partnership, Environment Canterbury and The Ministry of Transport to ascertain the key barriers and enablers of implementing a rail system in Christchurch. A quantitative analysis calculated the possible ridership numbers of an comprehensive Greater Christchurch region was also conducted using ArcGis, Census Commuter Data with Excel-based equations. This helped create a key research finding of an upper limit of 376,063 daily trips or 137,262,995 yearly trips that could be moved by rail between the catchments as defined within ArcGis. Other key findings highlight the importance of transit orientated development (TOD) in the success of rail whilst highlighting the success of new rail is at the expense of other transportation modes such as private vehicles. This suggests restricting cars in densified zones such as the central city being key to influencing a mode shift. Additionally, a change in mindset is also needed from the public to adopt public transport and from planners to find better ways of examining the potential success of rail through Cost-benefit analysis.
