This research project explores concerns about personal security by users of public transport. The findings from an international literature review are used, and the concerns of public transport users in three New Zealand cities (Auckland, Wellington and Christchurch) that have significant public transport patronage streams are explored. Personal security concerns were found to discourage existing patrons from using public transport, and more so after dark. A number of security measures preferred by patrons are outlined. However, the project also found that only a small proportion of patrons actually noticed the presence of security measures that had been installed.
