It has been associated with rail systems for many years and over the last decade or so has also been used increasingly along the bus network. Yet, existing analysis assessing issues such as the socio-economic characteristics of users of RTPI, the devices used to access RTPI information (i.e. mobile phone, home computer, at stops etc.) and the impact of RTPI on perceptions of public transport reliability and ridership, has received only limited attention in the literature with few studies focusing on the bus network in particular. Accordingly, this paper reports on research conducted to assess these issues with respect to the introduction of real-time bus passenger information in Dublin. The methodology employed was quantitative and consisted of 360 questionnaire surveys with bus users undertaken along specific low, medium and high frequency routes during the peak and off-peak period. The results show that RTPI use correlates with socio-economic status. They also show that most users access RTPI at the bus stops but that those accessing the information via mobile devices are from wealthier socio-economic backgrounds. Finally, the introduction of RTPI at stops and via mobile and internet communications has significantly increased passenger perceptions of the reliability of the service.enPublic transport systemsDublin Bus smartphone appConference Publication2013-08-09https://creativecommons.org/licenses/by-nc-nd/3.0/ie/
