This paper details a study of public transport information in Dublin, Ireland.
This paper presents the results of a study undertaken in Dublin, to ascertain preferences among various real-time public transport information options. A survey was conducted of employees in the central business district in Dublin city centre, where respondents were asked to choose between various methods of obtaining public transport information. The survey required that the respondents choose between three methods of accessing transport information across three stages of a public transport trip. The stages examined are as follows; stage one: pre-trip planning from home to work, stage two: at-stop/station information and stage three: pre-trip planning from work to home. At each of these stages the respondents to the survey were asked to choose between several methods of receiving public transport information, via the internet, mobile phone, call centre or at stop real-time information displays. The results from the survey are modelled using the multi-nominal logit modelling approach.
The results in this paper are presented in three sections. The first section examines the impact of the mode of transport most frequently used and current trip features, such as multi-modal trips, wait-time at stop and total trip time. These were examined in the first section to ascertain what if any impact they have upon the choice of real-time transport information option. The effect of work patterns and departure time from origin are analysed in the second section. These variables were examined to establish if flexible work schedules and varying start and finish times impact upon the utility derived from transport information. The final section examines the socio-economic characteristics of the sample. In this section the impact of factors such as gender, age, income and profession are tested to ascertain if they have any significant impact upon choice. The paper concludes with a discussion of the main findings of the study.
