Abstract

Previous studies have highlighted the need for tools to assess the impact of interventions on the bus network and the accessibility of the system. Geographical information systems and a travel access and travel time mapping package called ACCMAP enable the analysis of transport disadvantage and accessibility. This paper provides an analysis of the Citybus Network in the Belfast area of Northern Ireland and assesses the spatial impact of a hypothetical network change on accessibility within the Citybus network area. The impact of these changes on different age, car ownership and religious groupings as measured by the Public Transport Accessibility Level approach is also examined. Findings indicate that mapping the accessibility of the Citybus network clearly shows the spatial impact of network changes in different time periods. In this case study, hypothetical network changes are shown to have a disproportionate impact on older people.
