A PTAL approach to measuring changes in bus service accessibility

Accessible transport systems are essential to ensure equal opportunities for all people in society. The need for information about transport disadvantage is now a key policy requirement and 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 System (GIS) and ACCMAP enable the analysis of transport disadvantage and accessibility. This paper provides an analysis of the Citybus Network in Northern Ireland and assesses the spatial impact of a hypothetical network change on populations residing within the Citybus network area.
