The design of a dynamic web-based solution to measure accessibility via public transport under different travel scenarios

An intuitive and interactive opensource web tool for measuring access to services via public transport is described. The application allows policymakers to analyse and compare the impacts that alternative network configurations may have upon access to services. The application facilitates interactive analyses to support decision-makers in making better informed choices. The study addresses key technical challenges to integrating opensource technologies with bus timetable information. A cumulative opportunity measure of access to essential services is computed under alternative real-world scenarios. These consider the complete withdrawal of an agency, the removal of a route, and addition of a new route. We highlight the need to promote the wider use of such interactive tools amongst planners and transport professionals when examining access to services via public transport.
