Public Transport Accessibility Level and Public Perceptions: A Framework for Urban Mobility Analysis

Source abstract

This study investigates the influence of public transport on the quality of urban life through a combined approach that includes both an objective and a subjective assessment. The objective quality of the public transport network in Timișoara was measured using the Public Transport Accessibility Level (PTAL) index, whose values were recalibrated to better fit the context of an Eastern European post-communist city, while citizens’ perceptions were analyzed based on a public opinion survey in Timișoara, conducted over 5 years on 9490 respondents. The research methods used combine cartography and statistics, with tools such as ArcGIS Pro, IBM SPSS Statistics v27, and R v4.5.2. The results highlight a correlation between accessibility levels and user satisfaction, emphasizing spatial disparities between the city center, which enjoys excellent accessibility, and the periphery, where accessibility is much lower. The integration of these two dimensions provides a holistic perspective on urban mobility and makes relevant contributions to sustainable planning strategies and the development of smart city initiatives.
