Metropolitan areas are complex spaces, where the concept of accessibility is crucial to ensure high levels of quality of life. However, accessibility analyses have often considered only one transport mode and adopted a ‘static’ approach (no consideration of time). Yet, real accessibility is not static. The measures of accessibility set a common framework to integrate land use and infrastructure, but both urban activities and transport conditions change throughout the day and week. A dynamic approach to accessibility is thus necessary. Further, most of the accessibility analysis have focused on one transport mode. However, understanding the accessibility levels of each transport mode is necessary to predict modal choices and plan sustainable mobility policies. Comparing the balance or imbalance between transport modes is also fundamental to reveal diverse social implications, to evaluate the constraints and disadvantages of who cannot choose transport modes, social equity and cohesion._x000D_
This study analyzes dynamic accessibility by both automobile and public transport and does so in a South American city: Curitiba (Brazil), where academic literature has not been as profuse as for European and North American cities. Analyzing Curitiba not only helps filling that gap, but also implies an assessment of a land use-transport model that has been endorsed as reference for developing cities. _x000D_
Due to high level of social inequality, analyzing accessibility requires special care in Latin American cities, as the consideration of transport “demand” is not homogenous. This study contributes to the literature by combining high-detail, big-data-informed automobile dynamic distance matrixes from TomTom Traffic Stats and a public transport database from GTFS. Accessibility is measured in a dynamic way, taking into account the changing conditions of congestion levels and public transport frequencies, together with the daily variation of mobility patterns.
