- ItemA bumpy ride: structural inequalities, quality standards, and institutional limitations affecting cycling infrastructure(Elsevier Ltd, 2022) Tiznado-Aitken, Ignacio; Mora Vega, Rodrigo; Oyarzun, Gabriel; Vergara, Jaime; Vecchio, GiovanniStructural socio-economic and institutional limitations can affect the implementation of cycling infrastructure. More stringent cycling infrastructure standards aiming to solve deficiencies might exacerbate disparities, especially in poor districts with fragmentary governance. Using an audit and quantitative and spatial analysis of cycleways, this paper examines to what extent structural inequalities and governance issues affect the availability and quality of cycling infrastructure, considering new indicative and normative standards aiming at improving cycling infrastructure in Santiago, Chile. Our results show that the distribution of cycleways is unequal and only partially complies with national quality standards. All districts in the city have both high and low standard bicycle lanes, but since district finances have huge differences, this can lead to inequalities in cycle coverage and districts' capabilities to address current standard problems. This raises relevant challenges regarding governance and how to ensure an equitable distribution of cycling infrastructure in Global South cities.
- ItemFair transport policies for older people: accessibility and affordability of public transport in Santiago, Chile(SPRINGER, 2022) Vecchio, Giovanni; Tiznado-Aitken, Ignacio; Castillo, Bryan; Steiniger, StefanIn this paper, we test how different public transport policy scenarios score in terms of fairness for a specific population group, considering a more complex representation of mobility-related inequalities and the policy implications of transport justice. To do so, we assess potential accessibility to public transport in Santiago de Chile under different policy scenarios, focusing on older people as a group whose demographic and socioeconomic conditions can determine different forms of disadvantage. We compare alternative accessibility policies based on the expansion of the Metro infrastructure network or on reduced public transport fares, considering the interaction between the spatial availability and the affordability of public transport. Results show that subsidized fares for public transport services are more beneficial to expand the accessibility of older people, especially those with lower incomes, while the expansion of the Metro network benefits mainly middle- and high-income older people. The proposed analysis is a first step towards a more detailed, place-based reading of mobility-related inequalities, aimed at assessing alternative policy measures.

- ItemUnequal periurban mobility: travel patterns, modal choices and urban core dependence in Latin America(Elsevier Ltd, 2023) Tiznado-Aitken, Ignacio; Vecchio, Giovanni; Guzmán, Luis A.; Arellana, Julián; Humberto, Mateus; Vasconcellos, Eduardo; Muñoz Abogabir, Juan CarlosLatin America is a highly urbanized region characterized by remarkable inequality levels, also reflected in an uneven distribution of opportunities, making socio-economic segregation quite visible. Since the individual possibility to travel and therefore access to urban opportunities strongly depends on socio-economic status and the distances to overcome, highly unequal patterns of mobility and accessibility emerge. The continuous expansion of Latin American cities originates specific mobility-related inequalities visible in periurban areas, which tend to lack some key urban opportunities and public transport services usually available in cities. Due to established and new patterns of territorial segregation, these areas may generate new forms of marginality in relation to mobility, posing challenges for public action and territorial governance. Our paper considers if and how periurban areas experience different forms of mobility-related inequalities in three Latin American metropolises in Brazil, Chile, and Colombia (São Paulo, Santiago, and Bogotá, respectively). We do so by examining the differences among urban core and periurban zones based on four elements: socio-demographic features, access to the public transport system, spatial continuity, and functional dependence. Our analysis shows that the three metropolitan regions have different structures: while Bogotá and Santiago appear to be more dependent on the urban core, São Paulo shows more autonomous and self-sufficient periurban zones. The analysis also highlights different forms of peripherality, defined by differentiated mobility patterns and modal choices that suggest that city-specific lines for public action might be needed.
