Urban mobility in perspective: new perspectives on the dynamics of the contemporary city

of

The rapid increase in the mobility of people and goods is reshaping the urban fabric, often in a context of urban fragmentation, health crises and climate change, challenging planning and daily life in cities.These transformations demand an in-depth review of how we conceive and use our urban spaces.In Latin American cities, challenges such as accelerated population growth, inadequate urban planning, limited transport infrastructure and dependence on individual vehicles are emphasized by Vasconcellos (2001), resulting in congestion, pollution and increased travel times.He points out that many large cities in developing countries have adapted in recent decades to the efficient use of the automobile, a movement strongly linked to the interests of the emerging middle classes in the process of capitalist accumulation.At the same time, there has been a decline in the public transport system, the result of an approach aimed at discouraging its use as the main means of motorized transport.
In Brazil, the critical situation of too many vehicles, daily traffic jams and increasing air pollution demands urgent attention.The lack of investment in sustainable alternatives, such as bike lanes, nonconventional fuels and effective fare integration, in favor of efficiency in public transport, exacerbates this problem, disproportionately impacting the most vulnerable populations.On the other hand, some cities have adopted significant urban mobility projects, including the creation of exclusive bus lanes and the expansion of metro networks, as well as investment in complementary and alternative modes.However, the effectiveness of these initiatives is often compromised by the fragmentation of public policies, especially regarding the intertwining of transport and land use, as well as resistance to entrenched cultural changes.
Inertia in the integration of policies and the lack of investment in infrastructure are factors that intensify these difficulties, constituting significant obstacles to the implementation of lasting solutions to the challenges of urban mobility.Faced with this panorama, a critical reassessment of current strategies is essential, prioritizing an approach that is both inclusive and sustainable in urban mobility planning.This is essential to guarantee a future with more opportunities and fairness for all population strata.
In other words, the last few decades have witnessed an adaptation to the intensive use of the car, reflecting a model of privatization of mobility linked to the interests of the elites and the emerging middle classes in the context of capitalist accumulation.Although there is routine criticism of the automobile for generating congestion and pollution, in general what we see is that investments in infrastructure for the automobile still outstrip those for public transport.This leads to unstable and insufficient transport services, which fuels a policy of dissuading its use as the main means of transportation, except for those who have no other option.
In this context of disparities, unequal access to mobility emerges as a critical factor, directly influencing the social and economic inclusion of individuals.Peripheral neighborhoods, often inhabited by poor communities and ethnic minorities, face major systemic deficiencies in terms of transport infrastructure and service, restricting access to key activities such as employment, health and education.
Promoting sustainable urban mobility transcends the mere implementation of operational objectives; it is a fundamental right, reflected in the equitable distribution of the various means of transport, whether motorized or not, and the expansion of access to urban opportunities.However, the persistence of inequalities points to the need to go beyond conventional approaches, adopting innovative strategies guided by the values of democracy, solidarity and social justice.
We can cite a few themes that have sparked research into how cities can tackle the challenges of urban mobility in an integrated and sustainable way: • Integrated Urban Planning: planning that considers mobility from the earliest stages can result in more accessible and sustainable cities (Cervero, 2004 and2013;Glaeser, 2011).
• Mobility as a Service (MaaS): the integration of various modes of transport into a single platform, accessible via mobile apps, is emerging as an innovative solution, encompassing options such as public transport, bicycles and electric scooters, as well as shared cars (Jittrapirom et al., 2017;Utriainen and Pöllänen, 2018).
• Public Spaces and Tactical Urbanism: practical and cost-effective interventions, such as the installation of temporary bike lanes and the expansion of sidewalks, encourage sustainable means of transport and contribute to the humanization of urban spaces (Gehl, 2010;Lydon and Garcia, 2015).
• Policies to Discourage Car Use: measures such as the implementation of urban tolls, low-emission zones and the promotion of car-free days represent effective strategies to reduce dependence on private vehicles (Shoup, 2005;Newman and Kenworthy, 1999).
• Community participation: including the community in decisions regarding urban mobility ensures that the proposed solutions meet the real needs of the population, fostering social inclusion and strengthening the sense of belonging (Litman, 2019;Carmona, 2021).
• Technology and Innovation: the adoption of advanced technologies, such as autonomous vehicles, artificial intelligence for traffic optimization and integrated transport management systems, is key to overcoming urban mobility obstacles (Townsend, 2013;Ratti and Claudel, 2016).
• Active Mobility: encouraging the use of active means of transport, such as walking and cycling, has public health benefits, reduces pollution and improves the quality of life in urban centers (Pucher and Buehler, 2012;Newman and Kenworthy, 1999).
Many of these themes permeate the reflections in the articles in this publication, deepening them or bringing reflections more in line with the dynamics of cities in the Global South, as well as methodologies and case studies that improve new ways of looking at mobilities.This dossier brings together a series of articles by researchers, most of whom are Brazilian, highlighting the complexity and multiple dimensions of contemporary urban mobility and offering innovative perspectives and critical analyses on the subject.The texts address fundamental aspects such as equity, urban segregation, the impacts of health and energy crises, climate change, transport infrastructure, public space planning, transport-oriented development, public policies, planning and governance, technological innovations, active mobility and micromobility, as well as exploring the everyday experiences of diverse groups, differentiated by age, race and gender.In this way, the dossier contributes to contemporary debates on urban mobility and socio-spatial equity, broadening the scientific dialog between researchers from Latin America and other international realities.
To make the dossier easier to read and compose a sequence of interest, the articles are structured into four thematic sections.
The first section, "Views, concepts and dynamics of urban mobility", delves into the various facets of urban mobility, highlighting the understanding of its infrastructures and the discrepancies in access, in a global scenario in which movement and connection are becoming increasingly important.This segment discusses the current mobility background, analyses the relationship between infrastructure planning and territorial dynamics in Brazil, emphasizes the importance of social participation in mobility equity and examines the role of transport networks in urban development and continuing inequalities.
Bianca Freire-Medeiros' article, The metropolis of network capital: socio-spatial mobilities and urban inequities, explores access asymmetries and mobility regimes in highly connected cities.The study introduces concepts such as "dwelling in movement" and "grammar of displacements" to understand the interaction between mobilities, social structures and territories, proposing a critical look at the inequalities generated by these regimes.
Jeferson Cristiano Tavares, in Trajectories of infrastructure in Brazil.Conceptions, operationalizations, and conceptual frameworks in perspective, investigates the challenges between infrastructure planning and territorial dynamics, proposing innovative approaches to infrastructure projects that respect and value local characteristics, with a view to minimizing adverse impacts.
In Social participation and mobility justice in Brazil, Aline Fernandes Barata highlights civic participation in urban mobility planning as an essential tool for tackling mobility injustices, especially in informal settlements.The study contrasts the limited effectiveness of formally established spaces for participation with the effectiveness of community participation spaces, which emerge in response to the inadequacy of official planning.
Thales Mesentier and Romulo Orrico, in Transportation oriented to urban development, reflect on the impact of transport network planning on urban inequalities, suggesting that careful, accessibility-oriented planning can promote more equitable and sustainable urban development, countering the patterns of centralization and decentralization that often perpetuate social disparities.
Section 2, "Urban planning and socio-spatial inequalities", analyzes the relationship between urban planning, mobility and socio-spatial inequalities, also considering the impact of new technologies.The articles in this block deal with the dynamics between urban planning and mobility in São Paulo, socio-spatial inequalities in the city, the role of commuting time in spatial segregation and the effect of transport apps on accessibility and urban mobility inequalities.
