Article
Unequal access to urban opportunities is a challenge for planners and policy makers, particularly in cities of the Global South. This study investigates inequalities in accessibility in São Paulo from an individual-based perspective, adopting a methodological approach that overcomes the high computational and data requirements that typically hinder...

Este estudo apresenta um diagnóstico de como o uso do transporte individual motorizado e do transporte coletivo tem evoluído desde o início dos anos 2000 nas cidades brasileiras. Nós analisamos dados sobre mudanças no padrão de consumo de bens e serviços de transporte, o aumento de renda das famílias, além da evolução dos custos de transporte urban...

Routing is a key step in transport planning and research. Nonetheless, researchers and practitioners often face challenges when performing this task due to long computation times and the cost of licensed software. R5 is a multimodal transport network router that offers multiple routing features, such as calculating travel times over a time window a...
Conference Paper
Full-text available
This paper presents a study on ethno-racial segregation in London based on residence to workplace flows. An agent-based model is used to simulate the trajectories of individual agents belonging to different population groups, which are aggregated into flow patterns (or 'collective footprints') of each group. The model highlights spatial segregation...

Resumo Os processos de formação de áreas de pobreza nas periferias urbanas são fenômenos multifacetados, compostos pela influência de numerosos agentes com ações estratégicas e vinculados à diferenciação e à segregação socioespacial. Ciclos de crescimento e redefinição do valor da terra inserem a forma urbana nesse contexto, ampliando a segregação,...

Full-text available
This work is committed to verifying the capability of an accessibility measure to identify areas prone to high urban growth, related to the presence of higher locational advantages. This issue is addressed via urban modelling, using techniques of urban growth simulation based on cellular automata. Accessibility measures have proven effective in stu...
Conference Paper
Full-text available
It is well known that movement patterns have an influence in urban form and land use distribution in cities. The paper presents the AXS Model, which generates an aggregated movement pattern from the bottom-up using an agent-based modelling approach. The aim of the AXS Model is to replicate global urban patterns, such as the ones generated by access...
Conference Paper
Full-text available
This study explores the use of the CNEFE dataset (National Cadastre of Addresses for Statistical Purposes), recently made available as part of the Brazilian 2010 Census, which provides land-use information in individual level and national scale for the first time in Brazil. The study analyses the relationship of land-use distribution and urban morp...
Conference Paper
Full-text available
This work proposes an urban growth simulation model based on a weighted accessibility measure, which is calculated based on the characteristics of the landscape surrounding the city. Two types of features were considered: natural and human-made. The model was tested for the city of Bagé, in the Southern Brazil. The model was largely able to replica...
Conference Paper
Full-text available
The study of the complex dynamics that engage urban form presents powerful instruments to understand the driving forces of contemporary urban development. This research intends to test traditional urban growth tendencies against informal development mechanisms and decision-making behaviors of competition in geosimulated environments. The empirical...

Resumo As formas da natureza sempre foram motivo de admiração e fonte de inspiração para a humanidade em suas mais diversas manifestações artísticas, inclusive na Arquitetura e no Urbanismo. A dificuldade de projeto e execução de formas orgânicas em objetos destinados à vida humana conformou forte empecilho ao longo da história e foi enfrentada por...

Resumo O trabalho apresenta resultados da investigação sobre as relações entre o desenho das bacias e das sub-bacias hidrográficas e o zoneamento utilizado no planejamento da área urbana, em Pelotas, a partir de fundamentos de planejamento ambiental e de ecologia de paisagem. A pesquisa se divide em duas fases: a primeira fase é dedicada ao mapeame...

This work seeks to advance urban research through computer simulations based on unequal development theory, the capitalist production of space, complexity theories on urbanization and computer urban growth dynamic modelling. Initial findings demonstrate an enduring existence of conflict in city form social appropriation in capitalist-determined urban development processes, pointing to contributions on social and city form roles in urban simulations, while suggesting an improvement in urban growth modelling capacities through the specification of particular observations on the modelled environment.
Project
In a context of rapid urban growth, cities across the world are increasingly defined by inequality. RESOLUTION: REsilient Systems fOr Land Use TransportatION, a collaborative project between Brazilian and British academics, explores the impacts of unequal access to transport on different social groups in London and São Paulo. To this end, the team will build agent based models of how populations compete for travel and location. Through a comparative study of these two world cities, the project will identify similarities and differences between them to tease out the broader social implications of transport access on mobility, segregation and other trends. The research will include a particular emphasis on how resources are distributed depending on class, ethnicity and income. The results will be of relevance to a range of stakeholders, including policy makers, academics and planners, working on improving opportunities for marginalised groups through more equitable transport systems. As the focus is comparative and global, the findings will have broader implications not only for London and São Paulo but also other large cities facing the same challenges.
