• Abstract summary: This paper models the federal road network in Brazil as weighted networks. We aim to unveil its topological characteristics and identify key locations (cities) that play important roles for the country through 75,000 kilometres of roads. Our findings aim to bring clarity to the overall structure of federal roads in Brazil, thus providing actionable insights for improving infrastructure planning and prioritising resources to enhance network resilience.

• Abstract: Understanding how transportation networks work is important for improving connectivity, efficiency, and safety. In Brazil, where road transport is a significant portion of freight and passenger movement, network science can provide valuable insights into the structural properties of the infrastructure, thus helping decision makers responsible for proposing improvements to the system. This paper models the federal road network as weighted networks, with the intent to unveil its topological characteristics and identify key locations (cities) that play important roles for the country through 75,000 kilometres of roads. We start with a simple network to examine basic connectivity and topology, where weights are the distance of the road segment. We then incorporate other weights representing number of incidents, population, and number of cities in-between each segment. We then focus on community detection as a way to identify clusters of cities that form cohesive groups within a network. Our findings aim to bring clarity to the overall structure of federal roads in Brazil, thus providing actionable insights for improving infrastructure planning and prioritising resources to enhance network resilience.

  Inferring the full transportation network, including sidewalks and cycleways, is crucial for many automated systems. This work begins to address this problem at scale by introducing a novel dataset of aerial satellite imagery, map imagery, and annotations of sidewalks, crossings, and corner bulbs in urban cities. We present an end-to-end process for inferring a connected pedestrian path network map using street network information and our proposed dataset.

During the parameter configuration stage, instead of solving the global optimization problem, we design a local multi-objective optimization strategy.

  We investigate the relationship between the spatial scale of the modelled network entities against the amount of useful information contained within it. We employ an entropy measure from complexity science and information theory to quantify the amount of information residing in each presentation of the network. We find the critical spatial scale to be 85 m, at which the network obtained corresponds very well to the planning boundaries used by the local urban planners.
