“…There are plenty of reasons to model cities. According to the short but comprehensive summary of [8], one of the most important reasons is economic research, including housing costs and firm localization. City models are also necessary for numerous engineering principles, e.g.…”

The present paper shows how a novel autonomous vehicle (AV) algorithm can be tested and evaluated by multiple simulations with different levels of refinement. As the first AVs will appear on our roads (possibly) within the upcoming decade, novel traffic problems, like parking lot assignment, will also emerge. Parking is that kind of activity that will fundamentally change. Today drivers attempt to find parking places close to the destinations to minimize the walking time. The autonomous vehicles will drop off passengers at their very destination, and then, on their own, will seek even a distant parking place. Such change will affect human activities, city traffic, and the parking infrastructure. To investigate this problem we need an abstract city model, because an attempt to create a detailed model of the city traffic from the perspective of decades may be misleading and may lead to false emergent conclusions. We report on such an abstract model and the obtained conclusions in the paper. A question remains how genuine is the introduced future city model. To validate it, we propose to confront it with a detailed microscopic traffic simulation on a road network borrowed from an existing city of corresponding layout and complexity. To this end, we use Eclipse SUMO simulating the traffic of an expansive Budapest district, and show that the results obtained with the simplified abstract mathematical model stay valid.

“…In fact, cities comprise "all the difficulties inherent to complex systems: a large variety of agents interacting with each other, a large variety of temporal and spatial scales, and a large number of processes that modify the spatial structure and organization of these systems." [1]. In this sense, a strong aspect is that it has public transport access, by bus, to the city centre.…”

There are many housing neighbourhoods with no functional diversity, where dwellings are the only function of the buildings. Their inhabitants are out during the day, going to their working places and are coming back only in the evening. Therefore, these mono-functional neighbourhoods, at the suburban parts of the cities, present several problematic aspects, such as in security terms. Consequently, good quality requirements of urban life, are difficult to keep. This paper aims to present the results of an urban project, on behalf on the urban planning subject, at the Architecture studies. The case study area is a peripheral neighbourhood, on the outskirts of the Portuguese city of Covilhã, in the Interior region of the country, near to the border with Spain. The presented solutions are focused on the urban continuity as the main feature to be development regarding the urban fabric, based on the functional diversity of the place. They are proposing new green spaces, new squares as meeting public spaces, cycling paths and pedestrian sidewalks with greenery. The low density of buildings is an option in order to keep the local identity in architectural and cultural terms, and sustainable urban environments, where people can meet each other, stay together and organize events for all community

“…More broadly, this work is part of a nascent effort to study urban systems through the lens of statistical physics. This approach has yielded non-traditional and exciting insights into a wide variety of urban phenomena, including urban sprawl, population dynamics within cities, and growth of cities over time (see, e.g., the reviews by Barthelemy [2,3]). Of particular relevance to the work at hand are recent efforts to quantify the "microstructure" of a city at the level of individual buildings.…”

A central pursuit of micro-and nano-scale engineering is describing the small-scale structure of materials in terms of spatial relationships between positions of particles (representing, e.g., individual atoms). In order to carry out such analyses, molecular simulation practitioners have developed a large array of fast methods to compute spatial relationships on particle-resolved data sets. We have developed a computational workflow that directly applies molecular simulation methods to GIS building data, in which individual buildings (instead of, e.g., atoms) are treated as the particles of interest. In so doing, we enable efficient quantification of "urban textures" consisting of ≫ O (10 3) buildings. This interdisciplinary toolkit potentially opens the door to new vistas for urban-systems modeling. As one of a few early examples, we provide evidence for a novel scaling relationship between size and ordinal rank of building clusters within several American cities, reminiscent of Zipf's Law. This scaling relation suggests a new perspective on fractal-like organization of urban environments.
