Mobility in modern cities: looking for physical laws
نویسندگان
چکیده
We discuss an exponential law for the trajectories distribution in a urban road network, that has been found analyzing a large set of GPS data on private cars dynamics. This law appears to be common for very different cities, from the size of a town to that of a metropolis. We propose to explain this behavior as an effect of the activities sprawling in modern cities, associated with the existence of a cognitive proximity concept that determines the citizens mobility requests. We discuss the relevance of these results for a complex systems approach to urban mobility.

Structural Analysis of the City Semiology (Case study: Yazd City)
Integration and coherence within a city’s physical structure have become an issue for towns and cities as theyrapidly expand, incorporate new elements, and undergo incessant changes. At present, we are facing an extensive accumulation of signs and traits in modern urban patterns; many unaccustomed to and incongruous are affecting the socio-cultural and physical characters of cities. Here, we wi...
متن کاملCities, Institutions, and Growth: The Emergence of Zipf’s Law
Zipf’s Law characterizes city populations as obeying a distributional power law and is supposedly one of the most robust regularities in all of economics. This paper shows, to the contrary, that Zipf’s Law only emerged in Europe between 1500 and 1800. It documents how Zipf’s Law emerged with the development of markets in the centuries preceding the onset of modern economic growth. It shows that...
متن کاملEntropic measures of individual mobility patterns
Understanding human mobility from a microscopic point of view may represent a fundamental breakthrough for the development of a statistical physics for cognitive systems and it can shed light on the applicability of macroscopic statistical laws for social systems. Even if the complexity of individual behaviors prevents a true microscopic approach, the introduction of mesoscopic models allows th...
متن کاملEvaluating Spatial Interaction Models for Regional Mobility in Sub-Saharan Africa
Simple spatial interaction models of human mobility based on physical laws have been used extensively in the social, biological, and physical sciences, and in the study of the human dynamics underlying the spread of disease. Recent analyses of commuting patterns and travel behavior in high-income countries have led to the suggestion that these models are highly generalizable, and as a result, g...

The purpose of this study was to estimate the effect of gender inequality in education on females’ labor force participation in 14 major cities (rapidly urbanizing areas) of Pakistan after taking into account the socio-economic indicators like the marital status of female, the gender of the head of household, physical facilities, the median income of the household, etc. Data were gathered from ...
