Exploring Invariants & Patterns in Human Commute time [article]

Hongyan Cui, Yuxiao Wu, Stanislav Sobolevskv, Shuai Xu, Carlo Ratti
2015 arXiv   pre-print
For humans, the commute of an individual seems revealing no regular universal patterns, but it is true that people try to find a satisfactory state of life regarding commute issues.  ...  Marchetti states a certain regularity in human commute time distribution - specifically, it states that no matter when, where and how far away people live, they always tend to spend approximately the same  ...  While, what we have presented is still a novel discovery about the commute patterns of modern cities in China. Overall, we develop a methodology that allows us to interrogate human commute behaviors.  ...

The universality in urban commuting across and within cities [article]

Lei Dong, Paolo Santi, Yu Liu, Siqi Zheng, Carlo Ratti
2022 arXiv   pre-print
Our results further show that the scale-invariants of human mobility will ultimately lead to the polycentric transition in cities, which could be used to better inform urban development strategies.  ...  These regularities can be generalized as two laws: (i) the scale-invariance of the average commuting distance across cities, which is a long-awaited validation of Marchetti's constant conjecture, and (  ...  Acknowledgments We would like to thank Meng Li and Hongbin Pei for providing help in data preprocessing.  ...

Exploring Universal Patterns in Human Home-Work Commuting from Mobile Phone Data

Kevin S. Kung, Kael Greco, Stanislav Sobolevsky, Carlo Ratti, José J. Ramasco
2014 PLoS ONE  
One of the key assumptions in this domain of study is the universal uniformity of commute times.  ...  In car-only (Milan GPS traces) and car-heavy (Saudi Arabia) commute datasets, we see that commute time is indeed influenced by commute distance.  ...  The same plots, as cumulative density functions, are shown in Figure S4 for comparative purposes. doi:10.1371/journal.pone.0096180.g002 Exploring Universal Patterns in Human Commuting from Mobile Phone  ...

Evaluating the dynamic impacts of urban form on transportation and environmental outcomes in US cities

S. B. Kashem, A. Irawan, B. Wilson
2014 International Journal of Environmental Science and Technology  
We found that the influence of urban centrality or the strength of urban subcenters on the travel pattern of commuters and transit users is dynamic.  ...  This suggests that people living in cities with stronger centers drive less and use public transportation more over time.  ...  In fixed effects model, the coefficients and errors of time-invariant variables (c and a i ) are eliminated and so, we cannot estimate the influence of those time-invariant factors.  ...

Joint Determination of Residential Relocation and Commuting: A Forecasting Experiment for Sustainable Land Use and Transportation Planning

Jaewon Lim, Jae Hong Kim
2019 Sustainability  
More specifically, using recent inter-county migration and commuting pattern data for the three largest metropolitan areas in California, it examines how residential relocation and commuting are associated  ...  in the regions and whether a unified framework—in which household relocation and commuting flow matrices are jointly determined—can improve the forecasting performance.  ...  Acknowledgments: An earlier version of this paper was presented at the 33rd International Symposium on Forecasting in Seoul, Korea.  ...

Exact Solution of the Gyration Radius of an Individual's Trajectory for a Simplified Human Regular Mobility Model

Xiao-Yong Yan, Xiao-Pu Han, Tao Zhou, Bing-Hong Wang
2011 Chinese Physics Letters  
Gyration radius of individual's trajectory plays a key role in quantifying human mobility patterns.  ...  In this Letter, we propose a simplified human mobility model to simulate individual's daily travel with three sequential activities: commuting to workplace, going to do leisure activities and returning  ...  are nearly invariant.  ...

2003 Transport Survey Quality and Innovation  
Exploratory qualitative research is becoming increasingly commonplace in transportation research, both as a precursor to a traditional, quantitative study, and for the insights it offers by itself.  ...  The purpose of this paper is to illustrate the use of qualitative surveys based on semistructured open-ended interviews to explore poorly-understood aspects of travel behavior.  ...  the study of complex systems such as human activity patterns.  ...

A Theory of Urban Growth

Duncan Black, Vernon Henderson
1999 Journal of Political Economy  
In an economy experiencing endogenous economic growth and exogenous population growth, we explore two main themes: how urbanization affects efficiency of the growth process and how growth affects patterns  ...  In addition, we explore how growth involves real income differences across city types and how urbanization can foster income inequality.  ...  (b) The relative allocation of population across cities is time-invariant.  ...
