Measuring the Impacts of Economic Well Being in Commuting Networks - A Case Study of Bogota, Colombia

Big data such as call detail records (CDRs) from mobile phones are novel resources for travel demand models. An important open question is how to use them to extract practical information in relation to urban mobility, socioeconomic development, and well-being. Can we study individual mobility characteristics by income group through the lens of Big Data? In this paper, the authors present a data analysis framework that uses urban mobility extracted from CDRs, to study various characteristics of the commuting network of Bogota, Colombia, relating them to income groups by their residential location. They show that the diversity of commuting trips, defined in terms of entropy of the trips, increases with the income of the population. Further, they show that vehicle travel times during commuting hours from lower income groups clearly suffer longer congested travel times. The authors' results detail a method to use passively generated mobile phone data as a low cost alternative for transportation policies that can benefit from economic well-being measures for population with different income levels.
