Resumen:
We present a network science approach to characterize accessibility and potential use of parks in cities based on Geographical Information Systems (GIS) and daily individual trajectories cite{salgado2020submitted}. We consider two types of nodes: home regions, which partition the city, and park regions, which are public outdoor/recreational spaces. We build a bipartite weighted network among them, with links´ weight representing the number of possible access from a home node to a park node on an average weekday.We apply the proposed methodology to the Los Angeles Metropolitan area and the Great Boston area, with census tracts as home regions, and park amenities from OpenStreetMaps as park regions. Daily mobility is obtained from TimeGeo, an individual mobility model representative of each city´s total population and based on Call Detailed Records (CDRs).We associate tract´s park access and the park´s potential use to their network strength (sum of links´ weight), founding similar distributions in both cities. The split of the network into communities results mainly in home tracts mostly connect with neighboring geographical tracts.
