From: Unravelling the spatial directionality of urban mobility

a–c Hourly anisotropy and centripetality of urban mobility for a strong monocentric cities (n = 36), b weak monocentric cities (n = 13) and c polycentric cities (n = 11). Symbol sizes indicate the relative trip generation volume per hour. Symbol colours denote different hours. Green and blue signify early morning and late night, with yellow and red indicating midday. Source data are provided as a Source Data file.
