DESCRIPTION:Speakers: Juan Felipe Alayón Martínez (Universidad Nacional 
 de Colombia)\nPaper published in 2026: we study two years of access card v
 alidation records from Bogotá’s multimodal public transport system\, co
 mprising over 2.3 billion trips across bus rapid transit\, feeder buses\
 , dual-service buses\, and an aerial cable network. From user trajectories
  constructed exclusively from access records\, we derive motifs that revea
 l recurrent mobility patterns extending beyond simple two-location visits.
  This approach enables the construction of an integrated origin–destinat
 ion (OD) matrix covering 2828 urban zones. Similarity analysis using the J
 ensen–Shannon divergence confirms the temporal stability of mobility str
 uctures across semesters\, despite infrastructure changes and fare policy 
 adjustments. From the obtained OD matrices\, we derive transition probabil
 ities between zones and uncover a robust power-law relationship with geogr
 aphical distance\, consistent with Lévy flight dynamics. We validate our 
 model using Monte Carlo simulations showing that reproduces both local and
  long-range displacements\, with similar scaling exponents across time. Th
 ese findings demonstrate that Bogotá’s public transport mobility can be
  effectively modeled through Lévy processes\, providing a novel framework
  for analyzing complex transportation systems based solely on user access 
 records.\n\nhttps://fisindico.uniandes.edu.co/event/23/contributions/324/
