    As cities expand, human mobility has become a central focus of urban planning and policy making to make cities more inclusive and sustainable. Initiatives such as the “15-minutes city” have been put in place to shift the ...
  • A new interior-point approach for large separable convex quadratic two-stage stochastic problems 

    Castro Pérez, Jordi; Lama Zubirán, Paula de la (2020-11-03)
    Article
    Open Access
    Two-stage stochastic models give rise to very large optimization problems. Several approaches havebeen devised for efficiently solving them, including interior-point methods (IPMs). However, usingIPMs, the linking columns ...
  • Investigating the quality of Spiess-like and SPSA approaches for dynamic OD matrix estimation 

    Ros Roca, Xavier; Montero Mercadé, Lídia; Barceló Bugeda, Jaime (2020-01-01)
    Article
    Open Access
    Since OD matrices are not directly observable, indirect procedures have been developed to estimate OD matrices from traffic data. Traffic management must move toward dynamic traffic assignment models because they capture ...
