Accés obertEste trabajo desarrolla una metodología para alimentar de forma más automatizada un modelo de simulación. Para ello se generó un código de programación hecho con el lenguaje R que: 1) se conecta con base de datos; 2) valida ... -
Transport analytics approaches to the dynamic origin-destination estimation problem
(2020-10)
Report de recerca
Accés restringit per decisió de l'autorDynamic traffic models require dynamic inputs, and one of the main inputs are the Dynamic Origin-Destinations (OD) matrices describing the variability over time of the trip patterns across the network. The Dynamic OD Matrix ... -
