32. Analyzing door-to-door travel times through mobile phone data

Author

Abstract

A strategic objective of the European transport policy is the so-called 4-h door-to-door target, according to which, by 2050, 90% of travelers within Europe should be able to complete their journey, door-to-door, within 4 h. However, information on door-to-door travel times is scarce and difficult to obtain, which make it difficult to assess the level of accomplishment of this ambitious target. In this paper, we extract door-to-door travel times based on the analysis of opportunistically collected data generated by mobile phones. Anonymized mobile phone records are combined with data from the Google Maps Directions API to reconstruct the different legs of the trip and estimate the travel times for the door-to-kerb, kerb-to-gate, gate-to-gate, gate-to-kerb and kerb-to-door segments. The travel times of these legs have been extracted for different scenarios, all of them focusing on the Adolfo Suárez Madrid-Barajas airport, with the aim of exploring their influence on total door-to-door travel time. Results show that the methodology presented is able to measure door-to-door travel times and that these travel times measured are far from the 4-h door-to-door target. We finish by outlining future research directions.

Abstract

[EN] During the past decades, the scientific interest on the linear disturbance observer-based controllers has notably increased, mainly, due to their good properties for handling changes or uncertainties in the systems. In this tutorial, these type of controllers are reviewed by analyzing their characteristic elements which are: i) the disturbed models, ii) the disturbance observer algorithms, and iii) the feedback control-laws as well as their main design-techniques. Some aspects of the control theory that motivate and support the use of these regulators are also described, including: the model uncertainties, its relevance within the robust control paradigm, and the capability of the disturbed models to handle uncertainties. The tutorial concludes with an ilustrative example on the closed-loop glucose control for diabetic people (artificial pancreas)., [ES] Durante las últimas décadas, los reguladores lineales basados en observadores de perturbaciones han experimentado un interés creciente entre la comunidad científica, principalmente, debido a sus buenas propiedades para tolerar cambios o incertidumbres en los sistemas. En este tutorial se aborda una revisión de dichos reguladores, analizando sus elementos más característicos esdecir: i) los modelos con entradas de perturbación, ii) los algoritmos observadores de perturbaciones, y iii) el diseño de leyes decontrol , así como sus principales técnicas de diseño. Se consideran también algunos aspectos de la teoría del control que motivan y justifican la utilización de estos reguladores; principalmente: la incertidumbre de los modelos, su importancia dentro del paradigma del control robusto y la capacidad de los modelos perturbados para representar sistemas inciertos. El tutorial concluye con u nejemplo ilustrativo sobre el diseño de este tipo de reguladores para el control de glucosa en personas diabéticas (páncreas artificial)., Este trabajo ha sido financiado por la Union Europea-Next Generation EU –proyecto Margarita Salas, MS/38, Universitat Politècnica de València, Ministerio de Universidades, España.
