Abstract: Travel surveys are used to estimate the percentage of citizen using certain mode(s) of transport, and are the basic building block towards data-driven transport policies. Traditionally, travel surveys are done on paper or with telephone assistance, a costly and cumbersome approach that limits the number of times the survey can be applied. The advent of ubiquitous Smartphones opened the door for the implementation of travel surveys as a mobile app that (i) collects relevant sensor data (ii) uses Machine Learning models to detect the transportation mode, and (iii) interface with the user to verify the machine's prediction, correcting it if necessary. In this talk I will present a general framework for mobile travel surveys, review the associated challenges and research questions associated to each phase, and present some of the advances we have made in the context of the H2020 QROWD project.
