WHAT IS B_us? As a new solution to estimate OD-M of transport and to design tailored bus routes, the project B_us (commercial name of the project FitYourBus, funded by the European Commision H2020 programme frontierCities) proposes a new way of collecting and treating mobility pattern data in order to reduce about 36% the cost of data acquisition and 41% the cost of exploiting data, allowing the deployment of user-driven transport services. METHODOLOGY The proposed methodology includes the following stages: 1) Platform. Deployment of a back-end service and its administration interfaces. The data collection setup is based on a client-server architecture using J2EE and Docker technologies. 2) Data collection. Users provide their basic commuting data-origin, destination, work hours, etc-using our cross-platform smartphone app, which communicates with the back-end service.FrontierCities de la Comisión Europea (H2020)No data 2018UE
