Topic outline

  • Project Summary, Objectives and Expected Impacts

    TANGENT improves knowledge and management of mobility flows among a range of transport modes. In addition, it enables the implementation and integration of innovative mobility solutions, services, and business models. The project contributes to more efficient traffic management, facilitating multimodal networks, accelerating the transition towards connected and automated mobility, reducing pollutant emissions and congestion, improving safety and security, and reducing the cost of mobility for all. TANGENT helps the pilot cities achieve a 10% reduction travel time, 8-10% reduction in CO2 emissions, 5% reduction of accidents, 10-15% increase in use of public transport.


    • TANGENT has received funding from the European Union’s Horizon 2020 Research and Innovation Programme, Grant Agreement No 955273
    • The budget amounts to 4.8 mill. euro
    • TANGENT started in September 2021 and will run over 3 years
    • The partners represent seven European countries: Belgium, Germany, Greece, Italy, Netherlands, Portugal, Spain, United Kingdom
    • The cities involved are Lisbon, Great Manchester, Rennes, Athens

    Case studies:

    • Rennes: Fostering intermodal cooperation of passenger and freight transport in urban areas

    It has a wide digital infrastructure to provide information on traffic and transport network use. In TANGENT, Rennes aims at gathering and process data from different stakeholders (public and private) and provide various schemes for data-sharing among them based on current standards (e.g., NeTEx, DATEXII) and extensions to guarantee interoperability and improve intermodality.

    • Lisbon: Integrated urban and interurban transport management with C-ITS

    TANGENT aims to integrate data sources from multiple stakeholders, process them and disseminate current and future status of the network, incidents, speed, route, and park & ride recommendations to users through different channels. It will do so by (i) optimizing interurban flows on highways by speed and route recommendations through C-ITS for connected vehicles, (ii) direct vehicles to unoccupied off-street and on-street parking places, (iii) improve synchronization of urban public transport with incoming inter-urban traffic flows from highways.

    • Greater Manchester: Optimisation of transport flows both in urban and in rural / semi-rural region

    TANGENT contributes to optimising transport both in urban areas and rural/semi-rural regions from Greater Manchester by balance demand and supply across different modes by suggesting different strategies and measures to transport authorities and transport operators (e.g., alternative traffic signal timings, variable speed limits, re-routing, pricing, incentives, etc.) with a particular interest on promoting sustainable modes.

    • Athens: Future transport management with Connected and Automated Vehicles (CAVs) – virtual

    Athens faces severe congestion problems due to the rising demand for car trips. TANGENT aims to provide strategies to improve network connectivity and operation through a better information system that connects all modes. It aims also to significantly reduce congestion levels through the balance of the demand and supply in real-time scenarios. The effectiveness of TANGENT strategies is tested for various future mobility scenarios including CAVs and ride sharing services.
