Furthering Less Congestion by Creating Opportunities For More Walking and Cycling

The FLOW project focuses on urban road transport, analysing the role of pedestrians and cyclists.


  • The aim of the research team is to achieve a paradigm shift by putting walking and cycling on an equal footing with motorised modes. Non-motorised modes of transport should be recognized as an effective means to alleviate urban congestion. This overall objective will be achieved through a transdisciplinary approach along with state-of-the-art tools for assessing the impact of pedestrians and cycling on congestion busting.


  • Congestion assessment methodology

    PTV contributes to this paradigm shift through the elaboration of the FLOW congestion assessment methodology including a multimodal congestion definition and a set of multimodal indicators measuring direct and wider consequences to assess the effectiveness of walking and cycling measures in congestion reduction.

    Modelling and impact assessment

    The core of PTV´s contribution corresponds to the improvement of the existing transport simulation software (PTV Visum, PTV Vissim and PTV Viswalk), as well as the development of a socio-economic impact assessment to better analyse the impacts of walking and cycling measures on the road transport network performance, and thereby on congestion.

    Capacity and network building

    The user-friendly FLOW methodology, together with the state-of-the-art modelling and assessment tools, will be directly applied to and tested in the FLOW cities network throughout Europe.
