Modelling in FLOW

Nowadays, it is getting more and more important to introduce cycling and walking measures as part of sustainable urban mobility plans, whereby municipalities recognise the long term environmental and social benefits, but also the short-term, congestion reduction potential such measures can bring. However, cities' planning departments are not yet aware of how to model these schemes properly, nor how to accurately assess their impacts prior to their real implementation. 

The FLOW project aimed to overcome this shortcoming by providing a state-of-the-art modelling approach, improved modelling software and improved parameterisation for the representation of sustainable transport modes, which had not been the focus of the modelling community. Through the adjustment of transport software to current mobility trends and simulation needs, it was possible to accurately analyse the congestion reduction impacts of the walking and cycling measures undertaken by the FLOW Partner Cities. 

This overall objective was reached by the extension of the multimodal macroscopic transport planning software PTV Visum, the multimodal microscopic traffic simulation tool PTV Vissim, and the pedestrian simulation software PTV Viswalk, respectively. These developments were achieved in close cooperation with the FLOW Partner Cities - through the incorporation of feedback, the tools were continuously adjusted, which guaranteed the accuracy and applicability to the highest extent.
