The 20th International Walk21 Conference on Walking and Liveable Communities took place in Rotterdam, on 7-10 October 2019, under the theme: “Smart, Healthy and For everyone”. The future city needs to be able to adapt to transitions with smart urban design and new mobility solutions. Measuring walking and walkability and integrating walking into traffic/transport management tools (e.g. modelling) and decision making, can assure a smart city will always be designed on a human level. At the conference were highlighted examples of evidence, tools, measures and systems that have delivered more walking or better walkability.  The presentations per day of Walk21Rotterdam are available in the following link.
