Facing the democratic urban planning challenges, geographers and city planners have developed a new urban approach, new investigating methods and productive dialogues. Since 2018, a team of researchers at Lille University of Sciences and Technologies (TVES laboratory) have participated in designing and experimenting digital tools for collecting spatial viewing data, across French and foreign territories. The aim is to promote numerical tools to optimize a comprehensive and sustainable urban planning which will also help handicapped population. Numerical tools contribute therefore more and more to improve the design of urban planning, which are supported by both technology and diversity of information. Which scientific and operational contributions could be brought in? Are they responsible for a comprehensive and sustainable urban planning? Are they able to engage new stakeholders (citizens) in the decision process? The GEVU numerical tools, innovation supports and new partnerships participate to include end-users in the co-construction of inclusive urban design.
