**9.8 City scale: mixed use neighborhoods**

Reducing transportation while maintaining social contacts and the access to urban facilities is a key aspect in preventing and mitigating pandemics. Research done during the 2020 pandemic suggest that "connectivity matters more than density in the spread of the COVID-19 pandemic [98]". The risks are represented by commuting, tourists and businesspeople. Studies emerged during pandemic concern health inequities derived from the urban development [99].

This desideratum can be reached by designing mixed use neighborhoods that could concentrate transportation on walking and bicycling. These neighborhoods are likely to lead to a medium density environments [100]. They should combine living with working, leisure, education and public space encounters.

The concept is not new, as it is already present in Ebenezer Howard's Garden City with self-contained mixed-use new towns and socially mixed population. It is also relevant for the US 1980s New Urbanism or for the European Urban Village.
