30%
minimum greenery share for a favourable streetscape impression
Most people have a favourable impression of the streetscape when more than 30% of the view consists of greenery
Research cited in this study indicates that when greenery makes up more than 30% of what people see in a street view, the majority of observers form a favourable impression. This threshold has implications for urban design standards in residential neighbourhoods, suggesting that maintaining adequate green cover in the visual field is important for perceived environmental quality.
According to Aoki [38], most people have a favorable impression of the streetscape if more than 30% of the view consists of greenery.
