Why density matters? Walking in high walkable Perth neighbourhoods 2.79 times higher than low walkable neighbourhoods Walking by residents living near high walkable Melbourne neighbourhood activity centres (densities of 28 dwellings/hectare) 9 times higher than in low walkable activity centres; and those living near moderately walkable activity centres (20 dwellings per hectare) 2.75 times higher In Melbourne neighbourhoods with densities 30-39.9 dwellings/hectare (gross), walking trips 2.52 times higher and public transport trips 2.99 times higher than low walkable neighbourhoods; at 20-29.9 dwellings/hectare cycling 5.58 times higher and motor vehicle trips halved.
