Document Summary
Which of the following was not an orarching theme of andrew currans lecture: Five minute walking distance to commercial services and transit: Five minute walking distance is a key principle. In streetcar city context the 5 minute walk merges to form a linear public space. Most fundamental relationship between people and ghg = density: driving and density. If we want higher numbers of walking and biking instead of transit, we need a specific city form rather. Urban density and transport-related energy: medium density(50-75 people per hectare) Only two types of streets: residential streetso, streetcar arterials, matters because after 1950"s(auto oriented landscape) Vancouver vs surrey(check slides): same size: check number of intersctions(to determine how many trips by car = level of ghg) Density of intersections: intersection density much higher in traditional, dendritic or tree like vs network(web like, dendritic has quite streets and less roads, no alternative routes and highly loads main intersections.
