Table 1
Indicators in node-place-green model.
Description
Calculation of the indices
Node index
Number of directions served by subway
y1 = number of subway services offered at station
Daily frequency of services by subway
y2 = number of subways departing from station on working day
Number of directions served by other public transport
y3 = number of public trfansport services offered at station
Daily frequency of services by other public transport
y4 = number of buses, trams, and underground trains departing from station on working day
Proximity to CBD
y5 = travel time to the CBD
Place index
Restaurant, entertainment, and hotel within 15 minutes’ walking distance
x1 = number of POIs within 15 minutes’ walking distance in restaurant, entertainment, and hotel
Industry and distribution within 15 minutes’ walking distance
x2 = number of POIs within 15 minutes’ walking distance in transport distribution centers and warehouses, private warehouses, gas stations, factories, and crafts
Commerce, finance, and real estate within 15 minutes’ walking distance
x3 = number of POIs within 15 minutes’ walking distance in commercial corporations, banks, real estate agency, communication, newspaper, and broadcasting
Education, health, and culture within 15 minutes’ walking distance
x4= number of POIs within 15 minutes’ walking distance in hospitals, social insurance, social welfare, all kinds of schools, research institute, skill classroom, and government office
Administration and services within 15 minutes’ walking distance
x5 = number of POIs within 15 minutes’ walking distance in travel agencies, amusement parks, gardens, public bathhouses, and temples
Land use mixture
x6 = 1−((a−b)/d)−(a−c)/d)/2
a = max (x1, x2, x3, x4, x5)
b = min (x1, x2, x3, x4, x5)
c = mean (x1, x2, x3, x4, x5)
d = x1 + x2 + x3 + x4 + x5
Green index
Low vegetation cover
= the ratio of low vegetation area to building area
