Quoted By:
LRT underground or elevated (not pictured)
All car/bus traffic one-way; direction alternates each street/ave.
Short-trip busses feed outlying areas to LRT stations.
Pedestrian skywalks in dense urban/commercial (not pictured). Could be linked to elevated LRT platforms.
I like the pedestrian skywalk system because it creates a strong deliniation between the rich and poor, reinforcing the social class system.
