Some people feel this solution is too car-centric, and does nto provide for pedestrians. What they fail to realize is that if cars can travel on different roadway levels, people can too. That's why Hyderabad has numerous foot overbridges u/c, and has already opened them in Secundrabad, Begumpet, and Dilsukhnagar. The Dilsukhnagar FOB is particularly notewrothy, for it has become quite popular with the area's schoolchildren, who like walking above a busy road.
This is also safer than a standard crosswalk, since there is no chance of anyone getting run over by stray cars.
The solution to improving traffic flow is to safely increase the maximum throughput, not blind faith in rules that ultimately lead to frustration in dense conditions.
