Mumbai has given me my friends, education, bread, happiness & sorrow – I love it. But with that it has given us traffic & pollution – 2 things unavoidable in this city. Despite of the patient Gaurav Samant driving me to work on that crazy JVLR, both of those rankle me everyday. But over the last couple of months, I’ve come to conclude that the traffic problem in Mumbai is a mere flow-rate issue. I might have lost touch with the intricacies of fluid dynamics, but the flow rate concept is simple enough to recollect & apply here. Wider roads have more cars flowing per second (wider area allows high velocity, hence higher flow rate). And its exactly the opposite on narrower roads. When 2 roads come together to form a road narrower than the sum of their widths, theoretically cars would have to go faster to keep the flow-rate constant. But I wish Mumbai roads allowed this. Such joints are usually where traffic clogs due to damaged roads & lack of driving sense.
The first problem is that these devastated intersections are “No Contractor’s Land”. Continue reading Mumbai traffic, the continuity equation & polictical will
