  We conduct a preliminary investigation into the levels of congestion in New
Delhi, motivated by concerns due to rapidly growing vehicular congestion in
Indian cities. First, we provide statistical evidence for the rising congestion
levels on the roads of New Delhi from taxi GPS traces. Then, we estimate the
economic costs of congestion in New Delhi. In particular, we estimate the
marginal and the total costs of congestion. In calculating the marginal costs,
we consider the following factors: (i) productivity loss, (ii) air pollution
costs, and (iii) costs due to accidents. In calculating the total costs, in
addition to the above factors, we also estimate the costs due to the wastage of
fuel. We also project the associated costs due to productivity loss and air
pollution till 2030. The projected traffic congestion costs for New Delhi comes
around 14658 million US$/yr for the year 2030. The key takeaway from our
current study is that costs due to productivity loss, particularly from buses,
dominates the overall economic costs. Additionally, the expected increase in
fuel wastage makes a strong case for intelligent traffic management systems.
