In this estimation question we have analysed the market size of the length of roads in Delhi. Check out the step-by-step answer created by Mobiprep experts.


Estimation Question Step-1: Segmentation

Approach:


We will begin with estimating total area ------> area of the roads ------> length of the roads


Assuming, Delhi to be a square and yellow & blue metro lines run diagonally to each other having an average of 30 stations situated in Delhi with an average distance between then to be 2 km.

Therefore, area of Delhi = 1/2x(2x30)x(2x30) = 1800 sq. km

Area of Delhi

Therefore, area of Delhi roads = 360 sq. km (approx)


Estimation Question Step-2: Solution

Different types of road in delhi

Average width of National = 25 mtrs (they are broadr as they are multi- Highways & flyovers lane highways and expressways)

Therefore, length of road = 0.2x360x1000/25 = 2880 km (approx)


Average width of state = 15 mtrs (they are generally smaller in width than NH) owned roads

Therefore, length of road = 0.3x360x1000/15 = 7200 km (approx)


Average width of MCD = 10 mtrs (they are smallest compare to all) owned roads

Therefore, length of road = 0.5x360x1000/10 = 18000 km (approx)


Therefore, the length of roads in Delhi = (2880 + 7200 + 18000) = 28080 km (approx)
