Many of us living in Delhi-NCR
have cumulatively spent hours waiting at the NH-8 Delhi-Gurgaon Toll Plaza.
I ran a short calculation as I
was waiting at the toll plaza this Saturday afternoon.
How much it costs you as a car
owner:
· Average waiting time for each car (to get from
end of queue to toll point) = 10 minutes
·
Rule of thumb: For every 2 minutes spent idling,
your car consumes the same amount of fuel it takes to go one km.
·
Average mileage of Car= 10 km/l or 0.1 l/km
·
Delhi Petrol price = Rs 70/ liter
·
So in 10 minutes of idling your car consumes = (10/2) x 0.1 liters = 0.5 liter of petrol = Rs 35!
·
Total cost of crossing toll plaza = Idling cost
+ Toll = 35 + 21 = Rs 56!
How much it costs us as a
community:
· Number of lanes = 18 each way
·
Total number of lanes = 18 X 2= 36
·
Average Number of cars waiting in each lane= 25
·
Total Number of cars idling at the Toll plaza at
any given time = 25 x 36 = 900
·
From the previous calculation, each car is
consuming 0.1 l every 2 minutes of idling = 0.05 l/min
·
Fuel being exhausted by all idling cars at toll
plaza = 0.05 x 900 = 45 l/min!
45 liters of petrol
are being poured down the drain EVERY minute at the Delhi-Gurgaon toll plaza!
The situation gets worse at night
time when the idling vehicles are trucks which are even less efficient. If we
consider 8 hours of such traffic each day, the toll-plaza consumes 21,600 liters of petrol a day.
Any technological recommendations
to solve this problem? The tag lanes don’t seem to be working very well.
