TOI Nov 25,2009 - We pay for defective Signals

Read the enclosed article as published in TOI, Delhi on Nov 25,2009

According to this, Delhi police pays Rs 270/- per signal per month. Cost of electricity is fixed at Rs 4.68 per unit.

Now there is a plan to add meters on each light so that only actual energy is paid for.

However a simple calculation done by an engineer who has designed traffic controller exposes the intelligence of Delhi Police and other concerned persons.

Here is the calculation

Wattage per traffic signal (assuming four roads) - 100W
Daily consumption - 100W X 16 Hours
+ 50 W X 8 hour = 2000 W
Daily charges assuming it works round the clock - Rs 4.68 * 2

This is Rs 9.36 per day or Rs 280.80 per month

Just think the cost of reading meter, parking vehicle on red light (that will be illegal as red lights have no parking places), generating bills, cost of replacing defective meters (meters will also go bas as frequently as lights go bad), cost of some one verifying it.

In short great job



Monthly charges = 11.32 X 30 days = Rs
