lets start with the unit, Headway.
It is a measurement of the distance/time between vehicles in a transit system.
Most commonly measured as the distance from the tip of one vehicle to the tip of the next one behind it, expressed as the time it will take for the trailing vehicle to cover that distance.
A "shorter" headway signifies a more frequent service from road
vehicles on a freewaycan have as little as 2 seconds headway between them.

an average vehicle size and a distance between vehicles are used to calculate the vehicles per hour.
ie: A Honda Civic and a Toyota corolla are approx 14.5 foot long, put 4 feet space between cars. total is 20 feet.( approx. )
considering the speed limit in Karachi, the roads are designed for 700 vehicles per hour.
According to a study, there are more than 11,000 vehicles per hour on the roads.
Karachi already has more than half the country's 3.5 million vehicles, adds upto 400 new cars a day.

700-11000 = ( - 10300 cars) :-#
How much time, fuel wasted?Yr breathing in polution stuck in traffic jam and how much time wasted filling up those cng tanks.(per month).
Better would be instead of saving on cars sniffing cng on less v/h
work out a better solution to increase vehicles/hour.
