Hello Ravi,

I am specialized in this matter. I have developed a system to do all
kind of firebrigade calculations:

- Area of coverage determined by matching drive times from all the stations:

- Determination of best location for new firestation (dark blue area
being the best suitable location):

And more. In order to do good, realistic modeling for firebrigades you
need datasets that have:
- firestation locations
- vehicle types and vehicle start locations
- target locations
- General description on basic firebrigade SLA (minimal requested time
of arrival)
- SLA matched to individual buildings or area's
- target location fire-vehicle needs (for instance with or without ladder)
- Dispatch time (time needed between the emergency number accepting a
call and dispatching a vehicle)
- Response time (time it takes the crew to get equiped and in the vehicle)

And most important of all:
- A road network that is fine-tuned for fire-vehicles (bridges that
can't be crossed, special thru-ways, and so on)

If you got all this data in place, you need a routing module and prepare
all kind of extra calculations.

Please let me know if I can help you any further.
