Hello Ravi,<br>
<br>
I am specialized in this matter. I have developed a system to do all
kind of firebrigade calculations:<br>
<br>
- Area of coverage determined by matching drive times from all the
stations:<br>
<img src="cid:part1.07090909.06030101@zeelandnet.nl" alt="" height="454"
width="603"><br>
<br>
- Determination of best location for new firestation (dark blue area
being the best suitable location):<br>
<img src="cid:part2.09010407.09040603@zeelandnet.nl" alt=""><br>
<br>
And more. In order to do good, realistic modeling for firebrigades you
need datasets that have:<br>
- firestation locations<br>
- vehicle types and vehicle start locations<br>
- target locations<br>
- General description on basic firebrigade SLA (minimal requested time
of arrival)<br>
- SLA matched to individual buildings or area's<br>
- target location fire-vehicle needs (for instance with or without
ladder)<br>
- Dispatch time (time needed between the emergency number accepting a
call and dispatching a vehicle)<br>
- Response time (time it takes the crew to get equiped and in the
vehicle)<br>
<br>
And most important of all:<br>
- A road network that is fine-tuned for fire-vehicles (bridges that
can't be crossed, special thru-ways, and so on)<br>
<br>
If you got all this data in place, you need a routing module and
prepare all kind of extra calculations.<br>
<br>
Please let me know if I can help you any further.<br>
<br>
<br>

type="cite">Hi,<br>
planning to locate fire stations in an urban area.<br>
1. Each fire station will have to cover 10 km from its location.<br>
2. Other fire stations to be placed to reduce duplication and the
entire town is<br>
within -10km- for an emergency call.<br>
<br>
Please suggest 'postgis query', on a line network of roads for the town.<br>
<br>
Cheers<br>
