[postgis-users] Fire station

Ravi,

I think David Techer posted an excellent PgRouting tutorial way back.
Not sure if you would find it useful.  Its in French

http://www.davidgis.fr/documentation/win32/html/apa.html#id2514001

Google translated to English.

n&ie=UTF-8&oe=UTF-8&prev=%2Flanguage_tools

I haven't tried PgRouting myself so really can't speak much about its
merits.

Hope that helps,
Regina

Hello Ravi!

Thank you for the response. I used to use rwnet from www.routeware.dk, a
very good commercial routing module for windows. 

But I also found pgRouting (openSource and part of OpenLBS) available
for postGIS at http://pgrouting.postlbs.org/
it has the ability to do drive-time analyses which can then be
transformed to cartographic representation on maps. 
I think this module will be very good for you, especially because it
will give you a good insight on the data model needed to do this routing
so you can prepare a dataset for testing.

I am trying this routing module out and will post some samples on my
test website soon.

Please let me know if I can be of assistance!

		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.
