Is there a way to know what version of pgrouting I have?
My OS is ubuntu 12.04.
I want to know my pgrouting version because the 1.05 version has some issues with shooting start and the directed graphs and the last stable version which has this…
I know that pgRouting is a pretty nice tool, but I would like to use something of my own in my application, mainly because I don't know C and I don't know how to tweak the performance of pgRouting. Thus I am interested in how pgRouting's internals…
I'm trying to follow this tutorial,
http://www.pgrouting.org/docs/foss4g2008/ch06.html
but on the step with assign_vertex_id() it shows an error for executing the SQL query:
SQL error:

LINE 1: SELECT…
I'm asking this, because I need some tool to solve a DARP problem.
After researching I found PgRouting had included this functionality in one of its branches. But after installing it, getting stuck and looking for other people problems similar to…
Following the pgRouting workshop here, I have the routing query below:
$sql = "SELECT gid, start_id AS source, end_id AS target, the_geom,
distance(the_geom, GeometryFromText(

I am running the shortest_path function but it will not return rows of lines to follow from source id to target id. Is there a specific way to digitise my dataset? Does pgrouting understand intersections between lines? I digitised my lines one by…
I used osm2po to create a table for pgRouting.
I notice a problem: for a route with dijkstra or a* the route is correct and respect the one ways. But with shooting*, it doesn't respect the one ways.
The route is from 11 baulacre geneve (46.2159082,…
We have imported OSM networks to route on. So our IDs sometimes grow abnormally big ;)
It seems that PGRouting is failing with IDs like 633719916...
We got this error message from postgresql:

I'm trying to use pgrouting pgr_trsp function but result is useless. Exactly same code with pgr_dijkstra working OK and find shortest path between start and stop but with pgr_trsp it is look like random jumps around map.
I'm using this code

I'm developing a pgrouting application using navteq information but I don't know how to use the navteq information to add turn restriction in pgrouting. Even, I don't know where to find this kind of information in the navteq tables. I guess this…
I have used this great tutorial, and shortest part between two points works fine.
My question is:
How to calculate shortest path between multiple points?
I have an existing pgrouting network topology that I would like to add a road to. The road is a linestring from a shapefile and will intersect several roads in the existing network. Is there an easy way to add the road into 'ways' so it is…
Is pgRouting 1.05 compatible with postgresql9.0 Win32? I am a newbie, and I have spent three days trying to build it for postgresql9.0, but without success in the end.
Thanks.
Yes, you are right. I am using postgresql 9.0. Building all of those…
I think I have found a major issue with pgrouting. I hope I am just doing something wrong due to my inexperience.
I am plotting the following query using OpenLayers.
select transform(the_geom, 900913) from dijkstra_sp_directed('ways', 52343, 39219,…
