Subject: [OSGeo Africa] Travel Time Calculation

Dear All

I have a problem that I hope someone on this mailing list could assist with.
I want to calculate travel time from (each) VILLAGE to the nearest URBAN CENTER along the road network.
The output format could be text or GIS with at least 3 columns: 1. Village, 2. Nearest Urban Centre and 3. Travel Time.

I have 3 data sets: 1. Villages (Point), 2. Urban centers (Point) & 3. Roads (Polyline/line) for the whole country (Namibia).

I would appreciate if someone refers me to tutorials on this.
I have access to PostGIS, QGIS and GvSIG, ArcInfo, GeoMedia Pro 6.x, MS SQL Server 2008 (Spatial) but am willing to try something else.

Rgds,
Uazu
