I would like to optimize the service areas / catchment areas for an emergency service. Therefore, I have several measurement points on the streetmap, where people have stopped the travel time from base station to these points.
All roads are classified in 6 different classes (e.g. motorway, path). Now I would like to set up a linear optimization to solve the average speed per road type. Is this linear speed optimization possible in systems like PostGIS and QGIS? Any tutorial or knowledge? Otherwise I would implement it in Mathematica, which is not optimal since all my data is already in the GIS.
Before I decided to do this, I searched for data average speed vs. road type on the net. However, there seems to be no scientifically thorough data on this topic? Maybe one on this board knows any data or report? I mean, it should be available, since all routing suppliers have those data...
@Editors: Could someone add a new tag "emergency services" and optionally tag all questions on this topic like this? I think there is a growing user base on this (advanced) topics.
