I am used to using pgr-route driving distance function to calculate how far I can go from a given point to a surrounding area
Assuming that I have a transport graph that includes costs and reverse costs is there any way off generating how long it takes to reach a single point from the surrounding area ? A reverse driving distance ?
The only way I can think of doing this is to calculating the driving time for a series of points around the central point, but that strikes me as a rather expensive way of doing it.
Note my data includes cost and reverse costs values so I can just invert a driving distance calculation.
