I need to interpolate traffic data consisting in raw number of vehicles passing across certain points, where counters are. It is evident I haven't a uniform distribution of points and values about traffic. I would like to ask which methods I could use to interpolate this network deducing traffic for each location of the overall network. I tried to look on the most used desktop GIS (QGIS, ArcGIS) but it seems there is not a'ready made' solution at the moment. Is there an algorithm that I can implement in Python to achieve this result? Thanks!
