9 months ago This is an expansion/further development from the "P-factor" method Cost function GC[i,j] = Time[i,j] ppm + Dist[i,j] ppk + Toll/fare[i,j] or rewritten as GC[i,j] = Dist[i,j] + Time[i,j] * ppm/ppk + toll/fare[i,j] / ppk
We need:
- NTS analysis to understand whether we can extract travel costs from NTS in addition to distance to produce observed trip-cost distribution.
- Also need to understand whether NTS sample allow it, quality of NTS sample
- Also need the "supply framework" to produce distance, time, and fares for the purpose of trip-cost distribution gravity model
Include ways for the model to run from generalised cost rather than purely distance.
