How to calculate the road network distance?

[wzm2256]

Hi, I have read your paper and really appreciate this algorithm, however, I still don't understand how did you calculate the road network distance between two vertex.

I am aware that the road network distance is not spatial distance, but I do not find any further detail in your paper.

Could you please explain how did you calculate the road network distance?

Given the Road Network graph, we use the Dijkstra algorithm to find the shortest paths/distances for each node.

How do you make the Road Network Graph for PEMS data?

Here's an example for calculating the distances using OSMnx and Dijkstra.
