I'm using San Francisco dataset offered by OpenStreetMap and I'm trying to get the optimal path using the pgr-astar function of PostgreSQL.

I want to find the historical traffic data of San Francisco roads (roads congestion with time slots), that corresponds to the format of the dataset generated by the map so I can calculate the optimal path based on the historical traffic information of each road segment.

Where can I get this data?

This is the dataset of San Francisco, where a road is divided into many segments.

enter image description here

I found many sites that offer the traffic information but it doesn't match my dataset ( without accurate information of the road segment).

You are going to need to process the data yourself. This type of data isn’t collected against osm because there is no guarantee of consistency
