I'm using San Francisco dataset offred by OpenStreet map and I'm trying to get the optimal path using 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 diveded into many segments. enter image description here

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