Looking at adding jam direction. Suggestions for other fields welcome.

Add ew_direction and ns_direction fields to the jams table.

SQL to update existing rows with direction data:

update waze.jams set 
ew_direction =  
case  when (line -> 0 ->> 'x')::NUMERIC - (line -> jsonb_array_length(line)-1 ->> 'x')::numeric  > 0 then 
'W' else 'E' end 
where uuid in (select uuid from waze.jams where 
ew_direction is null limit 100);

 update waze.jams set 
 ns_direction =  
 case  when (line -> 0 ->> 'y')::NUMERIC - (line -> jsonb_array_length(line)-1 ->> 'y')::numeric  > 0 then 
 'S' else 'N' end
 where uuid in (select uuid from waze.jams where 
 ns_direction is null limit 100);
 

Remove where clause to update all of them, though this will take a long time.
