Split (white line with diagonal white lines) actually extends past San Pedro per last survey.

Some changes here are based on personal knowledge, but, I forgot to add them on the sources on JOSM.

Likely these are PLDT street cabinet. They should be re-tagged as man_made=street_cabinet with street_cabinet=telecom.

Looking over other roads with the Primary tag, this would be Trunk rather than Primary, as it is the most important road among the other Primary roads (Quirino Avenue/P. Diego Cera Avenue, CAA Road, Marcos Alvarez Avenue, and Investment Drive and Daang Hari). How it can be Primary. Is it due to the designation (secondary)?

You are welcome for any feedback. I will continue to map other jeepney routes around Batangas City, and also bus routes to Manila etc.
