Hi Marloue,

JP Laurel should generally be a two-way, single-carriageway. there are only
cats eyes/lane markers there, no center islands nor barriers (like those in
front of Victory Mall)...

dual carriageways that are not really one in reality will make navigator
suggest routes that loops or other paths directly opposite the lane due to
the presence of the barrier or ways not linked to the other carriageway.

I already found the error before I came there (to Bajada View in front of
SSS Bajada) and verified if JP Laurel is really a dual-carriageway. the only
segment of Laurel as dual-carriageway is in front of Victory Mall (where a
no-left-turn to the service road should be placed), near the Bajada
Interchange and a segment near C.M. Recto.

on East Avenue, it's really a dual-carriageway with center island and steel
barriers in the middle, recently passed there again last saturday just to
eat at Little Quiapo. I only remembered i have to add a no-left-turn from
Matalino to East Ave (then use a U-turn slot to get to EDSA). I've no
updated info on NIA road though but I remember it as dual-carriageway with a
center island.

lastly, i add errors to openstreetbugs :P


I explore, therefore I blog.
