I was thinking of connecting the footpaths in the small parks to the roads, to let routers know it's possible to walk through (e.g. if going by foot from 74, Phan Khiêm Ích to 100, Đường số 2, it's faster to walk through the footpaths). I don't have a GPS track though, do you think it's okay if I just connect them perpendicularly to the roads?
