While there haven't been a decision on revising the existing
classifications
for roads, I am also considering discussing a tagging scheme for implied
speed limits (those not indicated by a sign). I have been experimenting
with tagging of those unsigned speed limits on some of my last edits, but
I'm also thinking of a standard for the country.
The default speed limits for the Philippines (as codified in the Land
Transportation and Traffic Code or Republic Act 4136) are as follows
80 kph (50 for heavy trucks and buses) - "open country" roads
40 kph (30 for trucks and buses) - "through" roads within built-up area
30 kph - "non-through" roads within built-up areas
20 kph - crowded streets
In addition, many major rural roads may have lower implied limits (e.g. 40
kph) due to factors such as pedestrians walking on the road, and some major
urban roads may have a higher limit (e.g. 60 for multi-lane roads or other
roads where pedestrians don't frequently cross or walk alongside vehicles).
Expressways are not covered by RA 4136, but there seems to be these
defaults (almost all of these explicitly marked by standard circular signs):
100 (80 for heavy trucks and buses) - rural
80 - urban
60 - minimum
These defaults, in turn, corresponds to these possible values for OSM
(along with the corresponding numeric value:
- PH:rural - 80
- PH:urban - 30 (minor through roads within cities/municipalities,
generally those classified tertiary), 40 (all other major roads), 60
(higher-quality roads, generally multi-lane)
-PH:living_street - 20 (note: includes anything classified unclassified,
residential and service, not only those classified living_street)
Important questions are:
1.) How should we handle the RA 4136 categories: source:maxspeed= or
maxspeed:type=?
2.) Is this already a fine proposal, or this may need some tweaking?
