Hey there, again. As you see, I am going on about this alphabetically
I added the speed limits I read in the law text for Iowa in the table under (US-IA) here https://wiki.openstreetmap.org/wiki/Default_speed_limits now, but there are some unclarities for me. Perhaps (someone from Iowa) can help me there?
1. Unclear rule
So, there is this:
I am having difficulties to understand (4). So, the default, if nothing else applies, is 55 mph, but during night, it is 50 mph on secondary roads that are not paved with with asphalt or concrete?
(And then, what are secondary roads? It is not defined in § 321.1 Definitions of words and phrases)
2. Are “school districts” always just signed as such, or is the speed limit that applies for these school districts also signed?
If the speed limit that goes with school districts is always signed, this rule doesn’t need to be in the OSM default speed limits table.
3. How would a driver know that he is in a “suburban district” (and not in a residence or other district)? (45 mph)
“Suburban district” is also not defined in § 321.1 Definitions of words and phrases. Or, again, will there always be speed limit signs at the borders of these districts?
4. How would a driver know that he is on a “state park or preserve drive”? (35 mph)
(Or will speed limits always be signed?)
5. How would a driver know that he is on an “institutional road” ? (45 mph)
(Or will speed limits always be signed?)
I am asking for each item whether these default limits will actually always be signed because of § 321.289 Speed signs — duty to install. I am not sure if that paragraph would apply to all of these. If it does, these default speed limits do only matter for the government and not for the drivers (and by extension, navigation systems, maps etc )
