Hey PhoenixofMt,
Could you finish up adding the SL to I-90 E and N / US-191 S and N. My editing area stops just outside Livingston. Double check all exits, they’re improperly labeled. US-89 Terminates here and begins here. US-10 no longer exists in Montana. US-191 Exits at and begins in Big Timber. Thanks
Sure. By the way, at some point coming down the hill towards Livingston the SL bumps to 80mph. I haven’t nailed down the change point yet, but the segments attached to this exit should be safe to set this high.

What are the guidelines for exit speed limits? If the ramps are short they may have signs for 25 or 15 mph to show you need to quickly decelerate to about this speed to make a sharp curve or short stop. The normal-sized ramps seem to just be “stop ahead” mph. Around 40 - 45 seems reasonable, or do we just want to follow the signage?
Based on what Alan has stated “based on what I’ve read recently, I would concur that ramps and some at-grade connectors should not have their speed set” The signage before a ramp merely advises drivers as a caution to what is a safe speed.
Are we going with the “Truck” speed limit (65)? Because the default freeway speed limit is 75, and it’s 80 east of Livingston.
75/80. If we set a lower limit, regular passenger-vehicle Wazers would be getting limit dings constantly. Truckers are responsible for their tighter regulations. Maybe at some point we’ll be able to do vehicle type and special-lane adjustments (like POV lanes).
I agree with what herrchin posted. 75/80. It’s difficult to know exactly where the 80 SL begins at certain parts on I-90/I-94 unless you live in and around the area. For instance I know the route between G.F and Helena. There is some fuzzy documentation from some newspapers on the internet that suggest where the SL are at but still not a great reference.
That’s what I thought. I ask because it’s set to 65 around Bozeman and it should be 75.
It goes up to 80 coming down the hill into Livingston from the west. I still haven’t nailed down where (maybe this weekend.) I’ve confirmed it’s 80 up to Park City. I wouldn’t be surprised if it was 80 all the way to North Dakota, maybe slowing down for Billings.
There’s also a bit between Bozeman and Three Forks that’s 80, but I’m not sure exactly where.
This Missoulian article has some detail for western Montana. You might be able to correlate mile marker references with some of the state maps, but I guess east-of-the-divide doesn’t matter to the hill people.
With fuel as cheap as it is, I might have take a few recognisance road trips.
I believe I set it to 65 for the reason that MDT says that once you enter a urbanized population SL drops to 65. If you know where about we can fix it.

Except for the areas referred to in the news, I’m 99.9% sure it’s 80 everywhere except where they pass near/through some urban spots.
Only areas you have to be careful are through mountainous regions or canyons following the contour of a river/stream due to its curves. Although the majority of people will loose coverage in these areas.

I think that’s only for non-restricted-access highways. The posted limit is 75 between exits 305 and 313.
I was surprised how many curves were still ahead of the change to 80 going down to Livingston. I thought they’d at least wait until the bottom of the hill. And it didn’t slow down for any populated areas I passed through before I turned around in Park City.
Is it 80 after 313?
Not for a long ways. I’ll drop a UR next to the sign.

I finished it off to Billings. You can close that UR and not sure why this UR is still open? Sometimes the reason is loss of GPS signal. Waze tries to pre-load the map for you, but in this case I assume the GPS lost signal and tried to reroute you back on track.
Done.
I left it open in case some developer was interested. The general feeling seemed to be that no one was sure why the “avoid freeways” feature exists and no effort would be put into fixing it.
The client instructed me to exit the freeway far in advance from both directions – it wasn’t a GPS problem. You can see the directions to exit, U-turn, and get back on the freeway.
Guess I missed the “Avoid Freeway” part.
I dropped some more URs between Bozeman and Butte.

I suppose it’s about due time we come to a concensus about speed limits on our secondary hwy’s traveling through counties on back roads like this. We know that these can change due to seasonal conditions. Although during the summer I’m doing about 55 :lol:
I’m thinking 35mph
Isn’t the legal limit 70 even though that’s probably not an advisable speed? We shouldn’t program in advised speeds… That’s not what the app warning is for.
