t seems that the Emergency shelter situation for Hurricane Irma is very
dynamic with over 200 new shelters being opened in just one day.
Apparently the Red Cross have released an app (using Google Maps) that
tracks the emergency shelters and also indicates which ones can't accept
new evacuees

I think that information critical to safety needs a higher level of
verification than just peer review.
So the argument comes down to what is critical information.

My concern is that if these are permanent features, then people will say
"ooh - they'll be the same as last time" and of course they probably won't

Hi Eric,
I noticed that in one of the briefings , the Govoner of Florida mentioned
that Goggle was going to dynamically change their "evacuation routes",
should one become unavailable.
Will this proposal contain alternate evacuation routes, and an indication
by whom and when they would be

Yes, I agree , this one is silly and means nothing. They are always open,
and if closed will be just deleted from the map.

The list of emergency centers would be very much dependent on where the
threat is and what the nature of the threat is.
Therefore I see these as being loaded (by the relevant authorities) only
when a state of emergency is declared and only for the areas affected.
These locations would therefore

"The social facility shelter

mentions emergency shelter."
Yes it does, although I would think that these would usually be of limited
capacity and meant for use at all times.
I think we need tagging for large scale

"I think amenity=shelter is well established "
Yes, I read that but saw that it said "a small place", so it doesn't seem
appropriate for disaster relief situations.

Do we have a tagging scheme for emergency shelters to be used in times of
natural disasters?
Off the top of my head I could see tags such as
emergency=shelter
protects_from=
wind
flood
radiation/nuclear fallout
fire
earthquake
bomb blast
pet=yes/no
bed=yes/no
water=yes/no
food=yes/no
My suggestion is only for intersections.
U_turns along a road are a whole new ball-game and are dependant on inter
carriageway markings that are not normally tagged. I think these turns are
best left to the driver, the map-data and the router should ignore them.
Cheers

What would be really easy and flexible would be to tag u_turn=no on a node.
This would mean that this node is not allowed to take part in a u_turn
manouver either as part of a from a to or a via. Since most traffic light
intersections seem to be all 4 way no u_turn, all we need is one tage on

A car travelling westbound on an undivided road is about to cross a
north/south divided road at traffic lights.
We wish to prevent the car from doing a U-turn at this intersection.
Do we have to put in two no_u_turn restrictions, one for each of the
north/south carriageways.
If we only need
Would it be a reasonable solution to have area defaults tagged into the
boundary relation/polygon that defines that area. (e.g an administrative
boundary).
For example, we could have values similar to
"unsigned residential ways" - maxspeed 50
U-turn at traffic signals yes/no
unsigned motorway
Hi,
Apparently, in Australia the default rule at traffic lights is that u-turns
are not permitted.
At some ,there are signs saying " U Turn permitted". How do we tag this.
Turn restriction seem to be either mandatory (only) or prohibitive (no)
but I think we need a permissive one, maybe
