Temporary road closure

by **daknife** » Wed May 30, 2012 7:50 am

I agree with some measure being needed. A system for reporting and activating temporary closures that don't require map updates. Here in Utah we have our major N/S interstate I-15 getting a major rebuild through one county. Last month two interchanges were closed for a couple weeks. This month two other interchanges are closed, but the time frames of the closures and the still too random map update schedule makes it unfeasible to close those interchanges with the hopes that the closures and subsequent re-openings go live at a reasonable time. Instead I just mark all the UR's complaining about being routed through the closed exits as solved, but I don't like not being able to give any reason behind my inaction to the Wazer who reported it, or being able to effectively manage those closures.

Let AM's be able to set a closure for up to a week at a time, and have that closure go live. Then if the system detects traffic on the closed route or the time expires or the originating or any other AM revokes the closure and the closure goes away.

As to the accident closing the freeway. An accident report followed by the building traffic should effectively trigger the re-routing automatically. Maybe not at the point of the accident or after it, but at the last exit prior to the accident the traffic will be so severe that Waze will route around it. I've seen it happen to me a couple times. I've been told by Waze to get off the freeway miles from my destination and then hearing about the accident on the radio. One time the back-up was within sight of the exit Waze took me off at. So that part works. It also worked during the last marathon in Salt Lake City.

Construction closures is where we need a bit of a feature fix/add-on.

If you close or restrict the road till waze sees travel on it won't work if truck drivers are using waze and hauling using the closed exit. I have a ramp in Chicago that is closed all summer. I set turn restriction but every once in awhile I get a system generated UR for travel on restricted road. I think the workers are using waze as they haul debris away to dump.

You could make it a percentage of the average tracks over a period of time to trigger the reopening.

I get system generated map problems all the time for closed roads. The problem is that waze will use old GPS data to create new map problems. I am entirely convinced that this is a waze problem, not an issue with construction workers keeping waze on in construction zones.

Yes, even after multiple promises from Waze about the GPS points being more up to date in WME (USA/Canada) they continue to appear to be out of date. In addition the map problems also appear to reference out of date GPS track data.

In addition, these map problems even when marked "not identified" seem to attract the attention of ign and level(6) editors, resulting in edits to recently realigned roads in new constructions zones made by those not familiar with the area based on old gps data and outdated aerials.

Ah, that makes more sense. I couldn't figure why I kept getting those error reports from waze.

I've noticed that occasionally, for whatever reason, the MP analysis is run with old (9+ months) GPS traces, this might be what you're seeing there.

Some GPS programs have an option to report "road blocked ahead", this can be used if a road is actually blocked or if you are in traffic and want an alternate route. Perhaps this is the only feature Waze would have to implement.

Another feature would be after a few "blocks" are reported at the same point, a warning could be sent to Area Managers of that region.

Yesterday Waze routed me trough flooded road in the middle of country lane, not only had to 'manually' find detour by myself, I couldn't use Waze anymore as it constantly was giving me direction to the same place, not reporting nor alternative routes helped. I think, if I make road closed the Waze for me will not use it for the period of time. Other users will have a prompt like: Proposed route includes road reported as closed. Alternative routes ... Select desire route. And user could decide whichever to try closed road or not.
