 ===== Kurviger Used a Road that is actually Not Accessible ===== ===== Kurviger Used a Road that is actually Not Accessible =====
  
-There can be multiple reasons for that. Here are the most common ones.+There can be multiple reasons for that. Basically there are two types of access restrictions,​ permanent restrictions and temporary or conditional restrictions. When asking a machine to calculate a route, permanent restrictions are easy, it's never allowed to use the road, so Kurviger won't create a route on this road. Temporary or conditional restrictions are a lot more complicated. For example a road is closed on Sundays, Kurviger cannot know if you would like to use this road on a Sunday or not. The Kurviger website allows you to show these potentially closed roads as an overlay, so you can include these in your planning.
  
-==== Construction Sites ====+==== Regular Permanent Access Restrictions ​====
  
-Construction sites are not always tagged ​in OSM. If the construction site is only a short-term construction site (less than 6 months), the general opinion is not to tag itIf the construction takes longer than 6 month, please go ahead and tag it[[https://​wiki.openstreetmap.org/​wiki/​Key:​construction|See ​the OSM wiki for more details]].+Especially for smaller roads, there might be a missing access restriction ​in OSM. You should check that the access ​tag is set correctlyAccess restrictions can be set to ways and nodesGenerally we recommend to tag the ways. Ways also include ferries, so if a ferry is not transporting motorcycles,​ this can be tagged ​for the way of the ferry.
  
-==== Regular Access Restrictions ====+If a road is closed for motorcycles you would tag it ''​motorcycle=no''​. If no motor vehicles are allowed on the road you would tag it ''​motor_vehicle=no''​. There are many different options, most are described in the [[https://​wiki.openstreetmap.org/​wiki/​Key:​access|OSM wiki]].

 +==== Temporary or Conditional ​Access ​Restrictions ==== 
 + 
 +These can include road closures on the weekend, in the winter, at night, or for a certain period of time. This also includes construction sites shorter than 6 months. Tagging conditional access restrictions,​ might look a bit complicated at first, but don't worry, it's not that complicated,​ we will show you a couple of the common examples and it should ​be easy to extend it for your specific case
 + 
 +Road that is closed for motorcycles on the weekend: ''​motorcycle:​conditional=no @ (Sa,Su,​PH)''​\\ 
 +Road that is closed for some time, like construction site: ''​motor_vehicle:​conditional=no @ (2018 May 22-2018 Oct 7)''​\\ 
 +Road that is closed every year, for example in winter:\\ 
 +The fast and generic option is to use ''​access:​conditional=no @ winter''​. For many roads there is no fixed date, usually ​the road will be closed with the first snow and opened once the snow as removed in spring, so tagging no @ winter is not the worst option, but there is no way to automatically evaluate this.\\ 
 +Some roads usually have close from a certain month to another month, so you could use ''​access:​conditional=no @ (Nov-Mar)''​ for roads that are usually close from November to March. 
 + 
 +There are many more examples in the [[https://​wiki.openstreetmap.org/​wiki/​Conditional_restrictions|OSM wiki]]. If you are uncertain, let us know in our forum, we are happy to assist you.
