How to block roads in winter (mountain passes)?

[Bernd Welter]

Here's a little description how to block special roads such as mountain passes in wintertime.

xServer 1 - profile based

• also mentioned in this article by Joost
• Based on boolean segment attribute "blockedInWinter"
• XML profile offers an attribute parameter blockedInWinterMalus
• Advantage: Compareably easy, built-in visualization is possible (render profile supports parameters)
• Disadvantage: you rely on the data - if a specific object such as a mountain pass isn't properly set in the data you can't use it.

xServer 2 - manual efforts required

• As of today (August 2022) the routing API in the xServer 2 does not access the data properties.
• You have to specify the relevant segments on your own via features such as Custom Feature Layer (on premise only) or GeographicRestrictions.prohibitedSegmentsByIntersectingPolylines
• Advantage: more flexible - if you maintain the geomentries manually you can also add attributes such as "blocked from" and "blocked till" dates. Furthermore you can easily visualize the data - it is yours.
• Disadvantage: you rely on the rough geometries you have picked.

The screenshots below use the GeographicRestriction. I manually gathered geographies at the entrance of the passes. the blue pins show the position of the "blockings"

Feel free to provide further relevant sections. Thanks to Beat for the trigger

Just found this image based on 2018 TOMTOM data Nice coverage!

The routing from Bormio to Zernez. As there are time dependent PTV_TruckAttributes the time consideration has an impact on the geometry. I calculated the routes for 29.7.2024 and 29.01.2024 (windter - blocked)
