How to apply PTV_TruckAttributes (xRoute2)

[Bernd Welter]

Quite often users approach us with an issue such as

I am calculating a route for a large truck but the route takes a path that is forbidden for this kind of vehicle - what are we doing wrong?

blue route: "wrong" route which uses a tunnel with a height restriction (2.60m). By applying the TruckAttributes properly the "correct" green route is returned.

Well, the cause for this "experience" is quite simple - here's the xServer2 response:
To consider the so-called truck attributes data properly you need to provide two ingredients:

• Proper releant attributes of the vehicle, either via a reference to a storedProfile (e.g. "truck40t") or through a requestProfile
• Request the consideration of the additional data such as the PTV_TruckAttributes through a so-called feature layer theme.

The second part is often overseen and quite simple to be resolved. And of course you could also request several additional data sources at a time, e.g.

• PTV_TruckAttributes
• PTV_RestrictionZones
• PTV_PreferredRoutes (and more)

Here's an overview of the available layers.

Here's a sample request:

Code: Select all

  "storedProfile":"truck40t",
  "requestProfile":{
    "featureLayerProfile":{
      "themes":[
        {
          "id":"PTV_TruckAttributes",
          "enabled":true          
        }
      ]
    }
  },
