Special FeatureLayer : Genovese bridge incident

Postby Bernd Welter » Fri Sep 07, 2018 3:18 pm

Hi there,

as we all know the Ponte Morandi (=Morandi Bridge = Morandi Brücke) in Genovese (Genova / Genua) collapsed in August 2018. Due to the incident several roads cannot be used and some players asked us whether we can handle this topic and it's derived consequences with xRoute and xMap server.

  • short term (2018.1/2018.2 maps): Our data department produced a special Feature Layer that contains several blockings of the affected streets.
  • mid term (2019.1 maps): The next map versions will simply block the bridge itself (not the underlying streets) via map data (instead of FeatureLayer). Schedules: 2019.1H=end of october 2018, 2019.1T=end of november 2018.
  • Important to know: The special feature layer files do not replace the regular ones - they have to be added to the core layers.

By applying the additional data you can compute detours around the are of the incident.

On the left side: a route that avoids the critical segments by applying the PTV_TruckAttributes layer
On the right side: a route that uses critical segments and raises violations.

Please get in touch with your technical counterpart at PTV to get further info about the special layer.

Best regards,
Bernd

Hi there,

in the meantime I received further info about the approach. We can offer two different feature layers.

  • Both layers apply specific restrictions to the collapsed road and the underlying streets (the set of segments is equal, only the attributes vary)
  • You need proper license keys to benefit from the layers
  • There is a FeatureLayer file (*.flr) which should be copied in the featurelayer folder in the map directory.
  • You can activate the layers via profile snippets or server profiles
LayerPTV_TrafficIncidentsPTV_TruckAttributes
AttributesAll segments are blocked based on speed reduction: absoluteSpeed (km/h) = 0All Segments are blocked for all trucks (vehicle with load type Goods and totalPermittedWeight > 3.5 tons
ImportantEven if you allow violations the segments won't be used as they will not produce optimal ways.You can enable violations. You can't distinguish regular truck attributes from the special ones. Only applies to trucks, so regular cars won't be affected.
In xroute and xmap the FeatureLayer Theme has to be activated<Theme id="PTV_TrafficIncidents" enabled="true"/><Theme id="PTV_TruckAttributes" enabled="true"/>

And here's a minimal snippet (for PTV_TrafficIncidents, just replace by PTV_TruckAttributes):
xml code
<?xml version="1.0" encoding="UTF-8"?>
<Profile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http:///xroute/schema/XRouteProfile.xsd">
<Routing majorVersion="2" minorVersion="0">
<Course>
<AdditionalDataRules enabled="true" layerName=""/>
</Course>
</Routing>
<FeatureLayer majorVersion="1" minorVersion="0">
<GlobalSettings enableTimeDependency="true"/>
<Themes>
<Theme id="PTV_TrafficIncidents" enabled="true"/>
</Themes>
</FeatureLayer>
</Profile>


So much for now,
Bernd
