How can I calculate the dynamic travel time on a route?

This forum deals with any kind of routing computation whether it is simple A:B-routing, calculation of isochrones, simple matrix computation or nearest search.

How can I calculate the dynamic travel time on a route?

Post by Judith Straub »

Hi,

We use xroute to calculate routes including the PTV_TrafficIncidents. Usually the xRoute searches the fastest path and therefore performs a detour if a traffic incident is on the standard route.

What we need is this:
Is it possible to determine the time that is required on the standard route even if we have to slow down or wait due to a traffic jam?
If it is possible: how does it work then?

Best regards
Judith

Hello Judith,

sounds lkike you need to apply the DynamicTimeOnStaticRoute mechamism:
Here is s sample snippet for xRoute 1:

Code: Select all

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Profile parent="truckfast" xmlns:ns2="http://www.ptv.de/com/ptvag/xserver/engines/xpoidbaccess">
    <FeatureLayer majorVersion='1' minorVersion='0'>
<GlobalSettings enableTimeDependency="true" enableVehicleDependency="true"/>
      <Themes>
          <Theme id='PTV_TrafficIncidents' enabled='true'/>
      </Themes>
    </FeatureLayer>
    <Routing majorVersion="2" minorVersion="0">
     <Course>
      <AdditionalDataRules enabled='true'/>
     <DynamicRouting dynamicTimeOnStaticRoute="true" layerName="PTV_TrafficIncidents" 
     limitDynamicSpeedToStaticSpeed="true" useFreeFlowSpeed="false"
     useLegacyDynamic="false">
     </DynamicRouting>
     </Course>
    </Routing>
</Profile>
left: standard route, determined without TrafficIncidents (569km / 6h35m)<br />Middle: dynamic route performing a detour around the traffic South of Hannover (570km / 8h30m) <br />Right: standard route geometry with dynamic time: longer driving period due to jam (569km / 12h15m)<br /><br />So the path of the left and the right route are equal but the driving times differ.

So the path of the left and the right route are equal but the driving times differ.
Does this answer the question?
