• VehRoutes

The vehicle routes output contains information about which route a vehicle took and if his route was replaced at any time by a new one, each of the previous routes together with the edge at the time their replacement took place is reported. Furthermore, the times the vehicle has entered and has left the network are stored herein.

In normal conditions, when all vehicles use predefined routes, the output does not contain any information that could not be retrieved from the routes and the tripinfo output. But as soon as you reroute your vehicles within the simulation, f.e. using rerouters, it will contain new information.

Instantiating within the Simulation#

This output is enabled for a simulation using the option --vehroute-output <FILE> or --vehroutes <FILE>. Further options affecting this output are listed at SUMO#Output.

Generated Output#

The generated file look like this:

<routes>
    <vehicle id="<VEHICLE_ID>" [type="<TYPE_ID>"] depart="<INSERTION_TIME>" arrival="<ARRIVAL_TIME>" [routeLength="<LENGTH>"]>
        <routeDistribution>
            <route replacedOnEdge="<EDGE_ID>" replacedAtTime="<TIME>" probability="0" edges="<PREVIOUS_ROUTE>"/>

            ... further replaced routes ...

            <route edges="<LAST_ROUTE>" [exitTimes="<EXIT_TIMES>"]/>
        <routeDistribution>
    </vehicle>

    <person id="<PERSON_ID>" depart="<INSERTION_TIME>" arrival="<ARRIVAL_TIME>">
        <ride from="..." to="..." lines="..." [started="<START_TIME>" ended="<END_TIME>"]/>
        <walk edges="..." speed="..." [exitTimes="<EXIT_TIMES>" started="<START_TIME>" ended="<END_TIME>"]/>
    </person>

    ... information about further vehicles and persons ...

</routes>

Both the previous and the final routes are complete, that means that they contain all the edges the vehicle was meant to pass as long as the route was not replaced, yet. The information replacedOnEdge and replacedAtTime are available only for routes which were replaced. The probability field is only given to make the file directly usable as input to the simulation which lets the vehicle travel its final route. For proper simulation input the file should be also sorted by departure time. This can be accomplished by also setting option --vehroute-output.sorted.

Output only for selected vehicles or vehicle types#

By default all vehicles will generate vehroute-output. By assigning a vehroute device to selected vehicles or vehicle types, this can be changed. As an example, the following definition enables the device for the vehicle type t1:

<vType id="t1">
  <param key="has.vehroute.device" value="true"/>
</vType>

Alternatively, you can use the SUMO option --device.vehroute.probability to set the probability for a vehicle to generate the vehroute-output. For example, setting the option --device.vehroute.probability 0.25 will equip about a quarter of the vehicles with a vehroute device (each vehicle determines this randomly with 25% probability).

Further Options#

• --personroute-output FILE: Writes output for persons/containers to a separate FILE
• --vehroute-output.exit-times: Write the exit times for all edges, the attributes 'started' and 'ended' for stops and include attribute 'ended' for rides.
• --vehroute-output.last-route: Only write the final route (if the vehicle was rerouted during the simulation)
• --vehroute-output.sorted: Sorts the written vehicles by departure time
• --vehroute-output.dua: Write the output in the duarouter-alternatives format
• --vehroute-output.cost: Write attribute 'cost' for all routes
• --vehroute-output.intended-depart: Use the intended departure time rather than the actual departure time (in case of departure delays)
• --vehroute-output.route-length: Write total route length as attribute 'length'
• --vehroute-output.write-unfinished: Write vehroute output for vehicles and persons which have not reached their destination at the end of the simulation
• --vehroute-output.skip-ptlines: Skip vehroute output for public transport vehicles (vehicles that have a 'line' attribute)
• --vehroute-output.incomplete: Include invalid routes and route stubs (from-to) in the vehroute output
• --vehroute-output.stop-edges: Include information about edges between stops
• --vehroute-output.speedfactor: Include information vehicle specific speedFactor in output (defaults to 'true' if the vehicle had its departSpeed set)
• --vehroute-output.internal: Include internal edges in the output. Note, that such routes are not suitable for being loaded by sumo or duarouter!
