Simulation/Output/VehRoutes

generated on 2019-05-24 00:19:29.046180 from the wiki page for Simulation/Output/VehRoutes for SUMO git

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>

Name Type Description
id (vehicle) id The id of the vehicle this entry describes
type vehicle type id The id of the vehicle type if different from the default
depart s The time the vehicle was emitted into the network
arrival s The time the vehicle was removed from the simulation (due to arriving at the route end)
routeLength m The total length of the vehicle's route (if activated by the vehroutes.route-length option)
replacedOnEdge (edge) id The edge the vehicle was on when the described route was replaced
replacedAtTime s The time step of this replacement
<PREVIOUS_ROUTE> [(edge) id]+ The replaced route
<LAST_ROUTE> [(edge) id]+ The final vehicle route
<EXIT_TIMES> [time in s]+ The leave time for every edge in the route, if enabled with the option --vehroute-output.exit-times
Note:
Additional attributes of the vehicle are also included if they were set.

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.
