Simulation/Output/FCDOutput
generated on 2015-09-02 00:02:07.908791 from the wiki page for Simulation/Output/FCDOutput for SUMO 0.24.0
The FCD (floating car data) export contains information about each vehicle where it is located in the network and the current velocity.
Instantiating within the Simulation
The simulation is forced to generate this output using the option --fcd-output <FILE>. <FILE> is the name of the file the output will be written to. Any other file with this name will be overwritten, the destination folder must exist.
Generated Output
The generated XML file looks like this:
<fcd-export>
<timestep time="<TIME_STEP>">
<vehicle id="<VEHICLE_ID>" x="<VEHICLE_POS_X>" y="<VEHICLE_POS_Y>" angle="<VEHICLE_ANGLE>" type="<VEHICLE_TYPE>"
speed="<VEHICLE_SPEED>"/>
... more vehicles ...
</timestep>
... next timestep ...
</fcd-export>
| Name | Type | Description |
|---|---|---|
| timestep | (simulation) seconds | The time step described by the values within this timestep-element |
| id | id | The id of the vehicle |
| type | id | The name of the vehicle type |
| speed | m/s | The speed of the vehicle |
| angle | degree | The angle of the vehicle |
| x | --- | The absolute X coordinate of the vehicle. The value depends on the given geographic projection |
| y | --- | The absolute Y coordinate of the vehicle. The value depends on the given geographic projection |
When the option --fcd-output.geo is set, the written (x,y)-coordinates will be the lon/lat geo-coordinates.
Further Options
- using the option --fcd-output.geo will toggle output coordinates to WGS84 (for geo-referenced networks)
- using the option --fcd-output.signals will add signal state information to the output
NOTES
In combination with the given geometry of the vehicles (shapes) you can build some nice animations, e.g NASA WorldWind or Google Earth.
