The idea behind this output option is to detect the queue in front of the controlled/uncontrolled junction. The queue length is calculated using the end of the last standing vehicle.
Instantiating within the Simulation#
The simulation is forced to generate this output using the option --queue-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.
The generated XML file looks like this:
<queue-export> <data timestep="<TIME_STEP>"> <lanes> <lane id="<LANE_ID>" queueing_time="<LANE_QUEUEING_TIME>" queueing_length="<LANE_QUEUEING_LENGTH>" queueing_length_experimental="<LANE_QUEUEING_LENGTH_EXPERIMENTAL>"/> ... next lane ... </lanes> </data> ... next timestep ... </queue-export>
|time_step||(simulation) seconds||The time step described by the values within this timestep-element|
|id||id||The id of the lane|
|queueing_time||seconds||The total waiting time of vehicles due to a queue|
|queueing_length||meters||Thus the length from the junction until the final vehicle in line|
|queueing_length_experimental||meters||The length of the queue, thus until the last vehicle with a speed lower than 5 km/h|
This output option should offer some information about the queues in front of the junctions, which can be used in cases of routing or V2X communications.
