Re: [sumo-user] Detecors coupled to traffic lights
Hello,
you have encountered a netedit bug (https://github.com/eclipse/sumo/issues/7275).
As a consolation, the network and detectors can be loaded into sumo / sumo-gui just fine.
regards,
Jakob

Hello,

 

I used generateTLSE2Detectors.py to generate E2 Detectors, which are coupled to a traffic light.

And acted according to the following description.

https://sumo.dlr.de/docs/Simulation/Output/Traffic_Lights.html#coupled_areal_detectors

 

Instantiating within the Simulation It is possible to add E2-detectors which are coupled to a traffic light. Then, the tls is used to determine the intervals (aggregation) time instead of giving a fixed aggregation time. In this case, output will be generated every time the traffic light switches. To use this feature set attribute tl="<TL_ID>" to the desired traffic light id instead off attribute <freq>: <e2Detector id="<ID>" lane="<LANE_ID>" pos="<POSITION_ON_LANE>" length="<DETECTOR_LENGTH>" tl="<TL_ID>" file="<OUTPUT_FILE>" [timeThreshold="<FLOAT>"] [speedThreshold="<FLOAT>"] [jamThreshold="<FLOAT>"]/>

The command I use looks like this:

 

py generateTLSE2Detectors.py -n network.net.xml --tl-coupled -o detectors.add.xml

 

I am able to create a file, which contains numerous detectors such as in this example:

 

<additional xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/additional_file.xsd"> <laneAreaDetector file="e2output.xml" tl="48889630" friendlyPos="x" id="e2det_-152098431#0_0" lane="-152098431#0_0" length="7.24" pos="0"/> </additional>

 

 

 

But when I try to load the additional detector file into the network I get the following Warning:

 

                Warning: Essential SUMOTime attribute 'freq' of e2Detector with ID 'e2det_-152098431#0_0' is missing; e2Detector cannot be created

 

As far as I understood „tl“ replaces the attribute „freq“, is hat correct?

Is there anything I did wrong?

 

I attached the network and the additional detector file.

 

 

Thank you for your help.

 

Regards,

Benedikt Kaubrügger
