Hey Jakob,

I prepared the traffic counts, created some routes for a small test area and it 
seems to work fine, thanks!

I want to expand the simulation to a whole city and therefore need to create a 
lot of random routes. Can I somehow determine an appropriate number of random 
routes or do I need to use my gut feeling and test it?

Best regards
Simon

Since you're using calibrators, I assume that you already know the desired 
amount of traffic in many places. In this case, you could also build your 
scenario with routeSampler:

Hey Jakob,

thanks for the hint. This actually showed me that the issue is somewhere else 
and just causes the same symptoms as long calibration intervals.

The problem is the amount of traffic inserted by random trips and the 
calibrators. Is there any other way to find the right amount of traffic 
inserted into a macroscopic simulation other than try and error?

Thanks and best regards
Simon

I misread your flow definition so ignore my prior comment.
Please check if there are delayed insertions on the calibrator edge 
(https://sumo.dlr.de/docs/Simulation/VehicleInsertion.html#investigating_insertion_delay<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsumo.dlr.de%2Fdocs%2FSimulation%2FVehicleInsertion.html%23investigating_insertion_delay&data=02%7C01%7Csimon.frentrup%40umlaut.com%7C908173a18e404f31395a08d83ddb85e9%7C58d65043cd9d409f828b59b40ef5f919%7C0%7C0%7C637327360345907205&sdata=%2FWki3nOqezpPUZ6CnlZIpcadrSGybVthWtclAKDHu1U%3D&reserved=0>).
 If that is not the case, send in your input files so I can take a look.

Hey Jakob,

thanks for your reply.

Where do I exactly have to add the end-attribute? In the flows it’s already 
present, just not directly after the begin-attribute.

Best regards
Simon

You need to define the 'end' attribute of the calibrator flows explicitly.

Jakob

Hey guys,

I’m currently running a simulation for one hour with calibrators, but they 
don’t behave as they should. The file with the calibrator definitions looks 
like this:

<?xml version="1.0" ?>
<additional 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance<https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchema-instance&data=02%7C01%7Csimon.frentrup%40umlaut.com%7C908173a18e404f31395a08d83ddb85e9%7C58d65043cd9d409f828b59b40ef5f919%7C0%7C0%7C637327360345917155&sdata=kh%2Bj5Q12C5932ask4qSp2osOLTtY1QfSoAS8v%2F1QB8c%3D&reserved=0>"

…
<inductionLoop file="inductionLoop.xml" freq="10" 
id="inductionLoop_-26953591#1_0" lane="-26953591#1_0" pos="-1"/>
…
<calibrator edge="-26953591#1" id="cali_-26953591#1" pos="1" 
routeProbe="routeProbe_-26953591#1">
        <route edges="-26953591#1" id="cali_-26953591#1"/>
        <flow begin="53" departPos="free" departSpeed="max" end="112" 
route="cali_-26953591#1" type="private" vehsPerHour="55.576395141497045"/>
<flow begin="113" departPos="free" departSpeed="max" end="172" 
route="cali_-26953591#1" type="private" vehsPerHour="55.08124042362967"/>
        …
</calibrator>
</additional>

All calibration intervals are set to 60 seconds, but what I get as a result 
from the variable interval_sampledSeconds in the induction loop file looks like 
this:

[cid:[email protected]]
The result looks like the calibration interval is for the complete hour and not 
for the defined intervals, which leads to a massive insertion of traffic and 
thereby to massive traffic jams.

Do you have any suggestions for me what I need to change in order to make it 
work in the intended way? Thanks in advance!

Best regards
Simon
