For details, see https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html
and search for "jam-threshold" in the page (it is explained in multiple
contexts)
You can download example scenarios at

>> === Enhancements ===
>>
>> - Simulation

>>   - Added support for the HBEFA4 emission model with more than 800
>> emission classes.
>>   - Vehicles at longer planned stops now switch off their engine.
>>   - Automated engine start/stop can be modeled.
>>   - Actuated traffic lights can now react to downstream jamming
>>   - On-demand stopping of public transport vehicles is now possible
>>
>> - netedit
>>   - Traffic light mode now supports all phase attributes of NEMA and
>> actuated tlTypes and fully supports the NEMA controller
>>   - All attributes can now be reset to their default value by deleting
>> the attribute
>>   - Walkingareas are now shown and can be located by id.
>>   - Shift-click in demand-stop mode now sets parent element (i.e.
>> vehicle).
>>   - Create edge mode now visually previews whether a new junction will be
>> created or an existing junction will be re-used.
>>   - Added dialog for fixing / reporting network element problems.
>>   - Improved visualization of trips between junctions.
>>   - A custom color rainbow is now supported for all data elements.
>>   - Added tooltips on mouseover
>>
>> - tools
>>   - tls_csvSignalGroups now supports generating actuated traffic lights
>>   - osmWebWizard now provides a seamless satellite background
>>   - plotTrajectories.py: Now supports plotting by leaderGap
>>   - addStops2Routes.py: Added various options to randomize stop
>> assignment (i.e. to model random break-down of cars).
>>   - routeSampler.py: now supports option --write-flows poisson to
>> generate flows with poisson arrival pattern.
>>   - routeSampler.py: Can now load pedestrian walks as candidate routes.
>>   - randomTrips.py: Can now define a timeline of different demand levels.
>>   - randomTrips.py: Now supports option --insertion-rate to define demand
>> as vehicles-per-hour and option --insertion-density to define demand as
>> vehicles-per-hour-per-km.
>>
>> - sumo-gui: 3D-view now permits opening vehicle context menu via
>> right-click.
>> - netconvert: Now supports generating NEMA controllers.
>> - netgenerate: Added option --random.type to pick a random edge type from
>> all loaded types.
>>
>> === Bugfixes ===

>> - netconvert
>>   - Fixed invalid reduction in edge shape detail at very dense geometry.
>> (regression 1.12.0)
>>   - Fixed crash when loading OpenDRIVE road object validity record.
