Re: [sumo-user] problem about meso-simulation

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

You can use meso to test traffic light algorithms (by setting option --meso-junction-control) but the dynamics (in particular acceleration and time on junction) will be much coarser.

The warning pertains to this: https://sumo.dlr.de/docs/Simulation/Intersections.html#internal_links

For testing small to medium size scenarios of traffic light control I would recommend micro (the default) over meso.

Jakob

Dear all, 

I have tried to use the option in my simulation.

<Mesoscopic>  
     <mesosim  value="true"/>
    </Mesoscopic>

  The command window printed some information. 

There is one information printed as "vehicles will jump over junctions".

What does it mean?

If I was going to use Traci to modify the program of traffic lights to control the traffic flow, does it mean that the user-defined program could not have an effect on the traffic flow? 

Could someone help me to explain how to deal with this problem? In other words, could I modify the traffic lights program during meso-simulation by Traci?

Best regards,

Jane Chueng
