Re: [sumo-user] Beginner for SUMO
Hello,
teleporting is usually done to mitigate scenario problems. Raising this value can be useful it the scenario is intentionally jammed and vehicles should be forced to stand around rather than teleport to resolve deadlocks.
Teleporting can also be used to model the fact that vehicles typically find a way around blockages in ways that is not explicitly handled by the simulation (e.g. driving over curbs and sidewalks).
If you want to model the jamming that occurs due to the accident then you could use a higher value for time-to-teleport in the accident. But this also depends on your assumptions on whether vehicles can find a way around the blockage or not.

regards,
Jakob

teleporting are usually an indicator of scenario problems and
- when there are problems with the scenario
- when you are modell

Dear, 

In my case,I create an accident by stopping the vehicle for 10 minutes. I use '--time-to-teleport',"650" for both with accident case and without accident case. Is it consistent?  Can  effect of this parameter may be different or not for two cases? Could you tell me some suggestions? 

Thank you in advance. 

with best regards,

Dear, 

Now, I can create the accident case by stopping the vehicle. Thank you very much. Another I would like to know is that I want to get the data by using traci in every minute not every second. Can I use the --step-length? Could you give me some suggestion? 

with best regards,

Noted. I will try again. Thank you for your reply.

Right-click the stopping vehicle in sumo-gui and select 'show current route'. This will cause stop duration info to be shown in the GUI. Is the duration value correct? Does it decrease as expected? What happens after the time is up?

Dear, 

Vehicle always stop on the specified lane even duration is over.

What are the symptoms of "not working"?

Dear, 
Thank you for your time. 
Now I use sumo 1.0.0 version. When I try to create accident case as the following:
if(step>=21600 and step<=22000):
      traci.vehicle.setStop('43.0',edgeID='L10189',laneIndex=1,pos=90,duration=600,flags=0,startPos=50);
duration is not still working. Something wrong in my code? 

with best regards,

Answers below:

Now I would like to know about the difference between the outputs of edge-based measures and using lane area detectors. I want to get the information related with edge like density, occupancy , speed.  For this purpose, which of the following approaches is suitable? 

1) edge-based measures
2)using lane-area detectors 

The main difference is that edge based measures always count the whole edge whereas detectors only count a lane section.
Both approaches are possible but edge based measures require less aggregation if you need the data for the whole edge.
 

traci.vehicle.setStop('43.0',edgeID='L10189',laneIndex=1,pos=90,duration=600,flags=0,startPos=50);
but in this case, duration attribute is not working.
In older versions of SUMO, setStop requires a duration in milliseconds. since 1.0.0 duration is in seconds.
 

In my case, I want queue length of each edge. For this case, now I compute the average value from queue length of each lane by using lane area detector. Is it possible by using this way? Or are there any other methods to get queue length directly from each edge? 

No, the queue length is only available for each lane. You have to aggregate the edge data yourself.

regards,
Jakob
