Dear, 

Thank you very much for your reply. 

Although I try, I cannot find vtype attribute in lane area detectors. How can I bind specific vtype and lane area detector? Thank you in advance. 

with best regards,

laneArea detector supports the attribute 'vTypes' for only recording types from the given list.

You can define separate detectors for each type to get the separate numbers.

Dear,

In my case, I would like to distinguish the type of vehicles that I got from using lane area detectors. Can we get separate number of vehicles from output file of lane area detectors? 

Thank you in advance.

Dear, 

In my case, I want to get the traffic light id and its state that control given lane id by using traci. Which traci function can I use? Could you suggest me? 

Thank you.

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.

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
