Re: [sumo-user] Problem with converting vissim to sumo.

2017-09-26 Thread Jakob Erdmann via sumo-user 
Somewhere in your inpx file is an xml attribute with an empty value
(someAttribute=""). This is not expected by the importer.
Search for "" in your file and try to remove the attribute (or set an
appropriate value).

Jakob

Re: [sumo-user] Simulation Step TraCI call at time 0

2017-09-26 Thread Jakob Erdmann via sumo-user 
Hello,
when you take a look at the gui, you will find that the first call of
simulationStep(0) advances the simulation to the end of step 0 (with
vehicles departing at 0 already being inserted).
Only the command simulation.getCurrentTime() already shows you 0.5 because
all further traci calls will be processed at the start of the step that
ends at 0.5
However, any vehicle positions you retrieve after the first call to
simulationStep will be the ones from the insertion step 0.
regards,
Jakob

[sumo-user] Time step right before arrival

2017-09-26 Thread Mani Amoozadeh via sumo-user 
Hello,

 

Is there any ways to figure out the last time step before vehicle's arrival
?

I want to call a TraCI function on a vehicle right before its arrival.

 

Thanks!

[sumo-user] Simulation Step TraCI call at time 0

2017-09-26 Thread Mani Amoozadeh via sumo-user 
Hello,

 

I setup a SUMO simulation with 0.5s time step in TraCI mode.

Once the TraCI is established I subscribe to departed vehicles count and
then insert 10 vehicles at time 0s.

I call simulation step like this:

 

simulationStep(500) --> simulationStep(1000) --> simulationStep(1500) .

 

The first simulationStep returns subscription result that all 10 vehicles
have departed.

 

Is there any way to call simulationStep like this:

 

simulationStep(0)  --> simulationStep(500) --> simulationStep(1000) -->
simulationStep(1500) .

 

So that the first simulationStep call give me the subscription result
showing that all vehicles have departed.

Apparently, I cannot do this since 0 has a special meaning and proceeds
simulation to 500ms.

Is there any workaround for this?

 

Thank you.

 

- Mani

[sumo-user] Overtaking issue when switching to sublane model

2017-09-26 Thread alex goupilleau via sumo-user 
Hello all,


In order to create scenarios with Traci where I can control the longitudinal 
position of the vehicle, I switched from the default lane-changing model to the 
SL2015 model.

I have a simple network composed of two edges side by side in opposite driving 
direction. Each edge only has one lane.

I created a scenario with this network where I have two vehicles on the same 
edge, and I set the speed of the following one so that it overtakes the first 
one.

With the LC2013 default model, the vehicle overtakes (makes a lane change to 
the other edge), and with the SL2015 (only adding the option --lane-resolution, 
nothing other than that is different), it does not overtake anymore.


Would you know why ?


Thanks,


Alex
