Re: [sumo-user] Charging data using TraCI subscriptions

[Padisala, Shanthan Kumar]

*** Clarification to my previous question ***

I am currently using the command - traci.vehicle.getParameter('Vehicle', 
'device.battery.actualBatteryCapacity')  to get the information on the battery 
capacity at the current time step. However, I would like to use TraCI 
subscriptions for the same task.

I understand that using TraCI subscriptions I can get data of the vehicle like  
speed using the commands - traci.vehicle.subscribe('Vehicle', (tc.VAR_ROAD_ID)) 
and traci.vehicle.getSubscriptionResults('Vehicle'). So now basically I would 
like to use the same logic to get data from a device- battery.

Thank you,
PSK

Subject: Charging data using TraCI subscriptions

Dear Jakob,

Greetings!

I am trying to use subscriptions to get the charging data (energy input or any 
other relevant data) of an electric vehicle when it is being charged at the 
charging station. But I am unable to figure out the TraCI subscription commands 
that are used to do this. Could you kindly help me out with this?

Re: [sumo-user] The definition of time loss in tripinfo output

[Jakob Erdmann]

The formula I wrote corresponds to the value of v_max in Michaels formula
(to explain that your change in driving speed triggers timeLoss whenever
your set v differs from v_max).

[Radha Reddy]

But for me Michael sent the following formulation. Now I am confused.

Hi,
the time loss in a single time step is calculated as
 step_length * (1 - v / v_max)
where v_max takes into account the speedFactor, maxSpeed on the lane and
the vType. For a time interval it is simply summed up.

Best regards,

[sumo-user] help

[NaolyTech]

Dear my friends, how are you doing? I really miss you. Thank you for your
kindly response really.

In my vanet simulation work, i confused on the following things to go
forward:
   But before that:
1) I created highway road of 2500 length with two direction with 4
lanes per   direction.
2) I created the routes for 300 vehicles and some attributes
3) I created SUMO configuration file for two files above
4) Then I created SUMO trace file from .sumocfg file created above
using:
   "sumo -c name.sumocfg --fcd-output sumoTrace.xml"
5) Then I generated ns2mobility file using:
   "python traceExporter.py --fcd-input sumoTrace.xml
--ns2mobility-output mobility.tcl"

After all these work done, i stopped where to go because my targets are:
  1) applying BSM (Basic Safety Mesaage) application on the scenario i
created above highway road 2500m long with 300 vehicle above.

   2) storing produced vehicles bsm trace file in "anyName.csv file"  from
communication taken place among vehicles I created on the above scenarios.

 ..So how can make these all
???..
I hope you have got my idea and help me on these points.

Thank you
Naol

Thank you so much Jakob.

If I want to run the command *"traci.vehicle.getLeader(vehID, 1000)"* in

How may I know what template for VEINS to use?
It is a bit confusing.

The getLeader function limits it's lookahead range to the braking distance
by default. You could try calling traci.vehicle.getLeader(vehID, 1000)

 Hi,

 I am trying to take complete control of vehicle speed acceleration
 ..etc.
 But whenever I define vehicles using  tags in routes
 and run the simulation, it will be automatically assigned with Car
 Following Model and LCModel.
 These models will control the vehicle using the defined algorithm.

 Is it possible to define vehicles with no control from simulator?
 If yes, then how to do so please?

Re: [sumo-user] RouteSampler.py demand generation problems

[Jakob Erdmann]

routeSampler only uses the routes that you already provide as input. Of
course, you can use implausibleRoutes.py before running routeSampler to
analyze and tailor the input.

Looking at your scenario, I see the following issues
- uncoordinated/unjoined traffic light in the city center
- missing acceleration lanes at your motorway on-ramps. This turns highway
on-ramps into normal junctions and reduces flow significantly.  (add ramps
manually or rebuild your network with option --ramps.guess. This may split
some edge which invalidates routes so afterwards you will have to
regenerated your route files or repair them with duarouter option --repair

regards,
Jakob

Re: [sumo-user] fundamental diagram

[Jakob Erdmann]

1) can you post your VSS definition?
2) Since density is increased by vehicle insertions which are discrete
events there is some limit to the achievable smoothness. You could "cheat"
by using more VSS though.

Re: [sumo-user] fcd output and time step accuracy

[Jakob Erdmann]

A main source of differences between simulations with different step
lengths is vehicle insertion (more frequent insertion attempts lead to
higher insertion flow). See
https://sumo.dlr.de/docs/Simulation/VehicleInsertion.html

To achieve vehicle behavior closer to the 1-second simulation, run the
simulation with --step-length 0.1 --action-step-length 1
Make sure that all vehicles depart at full seconds or this will be another
source for scenario divergence.

Re: [sumo-user] Modeling of speed, congestion and flow in SUMO

[Jakob Erdmann]

The default microscopic model does not compute congestion. Instead,
congestion is an emergent feature of individual vehicle behavior (i.e.
slowing down for leading cars).

Re: [sumo-user] Braking for turns

[Jakob Erdmann]

The cars brake ahead of the turn so that they reach the slower section at
the permitted speed (it works the same for regular speed limits).

Re: [sumo-user] setSpeed acceleration/deceleration

[Jakob Erdmann]

At the moment, most models use uniform acceleration when setSpeed is
called. The only exceptions are carFollowModel "rail" and "KraussPS" which
have degressive acceleration at higher speeds.
There are plans to make this more flexible:

Re: [sumo-user] Traffic simulation for a month

[Jakob Erdmann]

The differences are up to you. By providing different route files for the
different days (i.e. less traffic on weekends) you have full control over
the variability. SUMO itself will not perform replanning based on past
experiences. Unless you have jams that are not resolved during the night,
each simulated day should be pretty much independent of the previous day
(though you will see different random numbers when running the simulation
for multiple days compared to running these days separately).

[sumo-user] TraCI slowDown function

[Proyash Podder]

Hi!
I was trying to play with TraCI’s slowDown API and facing an issue. For my 
simulation, say, I need to reduce my speed to 2 unit. So, I write this: 
traci.slowDown(speed-2,1).

But the result I got is: If at 5.00 Second, the speed is 20, at 6.00 second, I 
see the speed to be 19 and at 7.00 second, I see the speed to be 18.. But 
theoretically, the speed should become 18 at 6.00 second.

One case might be if the max deceleration rate is low so that it cannot reduce 
the speed so fast. But then, I rewrite the slowDown function to that: 
raci.slowDown(speed-4,1).  Now I see that, at 6.00 second, I got the speed 18 
and the speed become 16 at 7.00.

So, in summary although I try to reduce the speed by x unit at 1 second, it 
takes 2 seconds to make so.
Can anyone explain to me, what I am getting wrong here?

Re: [sumo-user] Rerouting in SUMO using TraCI

[Jakob Erdmann]

1) most likely, no vehicle ever reaches a waiting time of 600s. By default
vehicles are teleported after being jammed for 300s
2) the difference is in the way travel times are estimated. The rerouting
device averages speeds (and thus travel times) over time with a
configurable algorithm. In contrast, rerouteTraveltime uses current travel
times by default and is therefore more sensitive to short-lived
fluctuations (i.e. from traffic lights).
