[sumo-user] Units of lcStrategic, lcLookaheadLeft, lcAssertive, lcSpeedGain

[Soumya Sharma via sumo-user]

Hello,
I am trying to conduct a sensitivity analysis of car-following and
lane-changing parameters in SUMO for hypothetical freeway segments (basic
and weaving). I tried changing headway values (car-following) and
lcStrategic values (lane-changing) for a basic segment. I used lcStrategic
values of 500, 1000, and 1500 for trucks in simulations (length = 15.25m).
My trucks are using the CACC model.
The two metrics I am interested in are the travel rates (secs/ mi) by
vehicle type and the number of lane changes per vehicle type. I found that
there was no change in travel rate and a number of lane changes when I
changed the value of lcStrategic to 500, 1000, and 1500. I don't understand
why there was no effect of changing the parameter values.
Next, I want to look into other parameters like "lcLookaheadLeft",
"lcAssertive" and "lcSpeedGain".

*Question*: I would like to understand the units of the parameters
"lcStrategic" and "lcLookaheadLeft", "lcAssertive" and "lcSpeedGain".

The SUMO documentation says:

   1. lcStrategic: The eagerness for performing strategic lane changing.
   Higher values result in earlier lane-changing. default: 1.0, range [0-inf),
   -1 A value of 0 sets the lookahead-distance to 0 (vehicles can still
   change at the end of their lane) whereas -1 disables strategic changing
   completely.
   2. lcLookaheadLeft: Factor for configuring the strategic lookahead
   distance when a change to the left is necessary (relative to right
   lookahead). default: 2.0, range [0-inf)
   3. lcAssertive: Willingness to accept lower front and rear gaps on the
   target lane. The required gap is divided by this value. default: 1, range:
   positive reals
   4. lcSpeedGain: The eagerness for performing lane changing to gain
   speed. Higher values result in more lane-changing. default: 1.0, range
   [0-inf)

These definitions don't mention any units explicitly, are they all factors?
i.e. unitless or are some of them in meters and some unitless?

I was checking the code
for
LC2013 and found that look ahead distance (laDist) is being calculated as
follows:

laDist = myLookAheadSpeed * LOOK_FORWARD * myStrategicParam * (right ? 1 :
myLookaheadLeft);


If this is how the look-ahead distance for a vehicle is calculated when
making lane-changing decisions, then both lcLookaheadLeft and lcStrategic
specified will be used to calculate laDist but I don't know what what the
units of any of these parameters are. For laDist to be in distance units,
speed would be multiplied by time here.

Please share any information that is available as it would help me
understand my results better.

Thanks,
Soumya.

Re: [sumo-user] deactivate rerouting of vehicle

[Jakob Erdmann]

You can use setParameter(vehID, "device.rerouting.period", "0") to disable
period rerouting.

[sumo-user] deactivate rerouting of vehicle

[manos kampitakis]

Hi all,

Is there a way to deactivate a vehicle from rerouting? For example, I want
vehicles to reroute each 5 mins only if they are placed in a certain area
of my network. I tried to set the parameter "has.rerouting.devise" to
"false" but threw an error: "Device removal is not supported for device of
type 'rerouting' ". Is there another way to bypass this? Also, I think that
it would be good to include this in a later version. Thanks in advance.

Best regards,
Manos

Re: [sumo-user] Unable to generate vehicles in osmWebWizard

[Jakob Erdmann]

Quite strange! Below is what I would expect the command line window for
webwizard took like:

[image: grafik.png]


any errors that would cause "recovering" in the webbrowser should be listed
here.

Please try calling
python "%sumo_home%\tools\osmWebWizard.py" 2>&1 > wizardlog.txt

and then check the contents of wizardlog.txt

Re: [sumo-user] Taxistands

[Jakob Erdmann]

- solution 1: traci.vehicle.getStopParameter(vehID, 0, 'started')  (you can
check whether the vehicle is currenlty stopped with vehicle.getStops
- solution 2: track the time at which vehicles entered the taxistand with
traci.simulation.getParkingStartingVehiclesIDList (then record the time and
vehicleID yourself for later reference).
