Re: [sumo-user] Speed-Exponent and Speed

[Jakob Erdmann via sumo-user]

The edge probability (for depart and arrivel) is multiplied by
edgeSpeed^speedExponent.
The default exponent is 0 so speed does not influence probability. with an
exponent of 1, edges with twice the speed are twice as likely to be sampled.

Jakob

Re: [sumo-user] Searching for existing method of get routes for vehicles first time.

[Jakob Erdmann via sumo-user]

When loading  elements, the list of edges is loaded from the XML
input.
When loading  elements, the route is computed via
MSBaseVehicle::reroute which calls the compute() method a router instance
(e.g. DijkstraRouter).

Re: [sumo-user] use State Plain Coordinates to move vehicle (MoveToXY)

[Jakob Erdmann via sumo-user]

The problem comes from an earlier step because the lon,lat values are
outside the network boundary to begin with (The network covers an area
around lon=-122,lat=37 whereas your lon,lat inputs are widely off the
mark).
It turns out that "CA State Plane NAD83 coordinate" is something differente
altogether from NAD83 (as I was assuming).
You therefore need to convert your values to lon,lat in WSG84 using a
separate projection before converting lon,lat into sumo network coordinates.
This can be done using the python proj library using the appropriate proj4
code (though I'm not sure which one exactly as there appear to be multiple
zones for CA)
see

http://spatialreference.org/ref/epsg/nad83-california-zone-3-ftus/
http://spatialreference.org/ref/epsg/nad83-california-zone-3-ftus/proj4/
proj = pyproj.Proj("+proj=lcc +lat_1=38.43
+lat_2=37.07 +lat_0=36.5 +lon_0=-120.5 +x_0=200.0001016

Re: [sumo-user] use State Plain Coordinates to move vehicle (MoveToXY)

[Jakob Erdmann via sumo-user]

when converting lon, lat to network coordinates, leave out the rawUTM=True.
moveToXY requires the shifted positions rather than raw UTM.

  x2, y2 = net.convertLonLat2XY(lon, lat)

Re: [sumo-user] use State Plain Coordinates to move vehicle (MoveToXY)

[Jakob Erdmann via sumo-user]

Hello,
the position conversion functions provided by traci and libsumo only
support the projection embedded in the .net.xml file. In case of an OSM
import this means it will always transform between meters and WGS84 lon,lat.

Since NAD83 and WGS84 are within 1m of each other, you could use
net.convertXY2LonLat(x_feet * 0,3048, y_feet * 0,3048, True)
(The third argument is for using raw UTM values instead adding the network
offset)

regards,
Jakob

Re: [sumo-user] Extraction of speed profile of one particular vehicle

[Jakob Erdmann via sumo-user]

in version 0.32.0 you can use grep (needs to be installed seperately for
window: http://gnuwin32.sourceforge.net/packages/grep.htm
   grep 'id="yourVehID"'

in the latest development version you can set option
  --fcd-output.explicit yourVehID
and the use
 --fcd-output instead of --netstate-dump
to get output only for the specified vehicle.

Re: [sumo-user] Loaded vs Departed Vehicles

[Jakob Erdmann via sumo-user]

the function simulation.getLoadedNumber and getLoadedIDList only refer to
vehicles that were loaded in the last time step (usually vehicles are
loaded in chunks of about 200s (configurable using option --route-steps).
This means some of the loaded vehicles are schedulare to depart in the
future but they are already known to the simulation. They exist in the
simulation until their arrival.
You can query some variables only for vehicles that have departed (e.g.
getSpeed() but some things like getTypeID() are possible for loaded
vehicles that have not yet departed)
getDepartedIDs only returns vehicles that have just departed in the last
steop and not those that have departed further in the past.

Re: [sumo-user] Fully Controlled Vehicle

[Jakob Erdmann via sumo-user]

Hello,
- you can set the angle argument for moveToXY to the TraciConstant
INVALID_DOUBLE_VALUE and then sumo will calculate an appropriate angle
- if you call moveToXY for the remote-controlled vehicles in every
simulation step, then sumo will not  teleport/remove them but still
recognize them as obstacles.

regards,
Jakob

Re: [sumo-user] Reduce length for allow attribute lane

[Jakob Erdmann via sumo-user]

Hello,
the proper solution is to split the edge because access permissions in SUMO
cannot change within a lane.
If you perform the split in netedit (right-click, 'split edge here') then
it should not affect the number of lanes.
If you only split the edges that are incoming to an intersection rather
than both ('split edges in both directions') then there will be no
turn-arounds.
Also, if you have some reason to split both edges then you can still delete
the turn-around connections in netedit.
The equivalent effect can also be achieved with xml input of split
definitions (all lanes after the split must be declared so that the lane
number does not change).

regards,
Jakob

Re: [sumo-user] With latest SUMO ver. preexisting net-files can't be loaded

[Jakob Erdmann via sumo-user]

Hello,
the error message is intended because an edge that references non-existent
nodes could lead to faulty simulation behavior.
In earlier version of SUMO, the node information was not used as the
network is completely defined by edges lanes and connections and thus the
check was omitted.
However, in the current version, pedestrian models as well as
junction-behavior models make use of the topology information encoded in
the node/edge graph.
The error message would also help uncovering invalid netconvert behavior
because networks of that kind should never be generated.
If the problematic network was generated by a recent version of netconvert,
please let me know.
If the network was generated by a custom process of yours, please read

Re: [sumo-user] Sumo and CarMaker

[Jakob Erdmann via sumo-user]

Hello,
this is possible insofar as sumo allows remote-control of vehicles and
retrieval of all vehicles states.
Couplings to other driving simulators (e.g. VTD) have been accomplished in
the past.
There is no publicly available middle-ware to couple CarMaker to sumo so
you will have to write this yourself.

Re: [sumo-user] Adding sidewalks using NETGENERATE and NETEDIT

[Jakob Erdmann via sumo-user]

1) you need to add the option --sidewalks.guess to enable guessing (the
min-speed option only configures the heuristic).
2) The length of the sidwalk is automatically adjusted after recomputing
geometries (F5) or saving the network. If the length is wrong after that,
please explain the problem in detail (with an anotated screenshot).

Re: [sumo-user] Wrong calculation of edge length

[Jakob Erdmann via sumo-user]

Hello,
you have created a network without internal lanes. In this case the the
edges are declared artificially longer to ensure correct travel times. (see
http://sumo.dlr.de/wiki/Simulation/Intersections#Internal_links) If you
remove the option --no-internal-links the network will be built as you have
described above.
Also, you can use netedit to declare any edge length you like.

Re: [sumo-user] Rerouting Question

[Jakob Erdmann via sumo-user]

Hello,
The function rerouteTravelTime use the time values from
edge.getTraveltime() and this is based on the average vehicle speed at that
time. (no smoothing of past fluctuations and no extrapolation into the
future).
Various smoothing options are available when using the rerouting device
(but also no extrapolation into the future):

Re: [sumo-user] start time of green phase

[Jakob Erdmann via sumo-user]

Hello,
each traffic light typically has multiple green phases.
Also, a 'phase' in sumo has a somewhat different meaning compared to
typical traffic engineering usage. See
http://sumo.dlr.de/wiki/Simulation/Traffic_Lights#.3Cphase.3E_Attributes
You will have to determine the index of the phase(s) that are of interest
to you and sum up the duration of preceding phases.

Jakob

Re: [sumo-user] Combining Edges Using NetConvert

[Jakob Erdmann via sumo-user]

Hello,
To join edges that have the same attributes and that do not have a "real"
intersection with multiple edges between them (so-called geometry-like
nodes), set the option
--geometry.remove
There is currently no option to automatically split edges to achieve a
maximum length.
To compare congestion values among edges it might be easier to normalize
the measure with the edge length rather than trying to enforce homogeneous
edge lengths.

Re: [sumo-user] Error in randomTrips.py -> Routes with Inclusionof'--trip-attributes'

[Jakob Erdmann via sumo-user]

Look carefully at your quotation marks. The ones around 'best' are more
curly than the one after --trip-attributes=.
These typographic quotation marks are often inserted by text processing
applications.
Most likely the xml parsing brakes on these non-standard quotation marks.

Re: [sumo-user] (SUMO) TraaS Dynamic Routing & Incomplete Routes

[Jakob Erdmann via sumo-user]

Change target fails if the new target cannot be reached from the current
position. This is unrelated to the activation of automatic routing.
Also, automatic routing can be activated for all vehicles by setting the
option --device.rerouting.probability 1

Re: [sumo-user] (SUMO) TraaS Dynamic Routing & Incomplete Routes

[Jakob Erdmann via sumo-user]

Hello,
- automatic routing is suitable if you just want vehicles to react to
changing road conditions (congestion). This causes them to periodically
check if there is a better route and then change the route but keep the
original destination
- if you need more influence on the timing or individual routing
preferences you can call traci.vehicle.rerouteTravelTime
- if you need to change the destination you can call
traci.vehicle.changeTarget
- for intermediate goals that must be visited you can define 'via' edge
using traci.vehicle.setVia
- if you want to compute fastest routes without affecting a vehicle you can
call simulation.findRoute

Jakob

Re: [sumo-user] Opening TraaS GUI

[Jakob Erdmann via sumo-user]

Hello,
I'm not sure what you mean by TraaS GUI.
You can either use TraaS for creating a webservice that your own code can
connect to our you can use it directly as a client library for accessing
sumo. Either way you have to write your own code that uses TraaS and there
is no gui besides the sumo-gui and anything you create yourself.

Re: [sumo-user] Meso Sumo

[Jakob Erdmann via sumo-user]

Hello,
By default there are no lanes in meso. By setting the option
--meso-multi-queue, lane-specific queues are only created whenever an edge
has multiple successor edges (this is meant to avoid left-turning vehicles
impeding straight-going vehicles, for example).
At an on-ramp (1 successor) all vehicles are put into a single queue but
this is not meant to represent lane usage (maximum throughput corresponds
to the total number of lanes).

best regards,
Jakob

Re: [sumo-user] TL Logic validation

[Jakob Erdmann via sumo-user]

Hello,
netconvert returns basically two types of signal plans depending on the
edge priority values at an intersection
1) streams in opposite directions at the same time, seprate phase for
exclusive left turns
2) every incoming edge gets its own phase where all turning directions get
the green light

There are a lot more valid states and signal plans so feel free to design
your own.

- You will receive a warning when loading a signal plan without yellow
phase between the green and red phase.
- When you make your yellow phases to short (relative to road speed), you
will see 'emergency braking" warnings from the simulation
- if you allow incompatible streams at the same time you may see collisions

regards,
Jakob

Re: [sumo-user] traci deceleration

[Jakob Erdmann via sumo-user]

Hello,
carFollowModels in SUMO may distinguish between a desired maximum
deceleration 'decel' and the maximum deceleration in case of emergency
'emergencyDecel'. The latter value is assumed to be at least as high as
'decel' and ultimately restricts braking capability. By default
emergencyDecel assumes the same value as decel so you may never notice the
distinction.
The fact that emergencyDecel may have a lower value than decel after
calling traci.vehicle.setDecel is a bug (
https://github.com/DLR-TS/sumo/issues/3755) now fixed.
You can either update to the latest development version or call
vehicle.setEmergencyDecel() explicitly as a workaround.

Jakob

definition to take effect like so:

Re: [sumo-user] Constrained lateral movement

[Jakob Erdmann via sumo-user]

I didn't yet find the time to test version 0.31.0 but it's working for me
in the latest development version when setting high values for maxSpeedLat
and lcAccelLat.
Therefore, it could be a bug in 0.31.0.

Jakob

Re: [sumo-user] Traci Traffic Signal Manipulation

[Jakob Erdmann via sumo-user]

Hello,
1)
- you can use the GUI to check which index corresponds to which connection
(activate 'show link tls index', see
http://sumo.dlr.de/wiki/Simulation/Traffic_Lights#Signal_state_definitions)
- you can use TraCI:
http://sumo.dlr.de/wiki/TraCI/Traffic_Lights_Value_Retrieval#Structure_of_compound_object_controlled_links
2)
This sounds like a typical OpenStreetMap Problem. See here on how to
mitigate it:

Re: [sumo-user] Cars crashing during traci calls despite tau being greater than timestep

I suspect it could be an issue with the IDM model which assumes less strict
bounds on deceleration in extreme situations. Try setting the attribute
emergencyDecel="9" for vType "rl"

Re: [sumo-user] Error message from traci

[Jakob Erdmann via sumo-user]

It means that your script (the peer) closed the connection. This causes
sumo to quit.
Try using traci.close() in your script before calling traci.start().

Re: [sumo-user] Negative Departure Time

[Jakob Erdmann via sumo-user]

Hello,
currently, the traci-api limits time-related values to a maximum of
2147483s (~24 days) and negative values may be returned after this point.
(see https://github.com/DLR-TS/sumo/issues/3439)
Since your value appears to be in the ~4day range it should not hit this
issue.
try monitoring the exact values retrieved/requested before the error.

Re: [sumo-user] The difference between Waiting time and Time loss

[Jakob Erdmann via sumo-user]

for every trip there is a hypothetical duration tMIN that could be achieved
if the vehicle was driving with its maximum allowed speed (including
speedFactor) and there were no other vehicles nor traffic rules.

timeLoss = tripDuration - tMIN
also, waiting time is always included in timeLoss, therefore
timeLoss >= waitingTime

Re: [sumo-user] tlLogic phases

[Jakob Erdmann via sumo-user]

TLC with long green duration performs better in high traffic due to the
time "wasted" at every switch.
TLC with short green duration performs better in low traffic because each
arm is served more frequently.

Re: [sumo-user] Rerouters for buses and polyconvert from shapefiles

[Jakob Erdmann via sumo-user]

Hello,
1) closingLaneReroute only causes vehicles with a rerouting device to adapt
their routes. See
http://sumo.dlr.de/wiki/Simulation/Rerouter#Closing_a_Lane
http://sumo.dlr.de/wiki/Demand/Automatic_Routing

Also, there is a known bug when using closingReroute with allow/disallow:
https://github.com/DLR-TS/sumo/issues/3633

2) Polyconvert is used to import building shapes, Points of Interest and
other map features for visualization. The default list of objects to import
from OSM is given in
https://github.com/DLR-TS/sumo/blob/master/data/typemap/osmPolyconvert.typ.xml
(highway type is not imported but can be added in a custome typemap file)

If you want to import roads from shape files you should use netconvert. See
http://sumo.dlr.de/wiki/Networks/Import/ArcView

regards,
Jakob

1) install python
2) using the command line call python xml2csv.py
yourfile.xml

   - PATH1 is the path to xml2csv.py in your sumo installation

Re: [sumo-user] Query regarding sumo behavior with lanechangemode and setspeedmode

[Jakob Erdmann via sumo-user]

Hello,
- laneChangeMode 0 also disables security checks. To disable all autonomous
changing but still handle safety checks in the simulation, use either one
of the modes *256* (collision avoidance) or *512* (collision avoidance and
safety-gap enforcement).
- By default there may only be one vehicle per lane with longitudinal
overlap. To achieve vehicles driving in parallel on the same lane without
collisions (i.e. because the lanes are wide enough to accommodate two
vehicles) requires usage of the sublane model (
http://sumo.dlr.de/wiki/Simulation/SublaneModel)
- regarding 1): This sounds strange but I would need to see your code to
determine the cause of this behavior
- regarding 2): Switching positions should not happen if the vehicles are
already driving side by side. Please send me a *minimum* scenario that
demonstrates this behavior

Jakob

Re: [sumo-user] How to get the results of the simulation

[Jakob Erdmann via sumo-user]

run your simulation with the option --duration-log.statistics and --log
logfile.txt
you will find the results in logfile.txt

Re: [sumo-user] How to generate 1500 number of vehicles in SUMO with specific routes?

[Jakob Erdmann via sumo-user]

5s yellow phase should normally be sufficient.
Please observe the vehicle that is performing emergency braking in the
simulation:
- what is the speed limit on the edge before the traffic light?
- what is the vehicle speed?
- what is the distance of the vehicle to the intersection at the time it
switches to yellow?
- what is the distance of the vehicle to the intersection and what is its
speed  at the time it starts braking?

[sumo-user] Migration to GitHub

[Jakob Erdmann via sumo-user]

Dear friends and users,
our migration to GitHub and Eclipse (
http://sumo.dlr.de/wiki/Eclipse_Migration) has a major step scheduled for
the coming weekend. Beginning on October 27th we will switch the
subversion repository
hosted on Sourceforge  and the
accompanying issue tracker  into
read-only mode.
We plan to have our new repository  ready on
GitHub on 1st November.
Please make sure to update your version control client and working copy
paths if you want to stay up to date on sumo development. The download
links for our nightly build remain the same.

best regards,
The SUMO Team

Hello,
there is no library function to accomplish your goal directly. However,
using sumolib (http://sumo.dlr.de/wiki/Tools/Sumolib) you can retrieve the
geometry of an existing network and then perform arbitrary geometrical

Re: [sumo-user] Fuel consumption in sumo

[Jakob Erdmann via sumo-user]

Hello,
fuel consumption also depends on accel/decel and for some models on slope
as well.
For further reading see http://elib.dlr.de/89398/
The source code for the models is in utils/emissions. The core component is
the compute() function of the Helpers* classes.

the default speed mode is 31. Please check whether the vehicles have

Re: [sumo-user] * is not downstream the current route. traci.vehicle.setBusStop problem

[Jakob Erdmann via sumo-user]

Then the error message is correct in stating that "the stop is not
downstream the current route". At this point you could
either use a different stop or compute a route the cycles back to the start
of the stop edge.
For the latter case it should be sufficient to call vehicle.setVia(vehID,
stopEdgeID) followed by vehicle.changeTarget(vehID, stopEdgeID)

Jakob

Re: [sumo-user] Emission Output Timer

[Jakob Erdmann via sumo-user]

Hello,
patching sumo is probably the easiest solution for your problem.
Put your check into the file microsim/output/MSEmissionExport.cpp
Alternatively, you could write the file to a socket and filter the data
with another script before writing it to disk (
http://sumo.dlr.de/wiki/Basics/Using_the_Command_Line_Applications#Writing_files

Re: [sumo-user] Adding penalties to current travel times.

[Jakob Erdmann via sumo-user]

The travel_time * penalty approach you describe is the most flexible and
general approach.
You could achieve a similar effect (automatically updated travel times,
some customization via TraCI) with device.rerouting.

[sumo-user] 0.31.0 Bug notification

[Jakob Erdmann via sumo-user]

Dear users,
Please note that a bug was introduced in Netedit version 0.31.0  that
appears when saving networks which contain pedestrian crossings controlled
by a traffic light (http://sumo.dlr.de/trac.wsgi/ticket/3472).
It causes crossing to be uncontrolled. If you use Netedit to create
pedestrian scenarios, it is recommended that you upgrade to the development
version. Affected networks can be fixed by loading and saving them with
netconvert 0.31.0 or a later version.
  netconvert -s bugged.net.xml -o fixed .net.xml

Jakob

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

[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.

Jakob

Re: [sumo-user] Needing more information for platooning model

[Jakob Erdmann via sumo-user]

Hello,
are you trying to implement a new model within sumo (C++) or are you trying
to control the simulation via TraCI?
In either case, the acceleration is implied in the change of speed from one
step to the next.
Within sumo you can call MSVehicle::getAcceleration() and from TraCI you
need to record the speed from the previous step for each vehicle in order
to compute acceleration.
To get the leader of a platoon you can call getLeader repeatedly (on the
previous leader) until the distance to the next leader crosses some
threshold you find suitable.

Jakob

Re: [sumo-user] Vehicle gets routed through off-line station!?

[Jakob Erdmann via sumo-user]

Hello,
edge priority is not taken into account for routing purposes. Neither is
the number of junctions (or rather not in the correct way).
The speed should take effect but you may be suffering from a known issues
of junction distances being ignored and thus getting wrong distance
estimates: http://sumo.dlr.de/trac.wsgi/ticket/752
As a workaround, try redrawing the junctions to make them smaller and
decrease the speed in the offline station somewhat.

Re: [sumo-user] Simulated detector problems

[Jakob Erdmann via sumo-user]

Hello

 1) maybe Andres can extend the code in traci4matlab/examples
 2) you may not use xml comments within an xml element as done for detector
4 (the <-- part)

Re: [sumo-user] How do I get the time duration of green traffic light on a particular edge via traci4matlab?

[Jakob Erdmann via sumo-user]

First you need to determine the traffic-light index which corresponds to
that edge (or rather to the lane-to-lane connections from that edge because
each connection has it's own index).
This is done by calling the function trafficlights.getControlledLinks.

Then you can retrieve the state with getgetRedYellowGreenState and
interpret it using the respective index)
By calling getDuration getNextSwitch you can figure out all there is to
know about spend and remaining duration (see the explanation at
getPhaseDuration)

Jakob

Re: [sumo-user] How are position and velocity computed when turning left/right at intersections?

[Jakob Erdmann via sumo-user]

Hello,
by default, vehicles drive on so-called "internal edges" while passing an
intersection. They follow the car follow model just as on normal
edges/lanes. You can see these edges when you disable the option "draw
junction shape" in the gui visualisation settings. Only if you have built
your network with the option --no-internal-links will vehicles "jump" over
intersections.

Jakob

Re: [sumo-user] How to convert junction to edge?

[Jakob Erdmann via sumo-user]

Hello,
the small dark red dots are geometry points within an edge. They can be
used to model curves without changing the edge id. Whenever the number of
lanes changes or there is an intersection of 3 or more roads, all edges
must have a unique id. In the norther intersection of your screen shot,
(with the 5 red junctions in close proximity) only the central junction is
needed. The others can be converted into geometry points (right-click and
select 'replace by geometry node'). You can right click all junctions and
you will see whether they can be converted. In version 0.31.0 you will also
see a reason if conversion is not possible.

Jakob
