 Hi Jakob,
 I have add the option numTries=100 to traci.start(),but the error is

Onderwerp: Re: [sumo-user] dealing with bicycles in routes

There are two possible candiate reasons for the described symptoms:
1) the bicycles given to duarouter are not configured as bicycle but rather as 
passenger cars (vClass="bicycle" is required to allow driving on bicycle lanes).
2) the bicyle routes require intermediate usage of passenger-car-only lanes. 
You can use SUMO-GUI to highlight all edges for a specific vClass by selecting 
'Edit->Selectlanes which allow->...' from the main menu.

Dear SUMO-users,

I have another issue.

As many will probably know we have a lot of cycle paths in Holland, also around 
traffic controlled intersections. I made special edges fort he cyclists which 
allow only bicycles. This results in het net-file in red bicycle paths around 
the intersection, which is perfect.

I then made flows in the route-file with bicycle flows of every quarter within 
a day, just like I did with motorized vehicle. But the I get errors running 
duarouter with the message the connection can’t be found.

I found the solution for this. When I allow not only bicycles but also 
passenger (cars), it works. This is workable, but not completely right in my 
opinion. The main thing now is the bicycle paths aren’t colored red anymore. 
Also when I change the net-file afterwards, I get error messages from the 
route-file. So it isn’t possible to make route-trips when the edge doesn’t 
allow passengers? Is there another solution to color edges?

Re: [sumo-user] Fully Controlled Vehicle

[Jakob Erdmann]

SUMO assumes control of vehicles as soon as they are no longer controlled
remotely. This also resets their angle to the road angle. If you call
simulationStep with a 1000ms increment but the simulation runs at 10ms then
the angle will definitely be reset because the vehicle is under SUMO
control for 99 steps out of 100.

 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.

 Jakob

[sumo-user] Questions regarding pedestrians/passengers

[Brandon Penaranda]

Greetings!

I am currently using SUMO's source code and was wondering if it is possible
to make pedestrians into something similar to mobile bus stop to simulate a
pedestrian boarding and departing a bus wherever they please as long if the
vehicle is closest to the pedestrian's edge . If it is possible, may I know
what are the classes and methods needed to be changed?

Sincerely,
Brandon.

[sumo-user] Fwd: Fully Controlled Vehicle

[Timothée Corsini via sumo-user]

Hi,

Thanks for the quick answer. I've made a mistake in my previous message, I
meant that even if I chose an angle (for exemple 40°), Sumo will adapt the
orientation of the car according to the edge, I would like Sumo to not do
that, here is how I create a car :

mSumoClient.vehicle.add(vID, string("route0"), vType);
mSumoClient.vehicle.moveToXY(vID, string(""), 0, pos.x, pos.y, 135.0, 2);
mSumoClient.mySetLaneChangeMode(vID, 0);
mSumoClient.mySetSpeedMode(vID, 0);
mSumoClient.vehicle.setSpeed(vID, 0);

(vID, vType are strings and pos is a Position type, mSumoClient comes from
the TraCIAPI class, as for the functions mySet... they weren't implemented
in the C++ version so I wrote them by referring to the Python
implementation of TraCIAPI)
The map used is two roads of 1 km (one is horizontal, the other vertical)
crossing themselves at the center of the map but not recognizing themselves
(There is no node representing the intersection). When I create a car, if
it's outside the road network, the car has the orientation expected (135°)
but if it's in an edge, it will be orientated according to the lane
direction (so for the vertical edge : 0° or 180°). I would like to prevent
this.

regards,
Timothee Corsini

Re: [sumo-user] Disconnect with Traci

[Jakob Erdmann]

Possibly. Unless the error is caused by SUMO closing with an error before
opening the socket.
You can run multiple simulations on the same connection by using the
function traci.load
See http://sumo.dlr.de/daily/pydoc/traci.html#-load

 If you create a log file for every sumo run you can look for the
 problem in the latest logfile:

 for i in range(2):
traci.start([sumoBinary, "--start","-c", "data/cross.sumocfg",
   "--tripinfo-output", "tripinfo.xml", "log",

 - Possibly the simulation cannot start in time because the computer
 is still busy from closing the previous simulations. You could add the
 option numTries=100 to traci.start() to diagnose this
 - Possibly, the simulation cannot start successfully because your
 computer is out of memory (which might indicate a memory leak in sumo).

Hi Jakob.
If I have the error"Could not connect to TraCI server at ..",will this be
solved by repeating the simulation in the same traci connection?If  yes
,how?

 Hi Jakob，
 Thank you,it works.But the problem is also exist,it retries for 101

 also occurred the error that "connection closed by SUMO",If you want more

 Hi,
 My SUMO version is 0.32.0,and I write a loop to simulate for many
 times, I start SUMO like this:
 for i in range(2):
 traci.start([sumoBinary, "--start","-c", "data/cross.sumocfg",
   "--tripinfo-output", "tripinfo.xml"])
 ...
 ...
 traci.close()
 At the beginning,it works well,but it may disconnect with traci and
 the time points is different.I don't know what's wrong.

Re: [sumo-user] dealing with bicycles in routes

[Jakob Erdmann]

There are two possible candiate reasons for the described symptoms:
1) the bicycles given to duarouter are not configured as bicycle but rather
as passenger cars (vClass="bicycle" is required to allow driving on bicycle
lanes).
2) the bicyle routes require intermediate usage of passenger-car-only
lanes. You can use SUMO-GUI to highlight all edges for a specific vClass by
selecting 'Edit->Selectlanes which allow->...' from the main menu.

Jakob

Re: [sumo-user] Issue during route creation

[Jakob Erdmann]

Hello,
1) see
http://sumo.dlr.de/wiki/FAQ#What.27s_the_deal_with_schema_resolution_warnings_.2F_xsd_errors.3F
2) we do not have an interface for unreal/unity. SUMO can be built with
OpenSceneGraph support for 3D-Visualisation but this is rather experimental.

[sumo-user] Issue during route creation

[yuvika.dev--- via sumo-user]

Hi,


I am learning SUMO simulator for our project work .


1.As part of learning when I am trying to run the examples given under  
/tests/complex/tutorial/traci_pedestrian_crossing/



Warning: Cannot find local schema 
'/usr/lib/sumo/data/xsd/connections_file.xsd', will try website lookup.



Error: unable to resolve host/address 'sumo.dlr.de'

 At line/column 1/0.

Error: No nodes loaded.
Quitting (on error).
Network file 'pedcrossing.net.xml' not found

Even If I tried creating my own network file and then try using randomTrip to 
generate route file , same problem

python /home/adas/Documents/Wipod/Simulator\ -\ SDV\ in\ a\ 
Box/SUMO/sumo/tools/randomTrips.py --net-file=hello.net.xml -r hello.rou.xml -e 
50 -l

Re: [sumo-user] Questions about lane change mode (0xb6) and speed mode (0xb3)

[Jakob Erdmann]

Hello,
1) the safety gap is computed as if the vehicles were in a car-following
relationship on the target lane. This means it is subject to car-follow
model parameters. In the latest development version, all lane change models
support the parameter lcAssertive which allows modifying the computed
safetey distance by a custom factor.

2) it means that the ego vehicle and other vehicles will adapt their speed
so that lane change becomes possible (if it isn't possible at the moment).
If the speed is overwrittten by setSpeed than this coordination may not
work.

3) If all checks are on, the highest priority is given to maximum
deceleration (attribute emergencyDecel), then safe speed then acceleration

Jakob

Re: [sumo-user] Fully Controlled Vehicle

[Jakob Erdmann]

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.

Jakob

[sumo-user] Questions about lane change mode (0xb6) and speed mode (0xb3)

[Tong, Kailin]

Dear SUMO users,

In 
http://sumo.dlr.de/wiki/TraCI/Change_Vehicle_State#lane_change_mode_.280xb6.29

It says:
To disable all autonomous changing but still handle safety checks in the 
simulation, either one of the modes 256 (collision avoidance) or 512 (collision 
avoidance and safety-gap enforcement) may be used.


  *   When the mode is 512, how is the safety-gap of others calculated?

bit9, bit8:
* 00 = do not respect other drivers when following TraCI requests, 
adapt speed to fulfill request
* 01 = avoid immediate collisions when following a TraCI request, adapt 
speed to fulfill request


  *   What is adapt speed to fulfill request means here? What will happen if 
the speed is overwritten by traci.vehicle.setSpeed ?


In http://sumo.dlr.de/wiki/TraCI/Change_Vehicle_State#speed_mode_.280xb3.29


  *   If all checks of speed mode on, traci.vehicle.setSpeed sets a speed over 
the safe speed / maximum acceleration / maximum deceleration, which one has a 
higher priority?


Thank you in advance!

Best regards,
Kailin

[sumo-user] Fully Controlled Vehicle

[Timothée Corsini via sumo-user]

Hi !

I am currently using SUMO with another software by using the TraCIAPI in
C++. I managed to represent SUMO vehicles in the other software but now I
would like to represent the vehicles from the software in SUMO.

However, I do not want these vehicles to move or change their orientation
unless I ask them to. So I changed their speed, their speedMode and
laneChangeMode to 0, and I am moving them by using the moveToXY function.
Still, SUMO does not change their angle in order to adpat them to the
edges, I would like to avoid that, is it possible ?

In fact I would like to control some vehicles without SUMO trying to
teleport/move/remove them. (but still being recognized as obstacles by the
others vehicles) Is that possible ?

Else, can I simply put obstacles of the shape I want on the road (for
exemple representing a car accident) or do I have to close the lanes
manually in order to stop the traffic ?

Sorry for the butchered langage.

Regards,
Timothee Corsini

Re: [sumo-user] Disconnect with Traci

[Jakob Erdmann]

If you have the error "connection closed by SUMO" this would not be solved
by repeating the simulation in the same traci connection. Diagnose it using
logfiles as explained in my last email.

 Hi Zhiqiang,

 it could be helpful if you provide some more details:
 Under what circumstances does the connection fail? Do the
 circumstances
 during failure differ from before? Does it disconnect while it is
 connected, or not connect at all? Etc.
 Also, how are you starting SUMO, manually, programmatically? Etc.

 Hi,
 Could you please tell me how add the option numTries=100 to
 traci.start()?

 Best regards,
 Zhiqiang

Re: [sumo-user] TraCI, getLoadedIDList and missing vehicles.

[Jakob Erdmann]

That should not happen. Every vehicle that is ever built should be part of
that list.
Please provide input files for reproducing this situation.

Jakob
