Hello Mr. Jakob, I am very sorry once again, but it still does not work.

When I use this:


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

I get these outputs to use in moveToXY:

x2=4.956658 y2=22.982225
x2=5.009388 y2=34.633814
x2=5.097475 y2=45.349363
x2=4.368089 y2=57.215837
x2=4.624426 y2=69.318226
x2=5.126126 y2=81.546192
x2=4.925263 y2=95.019266
x2=4.932274 y2=108.620357

and the vehicle drives on the left side of the road.

If I use what you said :

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

I get this kind of output:

x2=-561578.553342 y2=-4188031.457775
x2=-561578.500612 y2=-4188019.806186
x2=-561578.412525 y2=-4188009.090637
x2=-561579.141911 y2=-4187997.224163
x2=-561578.885574 y2=-4187985.121774
x2=-561578.383874 y2=-4187972.893808
x2=-561578.584737 y2=-4187959.420734
x2=-561578.577726 y2=-4187945.819643
x2=-561578.277498 y2=-4187931.796405
x2=-561577.983976 y2=-4187918.083758

and the vehicle is nowhere to be seen.

Is there anything I can do to fix this issue?

Thak you very much for your help.

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)

Hello Mr Jakob,


I am sorry to bother again, but I replaced the line of code I had with the one 
you provided, and the simulation looks just the same. The vehicle drives by the 
side of the road the whole time, and it also seems not to have the right angle. 
This is how my code looks like now:


x,y = df_dropped_1st_veh_instance['Local_X'].iloc[k], 
df_dropped_1st_veh_instance['Local_Y'].iloc[k]
lon, lat = net.convertXY2LonLat(x * 0.3048, y * 0.3048, True)
x2, y2 = net.convertLonLat2XY(lon, lat, rawUTM=True)

traci.vehicle.moveToXY(traci_veh, '', 0, x2, y2, angle, 2)

for the angle I used INVALID_DOUBLE_VALUE and transformed it to radians.

Here is a sample of the data I have:

       Local_X   Local_Y     Global_X     Global_Y
0       16.467    35.381  6451137.641  1873344.962
1       16.447    39.381  6451140.329  1873342.000
2       16.426    43.381  6451143.018  1873339.038
3       16.405    47.380  6451145.706  1873336.077
4       16.385    51.381  6451148.395  1873333.115
5       16.364    55.381  6451151.084  1873330.153
6       16.344    59.381  6451153.772  1873327.192
7       16.323    63.379  6451156.461  1873324.230

Thank you in advance,

Thais Gama

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

Hello Mr. Behrisch<https://sourceforge.net/u/behrisch/> / 
Erdmann<https://sourceforge.net/u/namdre/>,


I would like to know if there is a way in SUMO that I can directly use CA State 
Plane NAD83 coordinate in feet to move vehicles in a network with the moveToXY 
command, or do I need to do any transformations before hand?


When I use this piece of code (I got from 
http://sumo.dlr.de/wiki/Tools/Sumolib#coordinate_transformations) I seem to get 
reasonable results for latitude and longitude, but the x and y resulting from 
conversion are not matching the network. When I run this code:


x,y = df_dropped_1st_veh_instance['Local_X'].iloc[k], 
df_dropped_1st_veh_instance['Local_Y'].iloc[k]
#x, y = traci.vehicle.getPosition(traci_veh)
lon, lat = traci.simulation.convertGeo(x, y)
x2, y2 = traci.simulation.convertGeo(lon, lat, fromGeo=True)
#x, y = net.convertLonLatXY(lon, lat)
print 'x=%4.6f y=%4.6f' % (x2, y2)

the vehicle drives off the road network the whole time. In this case I am using 
the local coordinates (Local_X and Local_Y) which are described as: "Lateral 
(X) coordinate of the front center of the vehicle with respect to the left-most 
edge of the section in the direction of travel". When I use the Global 
coordinates (Global_X and Global_Y) my vehicle will just stand outside the 
network for the whole time, and those are the actual geo coordinates, described 
as such: "CA State Plane NAD83 coordinate".

i know my network is in datum=WGS84, by the information given in the network 
xml file, and that it is shifted by the netOffset parameter.

I wonder if that might be the problem?

<location netOffset="-561583.51,-4188054.44" 
convBoundary="205.71,83.75,327.03,729.01" 
origBoundary="-122.300034,37.837827,-122.295689,37.846489" 
projParameter="+proj=utm +zone=10 +ellps=WGS84 +datum=WGS84 +units=m +no_defs"/>


PS.: i need high accuracy and precision, the vehicles should move exactly 
according to my coordinates, provided in the data I have. The data is very big 
(more than 1Gb), so I am sending only a subset of it, which refers to one car 
only. And also my code and files to run the simulation, in case those are 
needed.


Thank you in advance for your help,


Thais
