Hello, a problem was discovered in moveToXY and fixed yesterday (revision [22217]). Please try out the latest development version: http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version best regards, Jakob

The problem is that sometimes the vehicle is moved to the > wrong lane (or even road) when the arguments (xyposition, angle) should > result in a different situation. To illustrate this, I attach an > explanatory figure, and describe the situation here: > > - I use the traci command *traci.vehicle.moveToXY(hostID, > EdgeIDPosition[0], 0, Positionxy[0], Positionxy[1], curAngle, > keepRoute=0)*, > where: > - *hostID* is the ID of the desired vehicle. > - *EdgeIDPosition[0]* is the ID of the identified edge using the > class traci.simulation.convertRoad and lat/lon coordinates. > - *Positionxy* is a 2D vector with the calculated XY position from > the lat/lot coordinates. > - *curAngle* is the desired vehicle's angle. > - I then compare the angle of section of the edge in which the vehicle > has been moved at with the vehicle's angle, and if they are similar in a > range of +/- 45 degrees I consider a fair map-matching and change the > vehicle's colour to green; otherwise I change the colour to red. > > Thus, as you can see from the attached figure, sometimes (I'd say, many > times) the map-matching just does not work, and the vehicle is moved to the > wrong lane. One easy way to check the faulty map-matching is by looking at > the provided GPS position (marked with a POI) and the vehicle's orientation > (given by the desired vehicle's angle I provide), this latter opposed to > the direction of the lane at which the vehicle is wrongly map-matched. > > So, I hope you can help me out in solving this problem (in case I am doing > something wrong, which I really doubt), or in fixing this bug in the next > SUMO version. > > Many thanks for your valuable help. > > Best regards, Rodrigo. > > -- > Rodrigo Hernán Ordóñez-Hurtado, PhD > Research Fellow > University College Dublin > > ------------------------------------------------------------ > ------------------ > > _______________________________________________ > sumo-devel mailing list > sumo-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/sumo-devel > > ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
