Dear SUMO community. We were testing the KraussPS model in cities with high road slope such as Medellin and San Francisco. We imported the height data using GeoTiff, as explained in http://www.sumo.dlr.de/2014/Presentation_Keynote_Open%20data%202014_MarioKrumnow.pdf and found that, using this model, vehicles get stuck in the simulation if the road slope is > 15.2789°, having into account a default max accel of 2.6 m/s2, as found in the maxNextSpeed method of the model:
const SUMOReal gravity = 9.80665; const SUMOReal aMax = MAX2(0., getMaxAccel() - gravity * sin(DEG2RAD(veh->getSlope()))); // assuming drag force is proportional to the square of speed const SUMOReal vMax = sqrt(aMax / getMaxAccel()) * myType->getMaxSpeed(); return MIN2(speed + (SUMOReal) ACCEL2SPEED(aMax), vMax); How can we fix this? -- Andres Felipe Acosta Gil, MSc student - Software developer Universidad Nacional de Colombia - Medellín Facultad de Minas Tel: +57 (4) 4255295 Institutional e-mail: [email protected] ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ sumo-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sumo-user
