Hello, you have several options: 1) generate individual attributes accel, decel, speedFactor for each vehicle 2) generate a parameter distribution fora accel, decel and speedFactor from the data (http://sumo.dlr.de/wiki/Tools/Misc#createVehTypeDistributions.py)
3) pick one representative value for accel and decel and (mean) speedFactor and only use speedDev to model the speedFactor distribution. For this case I would recommend (note, that speedFactor is defined with reference to the speed limit): accel = max acceleration (use the 90th percentile to make this robust) decel = max deceleration (use the 90th percentile to make this robust) speedFactor = mean of (maximumSpeed/speedLimit for each vehicle) speedDev = deviation of (maximumSpeed/speedLimit - speedFactor) regards, Jakob 2017-08-31 10:33 GMT+02:00 Alessandro Virgilio via sumo-user < [email protected]>: > Hi all, I have a problem about defining vehicles in my simulation. > I have data about real vehicles such as instant speed and acceleration. > Then I calculated mean, deviation, maximum and minimum (for the speed) and > max and minimum acceleration for each vehicle. > Is there any way to simulate a vehicle having the same characteristics? > > My only idea is to define a vehicle type with these atttributes: > accel = max acceleration > decel = min deceleration > speed factor = speed mean > speed dev = speed deviation > > I know that the actual beaviour of a vehicle depends on other factors, such > as lane speed limit, traffic etc. But I would simulate into an ideal case > in which the data obtained with the simulation is similar to the real one > (in the same conditions). > > Thank you all. > > Regards, > Alessandro Virgilio > ------------------------------------------------------------ > ------------------ > 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 > _______________________________________________ > sumo-user mailing list > [email protected] > To change your delivery options, retrieve your password, or unsubscribe > from this list, visit > https://dev.eclipse.org/mailman/listinfo/sumo-user > ------------------------------------------------------------------------------ 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
