Hello, the simulation uses the lane lengths from the net.xml. Possible sources of discrepancy: - forgetting to count the lengths of internal lanes (lanes within intersections) - distance traveled in the last stop before leaving the network (i.e. the vehicle travles 20m/s in the last step but only drives 10m in the network and then the route ends) - integration method to compute distance from speed: By default sumo uses Euler integration. This means the speed in each step is converted directly into distance. You may activate ballistic integration using the option --step-method.ballistic which computes distances from the average of the speed before and after the step.
If none of the above serve as an explanation I do need a (preferably short) error example with input files. regards, Jakob 2017-03-27 14:00 GMT+02:00 Matěj Kubička < [email protected]>: > Hello, > > Is it possible that lane lengths (extracted from the .net.xml file) are > not the ones that SUMO uses in simulation?
