Thank you for your reply. I changed the VType and was able to reduce the difference in arrival time a bit. However, there is still a big difference. After observing the simulation, there is still a deceleration of 1 to 2 m/s at the junction and I think this is one of the reasons. For reference, I changed the limitTurnSpeed in net.xml from 5.5 to 13.88, but the speed through the junction is still 6~7m/s. Looking at the following page, is it not possible to change the speed for the safety of the car? https://sumo.dlr.de/docs/Simulation/Safety.html
Other than changing limitTurnSpeed, is there any other way to change the speed through the junction? regard, Nishikawa ----- Original Message ----- From: Jakob Erdmann <[email protected]> To: Sumo project User discussions <[email protected]> Date: 2021-05-18 16:02:21 Subject: Re: [sumo-user] Obtaining the estimated time of arrival of the vehicle In the simulation, there are some random factors that affect vehicle speed. See https://sumo.dlr.de/docs/Simulation/Randomness.html You can eliminate them by re-configuring the vType with sigma="0" speedDev="0". Note, that there can still be interaction at junctions which are not predicted by duarouter. Am Di., 18. Mai 2021 um 07:57 Uhr schrieb g2121044 <[email protected]>: Hello. I have a question about this email. https://www.eclipse.org/lists/sumo-user/msg09369.html I forgot to include the net.xml information in this email. The conditions I used in my simulation are ・No traffic lights ・No randomly generated general vehicles (only demand cabs) ・Equal speed limit on the map The conditions are as follows Even though I eliminated all factors that affect the arrival time of the vehicles, there was a difference between the exitTime and the simulation time. The difference is created even when the vehicle is running in a straight line. This difference seems to grow in proportion to the distance traveled. For example, if I want to know the estimated time of arrival of a demand cab, is there any way to know it other than using duarouter(--exit-time)? I'm sorry for repeating myself. regard, Nishikawa _______________________________________________ sumo-user mailing list [email protected] To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user
