Re: [sumo-user] rerouting algorithm

Hi, no, there are different algorithms used for rerouting. The standard one is Dijkstra, see here: https://sumo.dlr.de/docs/Simulation/Routing.html#routing_algorithms and the links there. Best regards, Michael Am 13.10.20 um 19:08 schrieb Jane Cheung: > Dear all  > One question about the reroutin

Re: [sumo-user] Clarification

Hi, https://sumo.dlr.de/docs/Simulation/Output/SSM_Device.html#output states that the conflict point is the entry point into the conflict area, so the first point where a critical value has been reached. It may be interpolated between vehicle positions while ego and foe position are always position

Hi Xun, I do not fully understand wha you are trying to achieve. The sources and destinations are given and you want to assign them randomly to each other? Or do you want random volumes between fixed pairs? The routes should be shortest paths or the vehicles should turn randomly (according to given

Hi Jan, the behavior you see is an artifact of conservative estimates in the sumo code, see the comments here: https://github.com/eclipse/sumo/blob/master/src/microsim/cfmodels/MSCFModel.cpp#L855 On the other hand there is https://github.com/eclipse/sumo/issues/4134 which seems to point in the oppo

Re: [sumo-user] Different vehicle's distance results for different step-lenght

Hi, unfortunately your assumptions on the calculations are wrong. Unless you activate --step-method.ballistic sumo will first calculate the new speed v = v0 + a*dt and then assume this speed for the whole step s = s0 + v*dt. Best regards, Michael Am 25.09.20 um 20:12 schrieb nohtyp: Hi, How

Re: [sumo-user] SUMO dataset availability of long duration

Hi, if you really need different mobility patterns (more shopping and leisure activities on weekends and more commutes on weekdays) you are probably out of luck. What we usually do is simple scaling by a constant factor for weekends and keeping weekdays identically. Best regards, Michael Am

Hi Jane, there is no way to do this with sumo alone. Depending on the operating system you use you could write the data to a socket or a named pipe and read and filter it from there without an intermediate file. The xml2csv.py might be an option as well. Best regards, Michael Am 20.08.20 um 14:52
