Re: [sumo-user] DFROUTER Detector type is discarded for most of detectors

Hi Jakob, Thanks for your answers and your presentation at the user conference on youtube. I still have a question about the flow data units to be used in flow files for DFROUTER and flowrouter.py. The documentation in two different pages seems inconsistent, which inturns create confusion about

Re: [sumo-user] Gap acceptance in lane changing

1) Yes 2) you can set minGap=0 to lower the size of accepted gaps. At high speeds you will not see adverse effects but gaps will probably appear too small at lower speeds. Some car-following models such as IDM require minGap as an additional buffer for collision-free driving. Am Fr., 19. Juni

Yes. This should work. It is working for a 4-arm intersection in our own C++ client test. I'm assuming that you are using the C++ client and linking against src/utils/traci/TraCIAPI.h How did you check the TraCI version? Am Mo., 15. Juni 2020 um 10:28 Uhr schrieb zipfl : > Hello, > > I'm

Re: [sumo-user] Routing based on traffic density

Yes. routeSampler should work for this. Edge-data files can be created manually with netedit and also from text-based formats of detector data. However, if your density data comes from a database or some other kind of format the easiest solution is to write a small data-transformation script. You

Re: [sumo-user] Connecting multiple routes

For each physical vehicle you can define a and then concatenate all stops that the vehicle is supposed to service over the day. The simulation will automatically compute the route to connect all those stops. Am Di., 16. Juni 2020 um 23:31 Uhr schrieb Maximilian Socher <

[sumo-user] Routing based on traffic density

Hello, I have a question regarding edge based routing. I have access to traffic density data on edge granularity in hourly steps and would like to know if there is an implementation in SUMO, which generates routes from this kind of data or upscales a subset of routes (I can get around 5% of the

Re: [sumo-user] Gap acceptance in lane changing

1.So, the requireGap, depends on the followSpeed. And followSpeed should be also influenced by “tau”. Then the requireGap is always a function of tau. Is this right? Can I say, if I have a distribution for tau, I will have a variation for gap acceptance (requireGap)? 2.And

Re: [sumo-user] Gap acceptance in lane changing

1) yes 2) these are computed by the car-follow model functions. They generally are consistent with the followSpeed function so that neither the ego vehicle nor its follower on the target lane have to perform any extra braking after the lane change is completed. 3) if a jam develops immediately

[sumo-user] Gap acceptance in lane changing

Hi there, I am trying to investigate the impact of gap acceptance in lane changing around on-ramps on the capacity of a freeway. I want to use a distribution for the gaps accepted while lane changing. I realized that the parameter which controls the gap acceptance is "lcAssertive" (But if I

Yes. tripId is currently not interacting with repeated laps or flow vehicles. It was implemented for the use case of importing a complete schedule in "uncompressed form" from an external data source (gtfs etc) In this use case no flows or route-repeat definitions are used. Instead each vehicle is
