Re: [sumo-user] Question about reproducing the phenomenon "capacity drop"

Yes. Using by using departPos="random_free", vehicles are inserted with lower speeds and slightly higher densities which makes the drop already appear without even setting lcCooperative. By setting lcCooperative you reduce the merging efficiency and thus increase the capacity drop. regards, Jakob

Re: [sumo-user] Adding a stopped vehicle outside the network and setting a route

Jakob, Sorry for the late reply. Thanks again! After testing with latest version from github I can confirm that the issue is resolved. While testing I did encounter another issue. Looks like if I call moveToXY after adding the vehicle with a position that is on an internal edge (e.g. junction), Su

Re: [sumo-user] Low flow in lane with flowrouter

I'm afraid the lane-based option has been neglected during development. Until today there wasn't even a test for this and I've never used it productively. Since the algorithm doesn't consider lane-changing when using option --lane-based it fails to find routes in many typical network layouts (http

Re: [sumo-user] Question about reproducing the phenomenon "capacity drop"

Hello Jakob, Thanks very much for your reply. You are absolutely right. Now I have set the merging area with four lanes but the downstream mainline with three lanes. Also, I have increased the input volume with the attributes departPos="random_free" and departSpeed="max". I didn't changed th

Re: [sumo-user] Low flow in lane with flowrouter

Hi Jakob, Those are some great suggestions, thanks. I see now looking through the sourcecode that there is an option --lane-based, does this mean that I could get the output per lane instead then? In regards to changing the aggregation time, will I get vehicles all coming in chucks every 5 min

Re: [sumo-user] emission-output

Unfortunately, emission-oputput does not allow filtering at the moment. If the sum of emissions for each vehicle are sufficient you can use tripinfo-output and equip selected vehicle types with an emission device. The emissions will then be included in the tripinfo-output results. regards, Jakob

Re: [sumo-user] Question about reproducing the phenomenon "capacity drop"

Hello, the answer to this is a bit complex, sorry. - capacity drop is negatively correlated with lane count in reality. With default settings you should be able to see it if the main line has only 1 lane (2 lanes in the merging section) - capacity drop can only be observed if the entering flow of

Re: [sumo-user] Low flow in lane with flowrouter

Flowrouter only sums up the lanes and doesn't concern itseelf with flow per lane So there are two seeprate issues to this: 1) total flow: Looking at time 90, the simulation has a deficit of ~1300 vehs/hour. This could be due to the low aggregegation interval of 1 minute because flowrouter does not

[sumo-user] Question about reproducing the phenomenon "capacity drop"

Hello, I am simulating the traffic in the merging area where vehicles come from the one-lane on-ramp and the three-lane mainline. I hope to reproduce the phenomenon "capacity drop" that means the discharge rate is less than the capacity in the downstream mainline. I have tuned some parameters b
