Until the point I run my simulation I have 319 arrived vehicles. As far as I can understand those vehicles should not be stored in the state file (they also don't have a trip info device). Moreover there are exactly 319 "broken" routeDistribution tags (the ones that correspond to the arrived vehicles). Because I used SUE (max alternatives = 5) in one distribution I may have 1 or more (until 5) possible routes. I give an example of a broken routeDistribution: The vehicle with id "7107" is an already arrived vehicle. The vehicle in the route file is depicted as follows: >>> fromTaz="in_18" id="7107" toTaz="left8" type="warm_up_car"> >>> probability="1.33352733"/>(!7107#0) >>> probability="1.32770984"/>(!7107#1) >>> probability="1.33876284"/> (!7107#2) The vehicle during the simulation used the route edges="D6D7 D7C7 C7B7 B7A7 A7A8 A8left8" which corresponds to !7107#2 which is the missing route id from the state xml file.

Re: [sumo-user] Mismatch in Traffic Density in SUMO:
I'm afraid I don't even understand your requirement. The statement "so that it won't affect ... density" is a contradiction to your earlier problem of "traffic density does not match" Also, "density" is intrinsically linked to the number of vehicles in the scenario. Doing any change to vehicle insertion (the way a scenario is "populated") will affect density. Thus there is no feasible advice to give on insertion that won't affect density. Am So., 18.

Re: [sumo-user] help understanding how to repeat car insertion on a route
the 'repeat' value of a route is for circular routes (the edges repeat). For repated vehicles, you need to define a flow (in vehicle mode). You can read about the concept here: https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#repeated_vehicles_flows There are also tutorials/videos on flows: https://sumo.dlr.de/docs/Tutorials/index.html#sumo_user_conference_tutorials Am Mo., 19.

[sumo-user] help understanding how to repeat car insertion on a route
Hello, I simply want multiple cars to enter the simulation one after the other at some interval. In the route dialog, in inpsector mode, If I try to set the value of repeat to a positive integer, and use a cycle of say a few seconds, I get this error: Error: Disconnected route 'r_0' when repeating. What am I misunderstanding here? Thanks in advance for any help or suggestions.

Re: [sumo-user] Mismatch in Traffic Density in SUMO:
Respected Sir, In my simulation scenario, there is no presence of leading vehicles and due to that speed remains high throughout the simulation, which is also visible in attached results. Therefore, kindly suggest me that how can I populate the traffic in real scenario, so that it won't affect my traffic parameters like speed and density while doing the simulation.
