Hello, the two outpufiles generated by flowrouter.py (routes and flows) must be used together. This can either be done by adding the routes with option --additional or by using duarouter in a preprocessing step (load routes, flows and network to create a combined file with lots of vehicles).
The whole idea of combining flowrouter (or any other tool that creates routes from counting data) with duaIterate to ease congestion is questionable though, because the new routes may ignore the original edge count values that were used with flowrouter. Flowrouter is known to generated "implausible routes" which are more likely to cause congestion in some networks. There are two approaches to deal with this problem - identify and blacklist "implausible" routes to guide the flowrouter process - use another tool See https://sumo.dlr.de/docs/Demand/Routes_from_Observation_Points.html#chosing_the_right_tool regards, Jakob Am Sa., 13.
