| Re: [sumo-user] Running duaIterate.py with flowrouter.py routes |
Hello again Jakob, sorry to bother you again.I'm still trying to launch the tool implausibleRoutes.py but it still raises the same error. I thought the problem could be in my network large extent (I need to simulate a middle-sized european city) so I clipped it to a lower extent, but the problem persists.After running flowrouter.py, I launch implausibleRoutes.py and this is what I get:Loading net ... done.
Error: No route input specified or all routes were invalid.
Quitting (on error).

FileNotFoundError: [Errno 2] No such file or directory: 'routes.xml.rerouted.rou.alt.xml'It seems that implausibleRoutes.py cannot read the routes from routes.xml, but not sure why. The routes.xml contains routes of this form:<route id="678695567_678859243.qPKW.1380" edges="678695567 80784908 136656809 92741288#1 124019581#0 124019581#2 678859243"/>Kind regards,AlejandroEl mar, 16 nov 2021 a las 10:36, Jakob Erdmann (<namdre.sumo@xxxxxxxxx>) escribió:Hello,the tool implausibleRoutes.py calls 'duarouter' in the background to find shortest paths (and thereby detect implausible detours).This call to duarouter is supposed to generate the file 'routes.xml.rerouted.rou.alt.xml'.Try running the tool with option -v to better understand what's happening.It should print the 'duarouter' command on the console and you can also try to execute this command yourself to check for errors.regards,Jakob._______________________________________________Am Mo., 15.

Regarding the "implausible routes", I'm experiencing some difficulties with the "implausibleroutes.py" script since a while, that is why I started to look for alternatives.When using python implausibleroutes.py network.net.xml routes.xml, I have the following error:FileNotFoundError: [Errno 2] No such file or directory: 'routes.xml.rerouted.rou.alt.xml'Which makes sense because my routes file hasn't that name. Searching in the code, it seems to me that the error may come from the "duarouterAltOutput" definition shown below that. But I don't really know what to do to get rid of this error. It doesn't not work with absolute paths neither.prefix = os.path.commonprefix(options.routeFiles)duarouterOutput = prefix + '.rerouted.rou.xml'
duarouterAltOutput = prefix + '.rerouted.rou.alt.xml'Regards,AlejandroEl lun, 15 nov 2021 a las 14:22, Jakob Erdmann (<namdre.sumo@xxxxxxxxx>) escribió: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 toolregards,Jakob_______________________________________________Am Sa., 13.

Quitting (on error).When I introduce the flows as input (option -F flows.xml), the errors change to the following:Error: The route '-226701455_219967849.qPKW.0' for flow '-226701455_219967849.qPKW.0' is not known. (and the error repeats for every flow defined in the flows.xml file).What I am missing here? Is it not possible to run duaIterate.py using the flowrouter.py output as routes/flows data?
