Hi all, I need a custom SUMO Weight File that consist of SUMO Edge ID and Traveltime (Length / Speed) in a separate xml file so that I can use --weight-files attribute with the possibility to add more other custom weight attributes.
I also need to use --weight-files attribute for all simulation, so as to compare a static no rerouting as well as dynamic rerouting by TraCI later. I have tried the following: 1. Declare a description file, run the simulation once (And hence, failed to meet my requirements). http://sumo.dlr.de/wiki/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures However, the CSV format generated from XML tools (xml2csv) cannot be directly convert back to XML again using csv2xml. This is because I need a XSD file. http://sumo.dlr.de/wiki/Tools/Xml 1. Tried using sumolib directly with the following codes: net = sumolib.net.readNet('Network.net.xml') edges = net.getEdges() i = 0 csvWeight = "edge_id;travelTime\n" while (i < len(edges)): #Get the edge item for edges in XML format that is converted to String: <edge id="x" from="y" to ="z"> edge_item = str(edges[i]) #Extract only the id part, we want only edge id. edge_id = edge_item.split("\"")[1] #Get the specific edge currentEdge = net.getEdge(edge_id) length = currentEdge.getLength() speed = currentEdge.getSpeed() minTime = length / speed csvWeight += str.format("{0};{1}\n", edge_id, minTime) i+= 1 try: resultFile = open('weight.csv', "w") #Which will overwrite existing file. resultFile.write(csvWeight) resultFile.close() #Always remember to close a file after I/O operation. except IOError as e: #Prints error message due to write error (Typically due to lack of permissions). print(str.format("Error occurred: {0}", str(e))) I still face the same XSD file issue if I used: python csv2xml.py -x edges_file.xsd input.csv http://sumo.dlr.de/wiki/XMLValidation#Adding_a_schema_declaration Because it says it requires 3 attributes, while I provided only 2. csv2xml does not work if I do not declare a XSD. So what should I do to get a CSV weight file that is compatible with csv2xml for SUMO's use?
