thks and a little confusion weight file generated by sumo is the simulation result one simulation's result can be another simulation's input?
maybe the truth is simulation's input weight file is different with simulation's output weight file, they just have the same format and the custom weight file's edge element should only contain weight attribute, other attribute like density , speed ... are simulation result, they are invalid in custom edge weight file right? then i should wirite custom weight file by hand? is there some tools can help me do this . or i should use a simulation's result and delete ohtere invalid attribute just left the weight attribute look forward to your reply :) 发自网易邮箱大师 在2017年12月06日 22:13，Jakob Erdmann<mailto:[email protected]> 写道： 1) yes. However, sumo can also load incomplete trip/flow files directly (routing is then performed in the simulation) 2) yes 3) sumo If you do this iteratively you can compute the dynamic user equilibrium: http://sumo.dlr.de/wiki/Demand/Dynamic_User_Assignment 2017-12-06 6:51 GMT+01:00 杜 伟强 <[email protected]<mailto:[email protected]>>: thanks for your answer there are still some questions 1。 duarouter use incomplete trip/flow file ，net xml file ，weight file and additional file to generate complete route file 。 right？ 2 weight is generated from additional file with <edgedate>/<lanedata> element。 right？ 3 if 2 is right ， which application can use additional file to generate weight file thank you for help me ：） 发自网易邮箱大师 在2017年12月06日 04:16，Jakob Erdmann<mailto:[email protected]> 写道： Hello, 1) the travel time of an edge usually equals it's length divided by it's speed limit. The actual speed of any one vehicle may differ from the speed limit and thus the travel time may be different as well. See http://sumo.dlr.de/wiki/Simulation/VehicleSpeed 2) the 'stored travel time' of a lane you can see in sumo-gui, is a way to customized the travel time values that are used when re-routing vehicles within the simulation (http://sumo.dlr.de/wiki/Simulation/Routing). 3) see http://sumo.dlr.de/wiki/Demand/Shortest_or_Optimal_Path_Routing#Custom_edge_weights and http://sumo.dlr.de/wiki/SUMO#Format_of_additional_files regards, Jakob 2017-12-05 15:01 GMT+01:00 杜 伟强 <[email protected]<mailto:[email protected]>>: Hello : I’m getting trouble in travel time. 1 .what is the definition of travel time 2. I see travel these words in user doc Usually, each road within a simulation has an assigned travel time based on its length and allowed speed. but when I right click show parameter in sumo-gui,every lane’s travel time is -1 3. how to set travel time in .xml file? I find this parameter is set in weight file. But maybe weight file is generate by additional file. How to generate weight file. Is there an example file? What is the relationship between weight file and additional file I was bothered by these problem so long time. Any one can help me ?
