Hello there, I would like to collect some stats about the edges such as length, mean speed, mean density,....... I know a few approaches, and I think the second one is the easiest/fastest approach but I have some difficulty to make it practical: 1-using inductive loop detectors-> use additional file and create a loop for each lane-> time consuming, is there any existing script for this? 2- use MeanData-> I am not sure how I can instantiate this (http://sumo.dlr.de/wiki/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures), shall it be done through additional file (Is there any example for using this method)? what does id mean here? | id | id (string) | The id of this set of measurements. This user-defined id is needed for differentiating between multiple sets of measurements in a single output file. |
Wiki says the id of measurement, so what does this actually mean? where and how shall I define the measurement formula? Is not this the edge id?How many output it generates? one for each id? I need to use mpl_dump_onNet.py for visulizing these outputs? Is there any existing script that can read these output? 3. Use --full-output -> makes the simulation very slow 4. TracCI-> slow down the simulation, I may just use this to get the length of all edges and save them in my database, if I cannot get the length in any other way. I would be very grateful if you could advise. Many thanksMohsen
