I have been trying to understand how the average speed is calculated in edge-based traffic measures. I know it is space-mean speed but I am trying to aggregate data for multiple edges.
I first generated average speed of two edges using edges="" and aggregate="True" method, then I generated average speed of the two edges separately. Now, I have tried arithmetic mean, harmonic mean, weighted average by numbers but cannot get the value equal to the aggregated value given by SUMO.
Kindly suggest in what way can I manually aggregate the average speed data so as to get same value as when being done by aggregating directly through SUMO.
Thanks and regards,
