So I have two lists.
l_2014=[22,27,58,62,75,122]
l_2015=[23,25,60,62,74,124]
Each number inside a list represents the average travel time of a road segment for a year. l_2014 for the year 2014, and l_2015 for the year 2015.
I also have a weight for the usage of these segments.
W=[100,200,150,100,100,70]
My question is how to decide whether the travel time is significantly different from each other collectively. i.e. the network's travel time significantly change from the year before?
What indicators should I use? Can I simply average/weighted average them to see the mean difference?
Thanks!
