Currently, the congestion KPI takes the average delay ratio for each vehicle by mode across all links. However, the links are different lengths, and therefore we cannot treat all links as equal. We'd like the Congestion KPI to be weighted by the length of each link. When we include the length of the link and average across all vehicles for that mode, this essentially weights the KPI by veh-km for each mode.
