The report presented methodology for comparing arterial corridors in terms of mobility-based performance measures, with the goal of establishing a process for easily identifying corridors in need of signal re-timing or adaptive signal control.
The evaluation first identified the number of "abnormal" traffic days in a year to characterize the cost-effectiveness of an adaptive system. Then, for "normal" days, it compared volume-normalized performance among corridors to identify problematic segments. This analysis was performed for a total of 13 arterial corridors: 12 around Des Moines, and 1 in Omaha.
