What is the advantage in running a Multiple-Period analysis in Signals?
The main reason to using a multiple-period analysis is to model the unmet demand that may exist from one 15-minute period to the next in oversaturated conditions. This analysis will estimate the residual queues for each period and use them as the initial queues for the subsequent period for each lane group. This will allow for a more accurate computation of additional delays (d3) attributable to these queues for the overall analysis period. Another advantage to running a multiple-period analysis for any situation (including undersaturated conditions) is to overcome the dilemma in using the appropriate 15-minute period versus a peak-hour factor (PHF) that could vary among movements and periods.
