Data Input. The consultant shall establish a base network utilizing computer models such as Synchro, PASSER, TRANSYT-7F, TEAPAC etc. for the study time periods (i.e., morning, midday, p.m., etc.). The typical data used in the model include lane geometry, link speeds and distances, phase numbering, left- and right-turn phasing, existing signal timing (i.e., yellow and all-red intervals, pedestrian walk and flashing don’t walk intervals, minimum green, and detector settings), controller type, and coordinated reference phases. Field observations should be compared with the traffic operation results for each time period in the model. A review of the calibrated model shall be performed prior to moving forward with the timing plan development analysis.
