| The objective of this study is to analyze the behavior of offsets between traffic signal subnetworks. If different cycle lengths are used for adjacent subnetworks, the relative timing between the subnetworks will deviate from the original setup. A generalized mathematical model is developed, which demonstrates the cyclic timing patterns of offsets between subnetworks with different cycle lengths. The offset cycle time is equal to the Least Common Multiple (LCM) of the cycle lengths of the adjacent subnetworks. A TRAF-NETSIM model is used to examine how the cyclic behavior of offsets should be considering in timing the subnetworks, and in reconciling different offset requirements between more than two subnetworks. |
