Optimization Of Signal Timing Transition Period
Author(s)
R. Mussa & M.F. Selekwa
Abstract
This paper reports on the development of a transition procedure based on the
quadratic optimization method. The procedure is aimed at reducing disutility
measures to motorists during the transition period. The transition is modeled as
a linear dynamic process, and the disutility measures are modeled as the sum of
squares of the deviations of the coordination parameters—that is, cycle length,
phase split, and offset—from the optimal values during the transition. Optimal
control techniques are used to determine the step size and optimal number of
steps necessary to complete the transition with minimum disruption to traffic
flow. The proposed transition procedure does not go beyond the current and the
target cycle lengths thus eliminating the need for the user to specify minimum
and maximum values of splits and cycle lengths to accommodate pedestrians and
other local intersection
