The provision of traffic progression along an arterial street has long been accepted as a desirable traffic control objective to improve the level of service. Bandwidth maximization is often used to optimize progression. A new scheme optimizes two circular phasing sequences in addition to those available in existing bendwidth maximizing programs. The new circular sequences, having the form main1-cross1-main2-cross2, can be clockwise or counterclockwise. The maxband 89t program uses this enhanced optimization capability to find maximumprogression bands on an arterial. This scheme expands the arterial formulation used in maxband 86. It uses the mixed-integer linear programming method for optimizing progression bandwidth. Experimental results for some cases show that the new formulation can produce wider progression bands on an arterial than those of the maxband 86 formulation.
