A green wave band model considering variable queue clearance time

The variable queue clearance time model is derived by analyzing the relation between the adjacent upstream intersection´s departure traffic flow pattern and the offset time. To take the variable queue clearance time into consideration, the proposed revised MAXBAND model combines the variable queue clearance time model and traditional MAXBAND model. After the process of variant substitute, the revised MAXBAND model can still be solved by classical MILP solution method. An example with two intersections is given, and the results of the proposed model and simulation indicate that, the revised model is better than traditional model in arterial control since the consideration of variable queue clearance time. In the example arterial, the revised model increases the effective green-wave bandwidth by 31.6%, and decreases the average arterial delay by 12.6%.
