Joint optimization traffic signal control for an urban arterial road

This paper considers the optimal traffic signal setting for an urban arterial road. By introducing the concepts of synchronization rate and non-synchronization degree, a mathematical model is constructed and an optimization problem is posed. Then, a new iterative algorithm is developed to solve this optimal traffic control signal setting problem. Convergence properties for this iterative algorithm are established. Finally, a numerical example is solved to illustrate the effectiveness of the method.

On Geometrically Uniform Signal Sets and Signal Sets Matched to Groups

H.-A. Loeliger [3] proved that the concepts of the geometrically uniform signal set and the signal set matched to a group coincide when the signal set is finite. In the present note we show that these two concepts also coincide even when the signal set is infinite.
