Abstract:
In this paper we consider an intersection of two two-way streets with
controllable traffic lights on each corner. We construct a model that
describes the evolution of the queue lengths (as continuous variables)
in each lane as a function of time. We discuss how optimal and
suboptimal traffic light switching schemes (with possibly variable
cycle lengths) for this system can be determined. We show that for a
special class of objective functions, an optimal traffic light
switching scheme can be computed very efficiently. The main difference
of the approach presented in this paper and most other existing
methods is that we allow the green-amber-red cycle time to vary from
one cycle to another.
