Abstract :
The calculation of delays at an intersection is an old problem that has been studied and solved by many researchers. This paper reanalyzes the problem by using a Markov chain model for the probability distribution of queue length. From the dynamics of the expectation value of the queue length, the authors derive a formula for the delay in fixed time traffic control. The effect of the overflow queue is made explicit. The result is a new formula, but even more important, a clear understanding of the role of the overflow queue
