Operação de sinais de tráfego.

Abstract

In the traffic network the conflict points are the ones which most show problems. This is because the continuous supply of flows which cross must be warranted by a type of control that minimizes the delay, the queue length, the accidents rates, etc, that appears with the operation of an intersection. Accordingly, the purpose of this research is to make a comparative study between a politic of manual signals control and another optimized by empiric model developed by Webster and Cobbe. In this work were elaborated models of simulation of signal operations and developed computer programs which permit to find the best cycle length of any semaphore, by a simple alteration in the input datas.
