文摘

Controlling intensive traffic flow differs radically from free flows control, while management of transport networks can be complicated due to inability to locate excessive density of flows within a single intersection. This paper applies a model of cyclic balance of transportation demand and supply in order to find out an optimum traffic light control mode. The traffic light control mode is determined by challenging the issue of maximization of traffic intensity control subject to restrictions on the volumes of arriving and leaving flows and the queue length at respective sets of links. A feature of the proposed method is a differentiated approach to transportation links. It suggests that excess traffic demand in the control zone is localized on a set of links characterized by presence of a controllable line.
