TRAFFIC-FLOW CONTROL APPARATUS AND METHOD THEREFOR

摘要

The present invention relates to a traffic-flow control apparatus and a method therefor. The traffic-flow control apparatus comprises: a first congestion-degree information-collection unit for collecting first congestion-degree information from a traffic-information-collection device before entrance into an intersection; a second congestion-degree information-collection unit for collecting second congestion-degree information from a sensor provided in a vehicle after entrance into an intersection; a congestion-degree level-setting unit for setting the congestion-degree level of the current intersection on the basis of the collected first congestion-degree information and second congestion-degree information; and a signal-cycle control unit for controlling the signal cycle of an intersection by comparing the set congestion-degree level of the current intersection with the signal-cycle level of the current intersection.
