  • classifying the vehicle detecting devices forming the sensor network into a plurality of groups by the system;

    determining a current signal state based on traffic signal information provided from the traffic signal controller by the system;

    generating first activation control information that allows the vehicle detecting device to activate or deactivate a sensing operation of detecting vehicles for each group by the system, based on the current signal state of the determined traffic signal controller and vehicle incoming and outgoing information provided from the vehicle detecting devices of each group; and

    transmitting the first activation control information including an instruction code indicating the activation or deactivation and an activated or no-activated starting time and duration for each group by the system.
