Method for determining upper and lower limit values of possible traffic density involves recording aggregated traffic density data at defined intervals and switching times of light signal system

摘要

Method involves recording aggregated traffic density data at defined intervals and switching times of light signal system. Release times of signal group assigned to detector, saturated traffic density of this signal group and the upper and lower limit values for possible traffic density are determined. Detected value with respect to the limit values is examined and if necessary this value is corrected.
