The invention discloses a trunk line self-optimizing signal control method based on terrestrial magnetism, and mainly relates to the field of arterial road intersection signal optimization control. Through the comprehensive application of novel geomagnetic vehicle detection equipment, the method achieves the dynamic detection and signal optimization processing of traffic conditions of a plurality of intersections on a trunk line. The method comprises the steps: geomagnetic equipment installation; data collection and communication; the processing and calculation of a trunk line self-optimizing signal; and the publishing and control of a signal instruction. The invention also provides a trunk line self-optimizing signal control device based on terrestrial magnetism. The method and device employ the technology of two-dimensional active-type terrestrial magnetism, can achieve the accurate detection of the real-time traffic conditions of a plurality of intersections of the trunk line, makes an optimized signal control scheme, provides a real-time decision and emergency processing information for the traffic management and control, and improves the operation efficiency and service level of the traffic of the trunk line.
