For data collection requirements of the city road section traffic flow , this paper puts forward the road sec-tion traffic data collection plan based on geomagnetism detection technology. In Accordance with relative require-ments, combined with the theory of geomagnetism detection technology, a traffic data collection system framework is built and verified to be feasible in the concrete implementation. The implementation effect shows that the geomag-netic detection technology, as a new road section traffic detection technology, is easy for installation and mainte-nance, has high detection sensitivity and accurate detection of time occupancy and can be applied in many parameter detection. Thus, this technology is appropriate to city road section traffic flow data collection.
