Titel
Magnetic traffic detection using fluxgate sensors
Abstract
Modern individual vehicle traffic is often disturbed by traffic stockings. The expected increase of traffic on the roads cannot be handled by building further lanes or completely new roads. A more intelligent alternative is the control of the traffic by remote controlled traffic signs and broadcasting of actual traffic information. For this reason highly reliable traffic detection systems for a reasonable price of installation and maintenance are required. A new promising approach is the magnetic traffic detection that uses the influence of the vehicles steel mass on the earth magnetic field. A prototype of this system has been realized which is capable to measure the traffic from an overhead position through a distance of at least six meters. First measurements show the very good performance of the system. Further work is intended toward a more detailed classification of the vehicles and alternative sensor mounting under the street surface.
