The invention discloses a road congestion status calculating method based on geomagnetic devices. The method comprises following steps of: laying geomagnetic devices in each lane on a road, wherein the geomagnetic devices acquire vehicle state information on the road in real time and transmit the vehicle state information to a database in a wireless communication manner; calculating, by using a server, a road-occupying ratio of the road within a certain time according to the vehicle state information received by the database; comparing the road-occupying ratio of the road within the certain time with a congestion index Y and a unblocked index C, and obtaining a road status according to a comparison result; and releasing the obtained road status in a guide screen which displays pass states in different colors. The method may fast and accurately acquire the congestion status.
