The invention discloses an expressway tunnel accident judgment method, system, device and medium, a plurality of magnetic sensors are arranged on a target lane of a tunnel at equal intervals along the driving direction of the tunnel, and the method comprises the following steps: determining a first state of each magnetic sensor in a current time period according to first geomagnetic data corresponding to each magnetic sensor in the current time period; according to the first state of each magnetic sensor in the current time period, constructing a first vehicle distribution matrix corresponding to the target lane in the current time period; acquiring a second vehicle distribution matrix corresponding to the target lane in the second time period and a third vehicle distribution matrix corresponding to the target lane in the third time period; and according to the similarity among the first vehicle distribution matrix, the second vehicle distribution matrix and the third vehicle distribution matrix, determining
