The invention provides a rail transit line monitoring sensor layout optimization method and system oriented to vehicle-rail cooperation, and belongs to the technical field of rail transit system monitoring optimization. Based on the sensing accuracy of the monitoring sensor sensing algorithm to the abnormal event, determining the combined sensing accuracy of the monitoring sensor to the abnormal event under the vehicle-track cooperation; according to the combined sensing accuracy of the monitoring sensors on the abnormal events under the vehicle-rail cooperation, the arrangement distance and the arrangement number of the trackside monitoring sensors are calculated; and optimizing trackside monitoring sensors close to the area junction according to the maximum monitoring sensor layout spacing allowed by the sensing accuracy threshold. According to the method, factors such as sensing boundaries, sensing accuracy and layout cost of the monitoring sensors are fully considered, and the layout cost of the monitoring sensors is effectively reduced on the premise of ensuring high sensing accuracy of the monitoring sensors to line abnormal events aiming at the phenomenon of resource waste caused by the fact that the trackside monitoring sensors at the region junction are too close; the economy is higher.
