Abstract: The disclosure provides a method for determining an intersection missing traffic restriction information and an electronic device. The method includes: obtaining trajectory information corresponding to the intersection; determining a traffic anomaly occurring at the intersection based on the trajectory information; obtaining lane line information of a road section connected by the intersection; and determining the intersection missing traffic restriction information based on the lane line information.
