1. A method of recognizing a road hazard area or a road construction area on a roadway along which a vehicle is driving, comprising the steps:

  • detecting an actual traffic light system along the roadway, from environment data produced by at least one environment sensor of the vehicle,determining actual positional data of the actual traffic light system, from the environment data,determining an environment scenario by classifying an environment configuration represented by features detected in the environment data,determining a reference model pertaining to the environment scenario, wherein the reference model indicates whether an expected traffic light system exists in the reference model, and when the expected traffic light system does exist in the reference model then the reference model provides reference positional data regarding an expected position of the expected traffic light system, andwhen the reference model does not include the expected traffic light system or indicates that the reference positional data of the expected traffic light system differs from the actual positional data of the actual traffic light system, then based at least thereon as a prerequisite, concluding that the actual traffic light system is a temporary traffic light system located at and identifying a road hazard area or a road construction area.
