1. A method for construction area alert, the method comprises:
receiving by a vehicle computerized system, construction area indicators, each construction area indicator associated with a construction area situation of corresponding construction area objects within an environment of the constructed area situation, wherein the construction area indicator is selected based on occurrence information, normalized across a defined period of time, regarding an appearance, at a first probability, of the corresponding construction area objects within the environment of the construction area situation and an appearance, at a second probability, of the corresponding construction area objects outside the construction area situation, where the second probability is lower than the first probability by an amount that is determined based on a tradeoff between false positive identification of the construction area situation and false negative identification of the construction area situation;
obtaining sensed information regarding an environment of the vehicle;
continuously processing the sensed information with respect to the received construction area indicators, wherein the processing comprises searching for a construction area indicator in the environment of the vehicle;
autonomously determining, when finding a construction area identifier, that the vehicle is driving towards a construction area or is within the construction area; and
generating an alert when determining that the vehicle is driving towards the construction area or is within the construction area.
