The invention provides a determining method and system for construction enclosure road, and the method comprises the steps: obtaining the road condition data of one road element; judging whether the difference between a mean historical peak traffic vehicle flow and a current peak traffic vehicle flow is greater than a peak traffic vehicle flow threshold value or not; adding one to an initial suspect degree of the road element if the difference between the mean historical peak traffic vehicle flow and the current peak traffic vehicle flow is greater than the peak traffic vehicle flow threshold value; judging whether the difference between a mean historical peak traffic vehicle speed and a current peak traffic vehicle speed is greater than a peak traffic vehicle speed threshold value or not; adding one to an initial suspect degree of the road element if the difference between the mean historical peak traffic vehicle speed and the current peak traffic vehicle speed is greater than the peak traffic vehicle speed threshold value; judging whether the suspect degree of the construction enclosure of the road element is greater than or equal to a suspect degree threshold value or not; determining the road element to be a construction enclosure road element if the suspect degree of the construction enclosure of the road element is greater than or equal to the suspect degree threshold value; and updating the road condition information of the construction enclosure road element into an electronic map. The method and system can improve the accuracy of road condition judgment while guaranteeing the timely updating of the road condition of the electronic map.
