1. A method, comprising: receiving, at a computing device configured to control a vehicle, from a light detection and ranging (LIDAR) sensor coupled to the computing device, LIDAR-based information relating to a three-dimensional (3D) point cloud of a road on which the vehicle is travelling, wherein the 3D point cloud comprises points corresponding to light emitted from the LIDAR and reflected from one or more objects on the road; selecting, using the computing device, a portion of the 3D point cloud representing an area within a predetermined threshold distance from a surface of the road; identifying one or more construction zone objects in the selected portion; determining, using the computing device, a number and locations of the one or more construction zone objects; determining, using the computing device, a likelihood of existence of a construction zone based on the number and the locations of the one or more construction zone objects; in response to the likelihood exceeding a threshold likelihood, determining a severity of road changes due to the existence of the construction zone based on the number and the locations of the one or more construction zone objects; modifying, using the computing device, a control strategy associated with a driving behavior of the vehicle based on the likelihood of the existence of the construction zone on the road and the severity of the road changes; and controlling, using the computing device, the vehicle based on the modified control strategy.
