Construction zone detection using a plurality of information sources
First Claim
1. A method, comprising:
- receiving map information related to a prior map of a road of travel of a vehicle, wherein the map information includes road traffic sign information that indicates locations and types of traffic signs that existed on the road;
detecting, by a computing device using one or more sensors coupled to the vehicle, a traffic sign, and determining that the traffic sign is missing from the map information;
in response to at least determining that the detected traffic sign is missing from the map information determining, using the computing device, a likelihood of existence of a construction zone on the road;
in response to the likelihood exceeding a threshold likelihood, detecting one or more construction zone objects;
determining a severity of road changes based on a number and locations of the one or more construction zone objects; and
providing, by the computing device, instructions to control the vehicle based on the likelihood and the severity of road changes.

Abstract
Methods and systems for detection of a construction zone using information from a plurality of sources are described. In an example, a computing device, configured to control the vehicle, may be configured to receive information, from a plurality of sources, relating to detection of a construction zone on the road on which the vehicle is travelling. Also, the computing device may be configured to determine a likelihood of existence of the construction zone on the road, based on the information. Further the computing device may be configured to modify a control strategy associated with a driving behavior of the vehicle, based on the likelihood; and control the vehicle based on the modified control strategy.

9. A non-transitory computer readable medium having stored thereon instructions that, when executed by a computing device, cause the computing device to perform functions comprising:
-
receiving map information related to a prior map of a road of travel of a vehicle, wherein the map information includes road traffic sign information that indicates locations and types of traffic signs that existed on the road; detecting, using one or more sensors coupled to the vehicle, a traffic sign, and determining that the traffic sign is missing from the map information; in response to at least determining that the detected traffic sign is missing from the map information determining a likelihood of existence of a construction zone on the road; in response to the likelihood exceeding a threshold likelihood, detecting one or more construction zone objects; determining a severity of road changes based on a number and locations of the one or more construction zone objects; and controlling the vehicle based on the likelihood and the severity of road changes. - View Dependent Claims (10, 11)

12. A control system for a vehicle, comprising:
-
one or more sensors coupled to the vehicle; one or more processors in communication with the one or more sensors; and memory configured to store instructions, that when executed by the one or more processors, cause the control system to perform functions comprising; receiving map information related to a prior map of a road of travel of a vehicle, wherein the map information includes road traffic sign information that indicates locations and types of traffic signs that existed on the road; detecting, using one or more sensors coupled to the vehicle, a traffic sign, and determining that the traffic sign is missing from the map information; in response to at least determining that the detected traffic sign is missing from the map information, determining a likelihood of existence of a construction zone on the road; in response to the likelihood exceeding a threshold likelihood, detecting one or more construction zone objects; determining a severity of road changes based on a number and locations of the one or more construction zone objects; and controlling the vehicle based on the likelihood and the severity of road changes. - View Dependent Claims (13, 14, 15)
