Construction zone sign detection

A non-transitory computer readable medium having stored thereon instructions that, when executed by a computing device of a vehicle, cause the computing device to perform operations comprising:

• receiving, from an image-capture device coupled to the vehicle, an image of a vicinity of a road of travel of the vehicle;
• selecting, from the image, an image portion corresponding to a side of the road;
• detecting a construction zone sign in the image portion;
• determining a type of the construction zone sign;
• detecting one or more construction zone objects on the road;
• determining, based on a number and locations of the one or more construction zone objects, a severity of road changes;
• and
• controlling the vehicle based on (i) the type of the construction zone sign, and (ii) the severity of road changes.

A control system for a vehicle, comprising:

• an image-capture device;
• a computing device in communication with the image-capture device;
• and
• data storage comprising instructions that, when executed by the computing device, cause the control system to perform operations comprising:
• receiving, from an image-capture device coupled to the vehicle, an image of a vicinity of a road of travel of the vehicle,
• selecting, from the image, an image portion corresponding to a side of the road;
• detecting a construction zone sign in the image portion,
• determining a type of the construction zone sign,
• detecting one or more construction zone objects on the road,
• determining, based on a number and locations of the one or more construction zone objects, a severity of road changes, and
