System and method for determining road work zone start location

A system for detecting a road work zone, the system comprising:

• at least one non-transitory memory configured to store computer executable instructions;
• and
• at least one processor configured to execute the computer executable instructions to:
• detect a road object based on sensor data and map data;
• determine a first location associated with the road object based on location of a vehicle capturing the road object at a time of road object sighting and the sensor data;
• based on image data captured by the vehicle at the time of road object sighting, determine a road object type and supplemental information associated with the road object;
• and
• detect the road work zone based on the first location, the road object type, and the supplemental information.

A computer programmable product comprising a non-transitory computer readable medium having stored thereon computer executable instruction which when executed by one or more processors, cause the one or more processors to carry out operations for detecting a road work zone, the operations comprising:

• detecting a road object based on sensor data and map data;
• determining a first location associated with the road object based on location of a vehicle capturing the road object at a time of road object sighting and the sensor data;
• based on image data captured by the vehicle at the time of road object sighting, determining a road object type and supplemental information associated with the road object;
• and
• detecting the road work zone based on the first location, the road object type, and the supplemental information.
