However, municipalities and utility providers may not be able to provide accurate and / or timely updates on the location of construction areas
When encountering a new construction zone, the AV may not have enough information to adjust its driving path to avoid the construction zone and may thus become ineffective

A method for construction zone detection is provided. The method includes automatically capturing, via an onboard optical sensor on a vehicle, a plurality of images of a road along a path traveled bythe vehicle; transmitting captured images to an off-board datacenter; identifying, by a processor in the vehicle, images that provide evidence of the existence of a construction zone on the road; transmitting, to the datacenter, location data identifying the location of the construction zone; and transmitting, to the datacenter, data identifying the frames of image data that provide evidence of the existence of the construction zone. A mapper can review the location data and the image data to confirm the existence of a construction zone and cause the location of the construction zone to be added to a listing of active construction zones, wherein the listing can be provided to autonomous vehicles.
Description
Background technique [0001] The present invention relates generally to systems and methods for detecting construction zones, and more particularly to systems and methods utilizing crowdsourcing to detect construction zones. [0002] Autonomous vehicles (AVs) may not navigate optimally when encountering construction areas. As a result, the AV may attempt to generate a route that avoids construction areas. Construction areas may not be well documented. Municipalities and utility providers may be relied upon to provide location information about construction areas. However, municipalities and utility providers may not be able to provide accurate and / or timely updated information regarding the location of construction areas. When encountering a new construction zone, the AV may not have enough information to adjust its driving path to avoid the construction zone, and may thus become ineffective. [0003] Therefore, there is a need for systems and methods that enable more accur...
