Abstract
An example method and apparatus are disclosed. An infrastructure device is mounted to construction equipment located at a road construction zone with an input view of a predefined area of a road. The device may receive sensor data of road users and the road construction zone. Responsive to the sensor data, the device classifies objects as construction lane markers and determines coordinates of the construction lane markers. Using map data indicative of drivable lane boundaries of the road construction zone, the device determines whether the construction lane markers are within the drivable lane boundaries. Responsive to the determination, temporary lane boundaries for the construction zone are computed and transmitted in a data set to at least one autonomous vehicle.
