1. A method, comprising:
receiving, from a camera coupled to a vehicle, visual data representing an image captured by the camera;
processing the visual data with a neural network, the neural network comprising:
a curve determination branch,
an object detection branch, and
a common trunk, the common trunk configured to perform one or more processing operations on the visual data to produce a common trunk output;
processing the common trunk output with the curve determination branch of the neural network to produce a curve determination data; and
determining a location of a traffic boundary based on the curve determination data.
