An augmented road line display system that includes one or more sensors installed on a vehicle, one or more external databases, and processing circuitry. The processing circuitry is configured to receive inputs from the one or more databases, sensors of the vehicle, and a sub-system of the vehicle, build and validate a road line model to detect or predict a road line based on the inputs received, determine environmental conditions based on the inputs from one or more of the databases, and a sub-system of the vehicle, assign weights to the inputs received based on the environmental conditions to generate weighted inputs, and execute the road line model to determine the road line based on the weighted inputs.
