1. A controller of a vehicle, comprising:
a communication interface configured to receive map data; and
processing circuitry configured to control the vehicle to navigate an environment and, while navigating the environment, to cause the vehicle to:
determine road condition data based on the map data;
determine road segments of a route based on the map data;
assign quality weighting factors corresponding to respective road qualities of the road segments to the road segments of the route, the quality weighting factors being assigned based on a driving event type of one or more driving events occurring within the road segments,
wherein the one or more driving events are determined based on data from a sensor of the vehicle and/or a sensor within or attached to the vehicle that is communicatively coupled to the controller; and
calculate a driver score based on the determined road condition data and the quality weighting factors by assigning, to each of the one or more driving events occurring within the road segments based on the driving event type, (i) one of a set of negative quality weighting factors that are less than a predetermined quality weighting factor, which yields a negative contribution to the driver score, and (ii) one of a set of positive quality weighting factors that are greater than a predetermined quality weighting factor, which yields a positive contribution to the driver score,
wherein the communication interface is further configured, while the vehicle is navigating the environment, to periodically receive or periodically transmit data that is used to determine the driver score.
