Claim 0:
1. A method for providing explanations in route planning, comprising:
determining a route based on at least two objectives and a user preference with respect to the at least two objectives received from a user,
wherein the user preference corresponds to a prioritization of the at least two objectives,
wherein a second objective of the at least two objectives is constrained to within a slack value of a first objective of the at least two objectives when the user preference indicates that the first objective is of higher priority than the second objective,
wherein the slack value defines a deviation from the first objective to improve the second objective,
wherein the route is determined using the slack value, and
wherein the at least two objectives comprise an urban objective relating to a preference for urban lane segments as opposed to rural lane segments;

controlling an autonomous vehicle to traverse the route;
receiving, from the user, a request for an explanation as to an action along the route; and
providing the explanation to the user, wherein the explanation describes an extent of violating the slack value.
