An enhanced navigation system allowing navigation route and destination planning according to user-specified criteria for the emotion state of persons along the route, at the destination, or both. The enhancement is accomplished by receiving a set of human emotion metrics corresponding to one or more parts of a navigation plan; determining if the human emotion metrics meet one or more user-specified criteria; responsive to not meeting the criteria, determining an alternate navigation plan until the user-specified criteria are met; and responsive to the criteria being met, presenting the navigation plan to the user for laying into a navigation system, and optionally during execution of the navigation plan updating the received human emotion metrics; repeating the determination against the user-specified criteria; and repeating the steps of determining an alternate navigation plan and presentation to a user responsive to the updated human emotion metrics not meeting the user-specified criteria.
