Abstract

A route-determination module (RDM) is provided, with the RDM having as input one or more cognitive preferences of a traveler. Further, the RDM receives input on a current or a forecasted cognitive state of the traveler, along with the cognitive load associated with one or more potential routes for traveling to a destination. A recommended route is determined based on the preference(s), state, and/or cognitive load.

Claims

1. A method comprising:

receiving, by a computer, a request from a driver for a recommended trip route to drive a vehicle from a start location to a destination location;

receiving, by the computer, a set of cognitive preferences of a driver from a GPS device including a target cognitive state for the driver;

receiving, by the computer, a current cognitive state of the driver, the current cognitive state being based at least in part on a sleep record of the driver for a period ending at the time the current cognitive state is received;

identifying, by the computer, a set of trip routes from the start location to the destination location;

defining, by the computer, a state transition model of cognitive states for the driver, the state transition model being programmable by the driver for determining the recommended trip route from the set of trip routes based on a cognitive state transition from the current cognitive state to the target cognitive state;

receiving, by the computer, a set of cognitive loads respectively corresponding to the set of trip routes, the set of cognitive loads being based at least in part on a number of complex intersections and a record of aggressive drivers for each trip route of the set of trip routes; and

determining, by the computer, the recommended trip route from the set of trip routes based at least in part on the set of cognitive preferences of the driver, the current cognitive state of the driver, and the cognitive loads of the set of cognitive loads respectively corresponding to the set of trip routes.
