ROUTE PLANNING SYSTEM AND METHODOLOGY WHICH ACCOUNT FOR SAFETY FACTORS

摘要

A system and methodology that provides travel routes that minimize crash risk and add a safety factor to the determination of preferred routes of travel. Multiple elements of safety are considered in determining preferred routes of travel. This may include consideration of the user's physiological and/or psychological state during the time of travel. Alternatively or in addition, required driving maneuvers, roadway crash histories, demographic data and/or secondary task engagement while driving by the user may be considered in determining the optimal route of travel given the foregoing safety factors.

主权项

1. A navigation system for providing travel routes that maximize the likelihood of safe travel by a driver of a vehicle, the system comprising:
at least one parameter-sensing system including at least one of:
an in-vehicle-sensory-distraction (IVSD) parameter-sensing system;an in-vehicle secondary-task-engagement (IVSTE) parameter-sensing system; anda driver-emotion-suggestive vehicular (DESV) parameter-sensing system; a driver-interface; and one or more processors configured to execute computer program modules, the computer program modules comprising:
a geographic route planning module configured to generate at least one possible routes of travel from a starting location to a destination location;a safety based refinement module configured to assess each of said at least one possible routes for at least one safety factor, associated with each of said at least one possible routes of travel, based on information from the at least one parameter-sensing system; andan initial route generation module configured to interact with the driver via the driver-interface and thereby present said at least one possible routes and the at least one corresponding assessed safety factors, respectively, and receive a selection therefrom as an initial route to be traversed.
