1. A computer aided routing system (CARS) comprising:

  • a digital computer having a computer display;

    a map database providing a set of electronic maps for presentation on the computer display;

    said electronic maps depicting transportation routes having identified waypoints including route intersections at geographical locations along the transportation routes, said identified waypoints depicted on the electronic maps being identified in the computer by coordinate locations of a selected geographical coordinate system;

    a CARS database of geographically locatable points of interest (POIs) identified by coordinate locations in said geographical coordinate system, said POIs being organized into a plurality of types for user selection of POIs by type, said POI types comprising overlays of the CARS database for display over the electronic maps on the computer display;

    CARS software constructed for user travel planning using said electronic maps presented on the computer display, said CARS software permitting user selection of a travel origin, travel destination, and desired waypoints between the travel origin and travel destination, said CARS software calculating, delineating, and displaying a travel route between the travel origin and travel destination via the selected waypoints according to user choice of the shortest travel route, quickest travel route, or user selected preferred travel route;

    said CARS software permitting user selection of a region of interest along the user defined travel route, said region of interest having user specified dimensions and permitting user selection of specified POI types within said region of interest and user selection of particular POIs from the selected types within the region of interest, said region of interest being identified in the computer by coordinate locations of said geographical coordinate system;

    said CARS database comprising travel information selected from the group consisting of graphics, photos, videos, animations, audio information, and text information about POIs of the CARS database and about selected transportation routes and waypoints of the electronic maps;

    said CARS software being constructed to present a user customized travelog for preview on the computer display of the user defined travel route including said travel information in the CARS database on the transportation routes and waypoints of the electronic maps and the selected POIs of the CARS database in the user defined region of interest along the travel route.
