Access free online map-creating websites such as Google Maps or MapQuest. The left-hand quarter of the screen is where you enter your details and make selections, while the rest of the screen shows the map, which changes according to your choices.
Click on the option to "Get Directions." This will bring up two boxes, "A" and "B," in which you can put your starting place, "A," and your destination, "B." If you click on the option to add more stopping points, or destinations, you will be given more boxes to fill out. The boxes are filled from top to bottom with the corresponding journey points, from start to finish. The boxes in the middle are for places where you think you will want to stop for fuel, toilet breaks, meals or accommodation, depending on the length of the expedition. Some software may even show you where fuel and accommodation is available along your route.
Add additional refinements to your plan by clicking on the link for "Further Options." Depending on the mapping software you are using you will be able to make choices about taking main roads or scenic routes and it may tell you things to avoid, like toll roads, perhaps. An optimum route for you, based on your selections, will be shown, or you may be given a couple of routes to choose from which fit your requirements. An estimated journey time will calculated for you and, if you want a shorter drive, try inputting different variables such as allowing the use of main roads rather than country lanes, for instance.
Print your map which will highlight the route you have opted for. Route descriptions will also be generated, which a passenger can read out for you. Google Maps and MapQuest have several selection boxes at the top of their maps including one for up-to-date traffic reports which, if available, can show the latest traffic conditions on your map up to within five minutes. Have a look at this before you embark on your road trip.
