If you are planning a road trip, it is essential that you use a route planner. When you use a route planner, you can input several desired destinations, and the route planner will create a route for you that will take you to all of your desired destinations. Often, you can tell the route planner whether you want to avoid tolls or highways, if these things are important to you. When you use a route planner, you should keep in mind that you will probably end up driving more miles than are actually calculated because you will want to explore the areas a bit. You may drive several miles off of the route to go to a restaurant that locals rave about.

It is better to use a Garmin or GPS to construct a route planner because the Garmin or GPS automatically finds the best and quickest routes. Most Garmin's or GPS tools also keep into account traffic when figuring the best route. Traditional maps take more time to use and do not give turn by turn directions. Usually traditional maps require two people, one driving, and one using the map, to be most effective.

The AA route planner is useful when a person that will be traveling wants to avoid motorways, tolls, or other congestion points. A very useful tool provided by the AA route planner is the "Via" route option, allowing travelers to use a route through a particular location, say for tourism or sight-seeing, or to avoid a certain place by using a "via" route away from that location.
To use the AA Route planner one can input the address, (or even a city or point of interest), from which they are departing and then also the address to which they are headed, and the AA route planner can provide directions.
As for which one is the best, there is no definite answer, because multi-site route planning is the basic function of a route planner, and most of them have perfect algorithms on the market! You can choose according to your needs, for example, if you have a 50% repetition rate of daily delivery locations, you can choose to use Loop Route Planner as it not only supports address book but also reuse historical delivery locations to quickly create new routes to avoid wasting time in order to "save time".
If you live in Great Britain, Europe, or Ireland, the AA Route Planner is free and is easy to use. The planner does not include the Unitd States.
