Route planning software

Route planning software is a computer software program designed to plan a (optimal) route between two geographical locations using a journey planner specialized for road networks for the purposes of providing automotive navigation. It can typically provide a list of places one will pass by, with crossroads and directions that must be followed, road numbers, distances, etc. It also usually provides an interactive map with a suggested route marked on it. Many online mapping websites offer road route planning as an additional feature of their mapping functions. Applications can sometimes also calculate the journey time and cost, and some also display points of interest along the route.

Distribution companies may incorporate route planning software into their fleet management systems to optimize route efficiency. A route planning setup for distribution companies will often include GPS tracking capability and advanced reporting features which enable dispatchers to prevent unplanned stops, reduce mileage, and plan more fuel-efficient routes.
