Abstract: The disclosed herein is a computer-implemented route planning method which comprises of determining source and destination nodes in a graph data structure based on a route planning query, wherein the graph data structure represents a road network, identifying a plurality of locations on the road network for refilling or recharging of a vehicle, executing an initial graph search on the graph data structure using graph costs based on real-time traffic data, wherein the initial graph search starts at the source node and settles nodes until it stops, computing one or more routes to the destination node from one or more of said settled nodes using pre-computed data based on traffic prediction data, thereby to determine a route from the source node to the destination node via one of said settled nodes. Furthermore, the method comprises of estimating the refilling or recharging time of a vehicle while planning a route.
