A route planning platform can identify a plurality of nodes interconnected by a plurality of paths in a road network, can divide the road network into a plurality of partitions, and can generate a respective contraction hierarchy for each partition of the plurality of partitions. The route planning platform can generate, based on the contraction hierarchies of the plurality of partitions, an overlay network and can generate a contraction hierarchy for the overlay network. The route planning platform can obtain information relating to an origination point and a destination point associated with the road network and can identify a first partition associated with the origination point and a second partition associated with the destination point. The route planning platform can determine a route from the origination point to the destination point based on the respective contraction hierarchies of the first partition, the second partition, and the overlay network.

Using partitioned contraction hierarchies to determine a route from an origination point to a destination point

A route planning platform can find a path through a road network that has turn complexities. The route planning platform can identify, in the road network, multiple paths from an origin node to a destination node, including at least one path having a turn complexity (e.g., a turn cost, a turn restriction, and/or the like). The route planning platform can compute a respective cost for each respective path from the origin node to the destination node based on a total cost associated with a set of road segments in the respective path, and the cost for the at least one path having the turn complexity can be further based on the turn cost or the turn restriction along the at least one path. The route planning platform can select, among the multiple paths, a shortest path based on the respective cost for each path.
