1. A method of node-centric navigation optimization, the method comprising:
- identifying a roadway graph representative of at least a portion of a roadway, the roadway graph comprising a plurality of nodes of the roadway and a weight for each of the plurality of nodes indicative of a number of vehicles of a fleet of vehicles corresponding to a node in a path of a vehicle of the fleet of vehicles;
receiving vehicle position data from a sensor of the vehicle of the fleet of vehicles on the roadway;
identifying an affected node of the roadway based on the vehicle position data;
incrementing a weight of the affected node if the affected node is a node in a forward path of the vehicle;
decrementing the weight of the affected node if the affected node is a node in a wake of the vehicle; and
updating the roadway graph based on the weight of the affected node of the roadway, wherein a route of the vehicle is optimized based on the updated roadway graph.

Abstract
Vehicle position data from vehicles on a roadway are received. Affected nodes of the roadway are identified based on the vehicle position data. The roadway graph, representative of the roadway, is updated based on the affected nodes of the roadway. Routes of each vehicle are optimized based on updates to the roadway graph. An indication of change in the route of each vehicle may be provided for display.
