Routing algorithms

Definition

Routing algorithms are computational methods used to determine the most efficient path for data or vehicles to travel from a starting point to a destination. These algorithms are critical in both transportation systems and network design, as they help optimize routes based on various criteria such as distance, travel time, traffic conditions, and even cost. By integrating routing algorithms with geographic information systems (GIS), planners can enhance decision-making and improve the efficiency of transportation operations.
