Routesto

Routesto is a term used in routing and navigation to denote the set of feasible routes between two points within a road network. It can refer to the conceptual space of alternative paths as well as to software components that generate, compare, and present these options. In routing systems, routesto supports multi-criteria decision making by preserving several candidate routes rather than a single optimal path.

The routesto output typically includes route geometry and metadata such as total distance, travel time, toll costs, and emissions estimates, along with turn restrictions and road attributes. It enables users to apply constraints like avoiding tolls, ferries, or highways, and to optimize for different objectives such as minimum time or minimum fuel consumption. Real-time data such as traffic and incidents are often integrated to adjust rankings dynamically.

Algorithms commonly used to produce routesto include k-shortest path methods (such as Yen’s or Eppstein’s algorithms) and multi-criteria ranking approaches that combine various attributes into a composite score. Modern implementations frequently incorporate live data, historical patterns, and user preferences to rank routes and present a prioritized list of alternatives.

Data models for routesto commonly represent the road network as a graph, with nodes representing intersections and edges representing road segments. Each edge carries attributes like length, speed, cost, tolls, and road type. A route is an ordered sequence of edges, with metrics such as total distance, total time, and aggregate costs computed for comparison.

Applications of routesto span consumer navigation, logistics and delivery planning, emergency response, and urban planning, where presenting multiple viable route options supports better decision making.
