barrier

A barrier is a geometric feature that alters which streets a routeA route is a polyline that defines the best path between two or more points in a street network.Learn more can traverse in a street network. It can be a pointA point is a type of geometry containing a single set of x,y coordinates and a spatial reference.Learn more , lineA polyline is a type of geometry containing ordered point coordinates and a spatial reference.Learn more, or polygonA polygon is a type of geometry containing an array of rings and a spatial reference. Each ring contains an array of point coordinates, where the first and last point are the same.Learn more. It is used to restrict travel or proportionally scale the time or distance required to travel in a street network. Barriers often represent incidents such as traffic incidents, fallen trees, electrical lines, or flood areas that impose some form of impedance upon finding routes. Barriers are an input parameter used to find a route with the routing serviceA routing service is a service that uses network analysis and streets data to calculate the most effective path and turn-by-turn directions on a street network, optimize fleet routing and deliveries, find the closest facilities, calculate service areas, and more. It is hosted by Esri as the ArcGIS Routing service and can also be hosted in ArcGIS Enterprise.Learn more.
