![]() ![]() ![]() When finding closest facilities, you can specify how many to find and whether the direction of travel is toward or away from them. Learn more about finding the best route Closest facilityįinding the closest hospital to an accident, the closest police cars to a crime scene, and the closest store to a customer's address are all examples of closest facility problems. Consequently, the length of the shortest path is 4.4 miles, which takes 9 minutes to traverse.Īlong with the best route, Network Analyst provides directions with turn-by-turn maps that can be printed. In the next case, distance is chosen as the impedance. The quickest path is shown in blue and has a total length of 4.5 miles, which takes 8 minutes to traverse. In the example below, the first case uses time as an impedance. Any valid network cost attribute can be used as the impedance when determining the best route. Hence, the best route can be defined as the route that has the lowest impedance, where the impedance is chosen by the user. If the impedance is time, then the best route is the quickest route. The best route can be the quickest, shortest, or most scenic route, depending on the impedance chosen. But "best route" can mean different things in different situations. Whether finding a simple route between two locations or one that visits several locations, people usually try to take the best route. ![]() Alternatively, Network Analyst can determine the best sequence to visit the locations, which is known as solving the traveling salesman problem. If you have more than two stops to visit, the best route can be determined for the order of locations as specified by the user. The locations can be specified interactively by placing points on the screen, entering an address, or using points in an existing feature class or feature layer. Network Analyst can find the best way to get from one location to another or to visit several locations. The ArcGIS Network Analyst extension allows you to solve common network problems, such as finding the best route across a city, finding the closest emergency vehicle or facility, identifying a service area around a location, servicing a set of orders with a fleet of vehicles, or choosing the best facilities to open or close. ![]()
