A network dataset models your transportation network by encoding traffic rules, such as those governing one-way streets, turn restrictions, overpasses and tunnels, and so on.
The network dataset is accessed from a geodatabase, which can be a file geodatabase, a mobile map package stored on disk, or an enterprise geodatabase. You can create a network dataset based on the street data that your organization maintains or use a network dataset available as part of ArcGIS StreetMap Premium.
There are six types of analysis that can be performed using routing services. Each of these analysis tools is available as a service. The route service can be used to find the best way to get from one location to another or to visit several locations.
The best route can be the quickest route for a given time of day considering the traffic conditions applicable during that time, or it can be the shortest route that minimizes the travel distance. The route service can also find the best route that visits each stop during permitted time windows you specify.
If you have more than two stops to visit, the best route can be determined for the fixed order of locations you specify. Such a route is called a simple route. Alternatively, the route service can determine the best sequence in which to visit the locations the traveling salesman problem.
Such a route is called an optimized route. Finding 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 problems that can be solved using the closest facility service. When finding the closest facilities, you can specify how many to find and whether the direction of travel is toward or away from them. Once you've found the closest facilities, you can display the best route to or from them and include the travel time, travel distance, and driving directions to each facility.
The service can use current traffic conditions when determining the best routes. Additionally, you can specify an impedance cutoff beyond which the service should not search for a facility. For instance, you can set up a closest facility service to search for hospitals within 15 minutes' drive time of the site of an accident. Any hospitals that take longer than 15 minutes to reach will not be included in the results.
The hospitals are referred to as facilities, and the accident is referred to as an incident. The service allows you to perform multiple closest facility analyses simultaneously. This means you can have multiple incidents and find the closest facility or facilities to each incident.
With the service area service, you can find the area that can be reached from the input location within a given travel time or travel distance.
